Preface
Software has become a strategic societal resource in the last few decades.
Rąe emergence of Free Software, which has entered in major sectors of
the ICT market, is drastically changing the economics of software
development and usage. Free Software  sometimes also referred to as
 Open Source or  Libre Software  can be used, studied, copied,
modified and distributed freely. It offers the freedom to learn and to
teach without engaging in dependencies on any single technology
provider. Rąese freedoms are considered a fundamental precondition for
sustainable development and an inclusive information society.
Although there is a growing interest in free technologies (Free Software
and Open Standards), still a limited number of people have sufficient
knowledge and expertise in these fields. Rąe FTA attempts to respond to
this demand.
Introduction to the FTA
Rąe Free Technology Academy (FTA) is a joint initiative from several
educational institutes in various countries. It aims to contribute to a
society that permits all users to study, participate and build upon existing
knowledge without restrictions.
What does the FTA offer?
Rąe Academy offers an online master level programme with course
modules about Free Technologies. Learners can choose to enrol in an
individual course or register for the whole programme. Tuition takes
place online in the FTA virtual campus and is performed by teaching
staff from the partner universities. Credits obtained in the FTA
programme are recognised by these universities.
Who is behind the FTA?
Rąe FTA was initiated in 2008 supported by the Life Long Learning
Programme (LLP) of the European Commission, under the coordination
of the Free Knowledge Institute and in partnership with three european
universities: Open Universiteit Nederland (Rąe Netherlands), Universitat
Oberta de Catalunya (Spain) and University of Agder (Norway).
For who is the FTA?
Rąe Free Technology Academy is specially oriented to IT professionals,
educators, students and decision makers.
What about the licensing?
All learning materials used in and developed by the FTA are Open
Educational Resources, published under copyleft free licenses that allow
them to be freely used, modified and redistributed. Similarly, the
software used in the FTA virtual campus is Free Software and is built
upon an Open Standards framework.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
0. PREAMBLE
The purpose of this License is to make a manual, textbook, or other functional
and useful document "free" in the sense of freedom: to assure everyone the
effective freedom to copy and redistribute it, with or without modifying it,
either commercially or noncommercially. Secondarily, this License preserves
for the author and publisher a way to get credit for their work, while not being
considered responsible for modifications made by others.
This License is a kind of "copyleft", which means that derivative works of
the document must themselves be free in the same sense. It complements
the GNU General Public License, which is a copyleft license designed for free
software.
We have designed this License in order to use it for manuals for free software,
because free software needs free documentation: a free program should come
with manuals providing the same freedoms that the software does. But this
License is not limited to software manuals; it can be used for any textual work,
regardless of subject matter or whether it is published as a printed book. We
recommend this License principally for works whose purpose is instruction
or reference.
1. APPLICABILITY AND DEFINITIONS
This License applies to any manual or other work, in any medium, that
contains a notice placed by the copyright holder saying it can be distributed
under the terms of this License. Such a notice grants a world-wide, royalty-free
license, unlimited in duration, to use that work under the conditions stated
herein. The "Document", below, refers to any such manual or work. Any
GNUFDL " PID_00148363 12 Implementation of free software systems
member of the public is a licensee, and is addressed as "you". You accept
the license if you copy, modify or distribute the work in a way requiring
permission under copyright law.
A "Modified Version" of the Document means any work containing the
Document or a portion of it, either copied verbatim, or with modifications
and/or translated into another language.
A "Secondary Section" is a named appendix or a front-matter section of the
Document that deals exclusively with the relationship of the publishers or
authors of the Document to the Document's overall subject (or to related
matters) and contains nothing that could fall directly within that overall
subject. (Thus, if the Document is in part a textbook of mathematics, a
Secondary Section may not explain any mathematics.) The relationship could
be a matter of historical connection with the subject or with related matters,
or of legal, commercial, philosophical, ethical or political position regarding
them.
The "Invariant Sections" are certain Secondary Sections whose titles are
designated, as being those of Invariant Sections, in the notice that says that
the Document is released under this License. If a section does not fit the above
definition of Secondary then it is not allowed to be designated as Invariant.
The Document may contain zero Invariant Sections. If the Document does
not identify any Invariant Sections then there are none.
The "Cover Texts" are certain short passages of text that are listed, as
Front-Cover Texts or Back-Cover Texts, in the notice that says that the
Document is released under this License. A Front-Cover Text may be at most
5 words, and a Back-Cover Text may be at most 25 words.
A "Transparent" copy of the Document means a machine-readable copy,
represented in a format whose specification is available to the general public,
that is suitable for revising the document straightforwardly with generic text
editors or (for images composed of pixels) generic paint programs or (for
drawings) some widely available drawing editor, and that is suitable for input
to text formatters or for automatic translation to a variety of formats suitable
for input to text formatters. A copy made in an otherwise Transparent file
format whose markup, or absence of markup, has been arranged to thwart or
discourage subsequent modification by readers is not Transparent.
An image format is not Transparent if used for any substantial amount of text.
A copy that is not "Transparent" is called "Opaque".
Examples of suitable formats for Transparent copies include plain ASCII
without markup, Texinfo input format, LaTeX input format, SGML or
XML using a publicly available DTD, and standard-conforming simple
HTML, PostScript or PDF designed for human modification. Examples of
GNUFDL " PID_00148363 13 Implementation of free software systems
transparent image formats include PNG, XCF and JPG. Opaque formats
include proprietary formats that can be read and edited only by proprietary
word processors, SGML or XML for which the DTD and/or processing tools
are not generally available, and the machine-generated HTML, PostScript or
PDF produced by some word processors for output purposes only.
The "Title Page" means, for a printed book, the title page itself, plus such
following pages as are needed to hold, legibly, the material this License
requires to appear in the title page. For works in formats which do not have
any title page as such, "Title Page" means the text near the most prominent
appearance of the work's title, preceding the beginning of the body of the text.
A section "Entitled XYZ" means a named subunit of the Document whose
title either is precisely XYZ or contains XYZ in parentheses following text
that translates XYZ in another language. (Here XYZ stands for a specific
section name mentioned below, such as "Acknowledgements", "Dedications",
"Endorsements", or "History".) To "Preserve the Title" of such a section when
you modify the Document means that it remains a section "Entitled XYZ"
according to this definition.
The Document may include Warranty Disclaimers next to the notice which
states that this License applies to the Document. These Warranty Disclaimers
are considered to be included by reference in this License, but only as regards
disclaiming warranties: any other implication that these Warranty Disclaimers
may have is void and has no effect on the meaning of this License.
2. VERBATIM COPYING
You may copy and distribute the Document in any medium, either
commercially or noncommercially, provided that this License, the copyright
notices, and the license notice saying this License applies to the Document
are reproduced in all copies, and that you add no other conditions whatsoever
to those of this License. You may not use technical measures to obstruct
or control the reading or further copying of the copies you make or
distribute. However, you may accept compensation in exchange for copies.
If you distribute a large enough number of copies you must also follow the
conditions in section 3.
You may also lend copies, under the same conditions stated above, and you
may publicly display copies.
3. COPYING IN QUANTITY
If you publish printed copies (or copies in media that commonly have printed
covers) of the Document, numbering more than 100, and the Document's
license notice requires Cover Texts, you must enclose the copies in covers that
carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front
GNUFDL " PID_00148363 14 Implementation of free software systems
cover, and Back-Cover Texts on the back cover. Both covers must also clearly
and legibly identify you as the publisher of these copies. The front cover must
present the full title with all words of the title equally prominent and visible.
You may add other material on the covers in addition.
Copying with changes limited to the covers, as long as they preserve the title of
the Document and satisfy these conditions, can be treated as verbatim copying
in other respects.
If the required texts for either cover are too voluminous to fit legibly, you
should put the first ones listed (as many as fit reasonably) on the actual cover,
and continue the rest onto adjacent pages.
If you publish or distribute Opaque copies of the Document numbering
more than 100, you must either include a machine-readable Transparent
copy along with each Opaque copy, or state in or with each Opaque copy
a computer-network location from which the general network-using public
has access to download using public-standard network protocols a complete
Transparent copy of the Document, free of added material.
If you use the latter option, you must take reasonably prudent steps, when
you begin distribution of Opaque copies in quantity, to ensure that this
Transparent copy will remain thus accessible at the stated location until at
least one year after the last time you distribute an Opaque copy (directly or
through your agents or retailers) of that edition to the public.
It is requested, but not required, that you contact the authors of the Document
well before redistributing any large number of copies, to give them a chance
to provide you with an updated version of the Document.
4. MODIFICATIONS
You may copy and distribute a Modified Version of the Document under the
conditions of sections 2 and 3 above, provided that you release the Modified
Version under precisely this License, with the Modified Version filling the
role of the Document, thus licensing distribution and modification of the
Modified Version to whoever possesses a copy of it. In addition, you must do
these things in the Modified Version:
A. Use in the Title Page (and on the covers, if any) a title distinct from that
of the Document, and from those of previous versions (which should, if there
were any, be listed in the History section of the Document). You may use the
same title as a previous version if the original publisher of that version gives
permission.
GNUFDL " PID_00148363 15 Implementation of free software systems
B. List on the Title Page, as authors, one or more persons or entities responsible
for authorship of the modifications in the Modified Version, together with at
least five of the principal authors of the Document (all of its principal authors,
if it has fewer than five), unless they release you from this requirement.
C. State on the Title page the name of the publisher of the Modified Version,
as the publisher.
D. Preserve all the copyright notices of the Document.
E. Add an appropriate copyright notice for your modifications adjacent to the
other copyright notices.
F. Include, immediately after the copyright notices, a license notice giving the
public permission to use the Modified Version under the terms of this License,
in the form shown in the Addendum below.
G. Preserve in that license notice the full lists of Invariant Sections and
required Cover Texts given in the Document's license notice.
H. Include an unaltered copy of this License.
I. Preserve the section Entitled "History", Preserve its Title, and add to it an
item stating at least the title, year, new authors, and publisher of the Modified
Version as given on the Title Page. If there is no section Entitled "History" in
the Document, create one stating the title, year, authors, and publisher of the
Document as given on its Title Page, then add an item describing the Modified
Version as stated in the previous sentence.
J. Preserve the network location, if any, given in the Document for public
access to a Transparent copy of the Document, and likewise the network
locations given in the Document for previous versions it was based on. These
may be placed in the "History" section. You may omit a network location for
a work that was published at least four years before the Document itself, or if
the original publisher of the version it refers to gives permission.
K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the
Title of the section, and preserve in the section all the substance and tone of
each of the contributor acknowledgements and/or dedications given therein.
L. Preserve all the Invariant Sections of the Document, unaltered in their text
and in their titles. Section numbers or the equivalent are not considered part
of the section titles.
M. Delete any section Entitled "Endorsements". Such a section may not be
included in the Modified Version.
GNUFDL " PID_00148363 16 Implementation of free software systems
N. Do not retitle any existing section to be Entitled "Endorsements" or to
conflict in title with any Invariant Section.
O. Preserve any Warranty Disclaimers.
If the Modified Version includes new front-matter sections or appendices
that qualify as Secondary Sections and contain no material copied from the
Document, you may at your option designate some or all of these sections as
invariant. To do this, add their titles to the list of Invariant Sections in the
Modified Version's license notice. These titles must be distinct from any other
section titles.
You may add a section Entitled "Endorsements", provided it contains nothing
but endorsements of your Modified Version by various parties--for example,
statements of peer review or that the text has been approved by an
organization as the authoritative definition of a standard.
You may add a passage of up to five words as a Front-Cover Text, and a passage
of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts
in the Modified Version. Only one passage of Front-Cover Text and one of
Back-Cover Text may be added by (or through arrangements made by) any
one entity. If the Document already includes a cover text for the same cover,
previously added by you or by arrangement made by the same entity you are
acting on behalf of, you may not add another; but you may replace the old
one, on explicit permission from the previous publisher that added the old
one.
The author(s) and publisher(s) of the Document do not by this License
give permission to use their names for publicity for or to assert or imply
endorsement of any Modified Version.
5. COMBINING DOCUMENTS
You may combine the Document with other documents released under this
License, under the terms defined in section 4 above for modified versions,
provided that you include in the combination all of the Invariant Sections
of all of the original documents, unmodified, and list them all as Invariant
Sections of your combined work in its license notice, and that you preserve
all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and multiple
identical Invariant Sections may be replaced with a single copy. If there are
multiple Invariant Sections with the same name but different contents, make
the title of each such section unique by adding at the end of it, in parentheses,
the name of the original author or publisher of that section if known, or else
a unique number.
GNUFDL " PID_00148363 17 Implementation of free software systems
Make the same adjustment to the section titles in the list of Invariant Sections
in the license notice of the combined work.
In the combination, you must combine any sections Entitled "History" in the
various original documents, forming one section Entitled "History"; likewise
combine any sections Entitled "Acknowledgements", and any sections Entitled
"Dedications". You must delete all sections Entitled "Endorsements".
6. COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents
released under this License, and replace the individual copies of this License
in the various documents with a single copy that is included in the collection,
provided that you follow the rules of this License for verbatim copying of each
of the documents in all other respects.
You may extract a single document from such a collection, and distribute it
individually under this License, provided you insert a copy of this License into
the extracted document, and follow this License in all other respects regarding
verbatim copying of that document.
7. AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate and
independent documents or works, in or on a volume of a storage or
distribution medium, is called an "aggregate" if the copyright resulting from
the compilation is not used to limit the legal rights of the compilation's users
beyond what the individual works permit.
When the Document is included in an aggregate, this License does not apply
to the other works in the aggregate which are not themselves derivative works
of the Document.
If the Cover Text requirement of section 3 is applicable to these copies of
the Document, then if the Document is less than one half of the entire
aggregate, the Document's Cover Texts may be placed on covers that bracket
the Document within the aggregate, or the electronic equivalent of covers if
the Document is in electronic form.
Otherwise they must appear on printed covers that bracket the whole
aggregate.
8. TRANSLATION
Translation is considered a kind of modification, so you may distribute
translations of the Document under the terms of section 4. Replacing
Invariant Sections with translations requires special permission from their
GNUFDL " PID_00148363 18 Implementation of free software systems
copyright holders, but you may include translations of some or all Invariant
Sections in addition to the original versions of these Invariant Sections. You
may include a translation of this License, and all the license notices in the
Document, and any Warranty Disclaimers, provided that you also include
the original English version of this License and the original versions of those
notices and disclaimers. In case of a disagreement between the translation
and the original version of this License or a notice or disclaimer, the original
version will prevail.
If a section in the Document is Entitled "Acknowledgements", "Dedications",
or "History", the requirement (section 4) to Preserve its Title (section 1) will
typically require changing the actual title.
9. TERMINATION
You may not copy, modify, sublicense, or distribute the Document except
as expressly provided for under this License. Any other attempt to copy,
modify, sublicense or distribute the Document is void, and will automatically
terminate your rights under this License. However, parties who have received
copies, or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
10. FUTURE REVISIONS OF THIS LICENSE
The Free Software Foundation may publish new, revised versions of the GNU
Free Documentation License from time to time. Such new versions will be
similar in spirit to the present version, but may differ in detail to address new
problems or concerns. See http://www.gnu.org/copyleft/.
Each version of the License is given a distinguishing version number. If the
Document specifies that a particular numbered version of this License "or any
later version" applies to it, you have the option of following the terms and
conditions either of that specified version or of any later version that has been
published (not as a draft) by the Free Software Foundation. If the Document
does not specify a version number of this License, you may choose any version
ever published (not as a draft) by the Free Software Foundation.
ADDENDUM: How to use this License for your documents
To use this License in a document you have written, include a copy of the
License in the document and put the following copyright and license notices
just after the title page:
Copyright (c) YEAR YOUR NAME.
GNUFDL " PID_00148363 19 Implementation of free software systems
Permission is granted to copy, distribute and/or modify this document under
the terms of the GNU Free Documentation License, Version 1.2 or any
later version published by the Free Software Foundation; with no Invariant
Sections, no Front-Cover Texts, and no Back-Cover Texts.
A copy of the license is included in the section entitled "GNU Free
Documentation License".
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
replace the "with...Texts." line with this:
with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover
Texts being LIST, and with the Back-Cover Texts being LIST.
If you have Invariant Sections without Cover Texts, or some other
combination of the three, merge those two alternatives to suit the situation.
If your document contains nontrivial examples of program code, we
recommend releasing these examples in parallel under your choice of free
software license, such as the GNU General Public License, to permit their use
in free software.

Introduction
This module looks in detail at the methodology used to implement free
software systems in organisations and generic scenarios, establishing the main
features that will guide the project and its development.
Technology is now becoming a strategic factor in both public and private
organisations, whether small, medium or large. The integration of technology
in all of the organisation's functional and operating processes means that its
state of operation is closely related to the production of the organisation. As
a result, we need to systematically monitor the efficiency and effectiveness of
the system in order to control performance in line with the evolution of the
strategic needs of the organisation.
The implementation of systems cannot be left at random or to the
convenience of factors that are irrelevant to the organisation because the
results can be unexpected and have consequences of varying magnitudes for
the organisation. Hence, we can see the need for a rigorous implementation of
systems with the methodology used in scientific and technological circles, by
which we establish a framework of support with guarantees for management
of the complexity, development of the project and management of the risks
inherent both to the technology and the system implementation process.
The main aim of this module is to provide a broad and detailed vision of
the main processes related to the implementation of free software systems,
both in a generic or abstract context and from a perspective focusing on the
characteristics of the functional and operational management of the project
to implement the system, or considering the free software business as a valid
and viable option for a profitable company.
All of the above must be subject to a methodical and rigorous management
allowing, on the one hand, satisfactory management of the complexity of
solving the specific problems of the systems implementation project and, on
the other, keeping under control all of the potential risks that could cause the
project to fail in one way or another, whether prematurely or while the system
is already in operation, both important consequences for the organisation and
its users.
The contents of this module are divided into three units that gradually
introduce the key theoretical concepts of the process of implementing a
system in an organisation. Its sections present the implementation of systems

from that of the implementation of free software as a profitable business. A
brief summary then follows of the main features of each of the units in this
module.
The first section, "Introduction to systems implementation", gives a general
presentation of systems implementation and the features of free software.
We define the term "systems implementation" as an action resulting from
the strategy of the organisation, detailing the different reasons leading to
implementation, the main stages of the process and a classification of the
main typologies based on project context and aim. We present the specific
features of free software, their effects on systems implementation and the
functional management of the project in terms of scope, time, integration,
cost, quality, human resources, communication and risks.
The second section, "Free software projects", presents the free software
implementation project in detail from the point of view of its
methodology. We define the life cycle of the project and its main
characteristics, repercussions and relationship with the aims. The stages of the
implementation project are described in detail: study of the current situation,
study of implementation issues, analysis of free software solutions, formalising
of the proposal, development, implementation and migration, and lastly,
training, communication and support for users. Each of the stages is defined
and described in detail in relation to its specific and global objectives.
The third section, "Free software companies", provides a detailed description
of free software companies as a valid and viable alternative to sales of copies
of software. We present the main business models for free software, based
primarily on the production and sale of extra services. Lastly, we take a detailed
look at the features of the business plan of free software companies, focusing
on aspects such as definition, scope, organisation, human resources and
materials, production, product evolution, quality control and monitoring,
guarantees and user support, economics, financing and the project feasibility
study.
We hope that the conceptual, methodological and practical formalising of the
main aspects of the project to implement free software systems will enable
you to understand the need for and importance of the process and the actions
that must be taken to guarantee the strategic aims of the project.

1.Introduction to the implementation of free
software systems
This first module of this subject, Implementation of free software systems,
provides the basis for discovering the main concepts of the implementation
of systems in general, and its application to free software in particular.
The module begins with an overview of the basic concepts of systems
implementation projects, characterising the different phases of the process
from a methodological and functional point of view and analysing the close
relationship between the strategic objectives of the organisation and the
implementation project.
We then provide a classification of the most common types of implementation
project, indicating their basic characteristics and the differences between
them, and carefully analysing the implications of this for the objectives and
performance of the project.
After summarising the basic concepts of systems implementation and the
different types of project it includes, we look at the specific features of
the implementation of free software systems. We analyse the main factors
influencing the project and the pros and cons of implementation with free
software.
Lastly, we look at the basic concepts of project management and expand on
the classical models in order to adapt them to the specific features of free
software implementation.
1.1. Basic concepts
This first section provides an overview of the basic concepts of systems
implementation, from conceptual definition to its main phases, including
methodological, strategic and organisational aspects.
1.1.1. Definition
Systems implementation has always been closely associated with the
evolution and popular diffusion of technology. In fact, if we consider
this concept from a global perspective, any innovation  technological or
otherwise  that we wish to extend beyond the borders of the context of its
creators needs to undergo an implementation process.
GNUFDL " PID_00148382 12 Free software implementation, projects and companies
When implementing technology, we need to pay attention to certain basic
aspects, such as the impact on the organisation and direct users, but also
on indirect users and clients, for example. Furthermore, technology  in
the global and generic sense  is currently seen as a decisive factor in the
competitive evolution of organisations.
Systems implementation is the process by which one or more
technological innovations are introduced into an organisation, as the
result of an action deriving from its strategic plan.
In line with this definition, the implementation of technological systems is
the result of an organisation's strategic desire to reach new milestones, whose
aims can be very wide-ranging, depending on the context of the organisation.
We can illustrate this concept with two examples from different contexts:
" Companies, as profit-making organisations, can take action concerning
the technology they use in an attempt to increase their competitiveness
and obtain greater market shares, thus being able to offer more innovative
products or ones tailored to new demands.
" Government agencies, as non-profit-making organisations, can take
action concerning the technology accessible by the region they govern in
an attempt to provide competitive tools that will reduce the digital divide
and develop the sector's economy.
1.1.2. The organisation's strategic plan
In the previous section we mentioned the organisation's strategic plan and its
important role in systems implementation.
An organisation's strategic plan is a series of proposals setting down
the future aims or directions of the organisation. It usually covers a
five year period and is developed in the diverse divisions or functional
departments of the organisation.
The main aim of the plan is to minimise the risks and maximise the results
of implementation by marking out real, affordable and measurable directions
generated by the relationship between the organisation and the area in which
operates.

the structural operation of the organisation in its context at a given time.
Considering that the system implemented has to meet the current and future
needs of the organisation, we can understand the importance of the link
between the organisation's strategic plan and the implementation project.
The organisation's strategic plan evolves over time and adapts dynamically
to changes in the context in which it is carried out. Additionally, the
organisation's system must evolve with strategic changes and must conclude
some of the actions begun with a new systems implementation project.
1.1.3. Origin of systems implementation
In the preceding paragraphs, we saw the link between the implementation
project and the organisation's strategic plan. Organisations do not introduce
implementation projects without first determining that they are necessary for
their specific strategies.
Thus, the implementation of a system requires having detected
deficiencies in the organisation's current system, although they can
also be implemented in new organisations or those without prior
technological positioning.
Broadly speaking, there are four generic origins leading to the implementation
of a new system:
" Detection��of��problems: there may be diverse cases in which the current
system operates inefficiently, which compromises the everyday tasks of its
users and the reliability of the system.
In these cases, the strategic plan is chiefly affected by loss of performance
and efficiency in the organisation.
An example of this type of situation could be programming errors that
produce inaccurate calculations, access errors or system locking.
" System��evolution: this covers situations in which the current system is
functionally obsolete, which compromises the organisation's operation
due to the lack of features to solve the increasing number of issues in the
organisation.
In these cases, the strategic plan is affected by the organisation's loss of
effectiveness. An example of this type of situation might be the need to
increase features following a change in legislation.
GNUFDL " PID_00148382 14 Free software implementation, projects and companies
" System��enhancement: in these situations, the system in place is
structurally obsolete, which compromises the organisation's operation
due to the poor performance of the platform of the current system.
In these cases, the strategic plan is affected by the loss of performance
and efficiency of the organisation. An example of this situation might
be the lack of integration of new operating systems or different types of
hardware.
" New�� strategic�� action: this includes possible updates, changes or
innovations in the organisation's strategic plan not covered by the current
system.
In these cases, the strategic plan is affected by the organisation's loss of
effectiveness. An example of this type of situation might be an increase in
the services offered or expansion of the target market.
The above list of possible origins is not all-inclusive but it does indicate the
most logical reasons for systems implementation. In addition, the different
cases are not mutually exclusive and their coincidence can be strongly
motivated by the evolution of the organisation and its system.
1.1.4. Resources of a systems implementation project

implementation project. Initially, these resources usually take the form of one
or more individuals with free time to spend on the project, with the financial
repercussions that this will have on the everyday workings of the organisation
(insourcing2).

Some organisations prefer to leave this task to professionals outside

objectivity, production capacity or time availability. In these instances, it is
not the case that the organisation spends no time at all on the project; rather,
this time is reduced by the degree to which outsourcing increases, since both
the organisation and the external professionals need one another to bring the
project to successful completion.
One of the key points of an implementation project, regardless of its final
form of execution, is the creation of a supervisory or monitoring committee
for the project (executive committee in some organisations). This committee
is charged with the methodological execution of the project and its adequate,
gradual and sustained progress over time.
The supervisory committee is normally made up of individuals from the
various divisions affected by implementation, mainly management staff and
heads of department. If the organisation contracts external professionals to
GNUFDL " PID_00148382 15 Free software implementation, projects and companies
manage the implementation, they will also form part of the committee.
Although most of the committee members only spend part of their time on
it, there is usually at least one member that works on the project full-time to
ensure rigorous monitoring.
The importance of resources in the implementation of a system is twofold:
" Firstly, human resources are allocated based on the quantity and quality
in the analysis and design of the system implementation.
" And secondly, material resources are allocated according to the quality and
quantity of the system to be implemented.
In all events, the resources allocated to a systems implementation project will
have a direct effect on the finances of the organisation.
1.1.5. The main stages of a systems implementation project
As we explained above, a systems implementation project is a methodological
process designed to adapt the system to the strategic plan. This process must
be performed with due care and attention in order to guarantee the success
of the project.
From a generic point of view, we can break the systems implementation
process down into four main phases: analysis of the current system,
design of the new system, development, and implementation of the
system.
Analysis��of��the��current��system
All implementation projects begin with a study and analysis of the current
status of the organisation in the terms indicated by the strategic action. There
are two possible initial situations:
" If the organisation has a system in place, its characteristics are assessed
by collecting information on the elements affecting the strategic action
and their structure. The aim of this is to create an abstract framework for
adapting the system to the new strategy.
" If the organisation does not have a system in place (or it is a new
organisation), we need to evaluate the features of the area of action that
will be affected by the strategic scope of the organisation's operation. We
will need to create an abstract framework of aims that the implementation
project must meet.
GNUFDL " PID_00148382 16 Free software implementation, projects and companies
In either case, this stage defines and determines the problems that the
implementation project will need to overcome, given that we will select the
different aims of the strategic action. We evaluate aspects such as system
history, structure and operation or the evolution of issues and workload over
time. Many of these results are presented in the form of charts or diagrams.
The stage ends with a presentation of the conclusions of the study and an
analysis of the current status, which evaluate the extent to which the system
can stand up to new strategic challenges.
Design��of��the��new��system
Once we have assessed the initial situation of the organisation, defined the
main points of the strategic action and received confirmation of monitoring
from the project's executive committee, we can begin to design the new
system.
This stage begins with a thorough analysis of the issues that the new
implementation will need to resolve, based on the strategic actions we have
defined. We will come up with different solutions or alternatives for these
problems that we will need to analyse individually to gauge their suitability
and determine their costs, advantages and disadvantages, both tangible and
intangible. Depending on the type of project and strategic action, this
evaluation will cover a five-year period.
We must be objective and use a methodology when choosing our solution
in order to maximise the advantages and minimise the disadvantages
both of implementation of the solution and its everyday operation. Some
decision-making criteria may concern the scope of the action, performance,
the necessary equipment, the requirements covered, provider support,
availability of equipment and support, and the maintenance required over
time.
Development��of��the��new��system
After receiving confirmation of the project monitoring by the supervisory
committee, we can begin to develop the new system.

Implementation��of��the��system
GNUFDL " PID_00148382 17 Free software implementation, projects and companies
Once the new system is ready, we can begin the implementation phase, which
involves setting up the system in the organisation.
This phase sees the completion of the adaptation and integration of the new
system into the real environment and covers user training, pilot tests and
system integration with end user testing, and the conversion and final release
of the new system.
If the organisation already has a system in place, we must also take into
account the migration from the old system to the new one. Migration involves
transferring the current status of the system in place to the new system. Data
transfer is usually the most important task of migration, since this activity
cannot affect the day-to-day running of the organisation.
This stage ends with the final implementation of the new system, data
migration and user training. In other words, we will have fully introduced
the elements needed for performance of the strategic action we defined at the
start.
Although a considerable proportion of the implementation project is
completed with the implementation of the system, the maintenance and
continuous evaluation of the system's feasibility remain active as in any other
project, particularly if the new implementation is regarded as a strategic factor
in the competitiveness of the organisation.
1.1.6. Feasibility and evaluation of the project
The previous section outlined the main phases of a systems implementation
project but we also need to consider the importance of at least two control
points for the project.
The first is the feasibility and continuation of the project, which is assessed
on the basis of two milestones:
" The first milestone occurs after the current status analysis stage, in which
we analyse and discuss the current system status in terms of the strategic
action.
" The second milestone takes place after the design stage, which involves
an analysis and discussion of the proposed solutions.
For instance, the convenience of continuing the project could be questioned
given the financial implications of its development.
GNUFDL " PID_00148382 18 Free software implementation, projects and companies
The second control point is the project evaluation, which takes place once

measurable indicators are observed from a longitudinal perspective.
For example, we can evaluate the impact of the new system on the
organisation's production capacity or on its ability to attract new clients.
1.1.7. Project methodology
As in all strategic projects, systems implementation must be carried out in a
methodological, structured and orderly way. The importance of the project
outcome for the development of the organisation dictates the precision with
which it needs to be carried out.
To illustrate this concept, we can contrast it with the methodology applied
to life cycle in software development and the importance of the conceptual
analysis and solution design phases. Here we can see the problems caused
by not detecting failures in the analysis and design stages. Solving a design
problem detected at the development stage is generally considered to have a
possible cost ratio of one to ten.
Systems implementation projects also require maximum precision in the
analysis and design phases because of the strategic implications of the new
implementation on the organisation's evolution.
The stages described in the previous sections have a sequential behaviour,
inherent to their aims, but we can still specialise the methodology for
execution of each stage in order to achieve our aims more efficiently. One
example would be the distribution below:
" The current system analysis phase may use an iterative method, with
feedback obtained from the study results.

infrastructure.
" The implementation phase can use an iterative process if it affects a
number of units, with the possibility of maintaining more than one line
of implementation for each time unit.
GNUFDL " PID_00148382 19 Free software implementation, projects and companies
In all events, we will need to adapt the methodology of each stage to the
convenience of the project and the organisation, always with the aim of
maximising efficiency and minimising any negative impact.
1.2. Types of project
This section contains a general classification of the different types of
implementation project and describes the diverse features and main
implications for project development.
It offers two classifications, one based on project scope, that is, the
repercussions and scope of the implementation, and a second that considers
the aim of the project, that is, the contents of the implementation.
This classification should not be regarded as a rigid structure, since the true
diversity of the projects allows a combination of different typologies.
1.2.1. Classification by scope
We can define three broad scopes of action for implementation projects:
1)��Internal
Projects whose scope is internal are designed to implement a local
system in an organisation that will primarily be used internally.
Examples of projects with an internal scope are those implementing local
network services (directory, authentication or data sharing services), those
implementing tools in local groups (internal mail or groupware) or those
implementing internal management tools (ERP systems).
The strategic aim of this type of project is to introduce functional internal
improvements to the efficiency and efficacy of work through technological
renovation. These are normally used in scenarios in which the current system
reveals functional deficiencies or is unreliable.
The main implications for project development are as follows.
" Evaluation��of��the��current��system: This stage basically evaluates the
system from a functional perspective, pinpointing and evaluating the
aspects of the system that could cause problems, always taking the
strategic action outlined by the organisation as a reference.
" Design��of��the��new��system: The issues analysis carried out at the design
stage must allow us to compare two alternatives for implementation:
GNUFDL " PID_00148382 20 Free software implementation, projects and companies
on the one hand, evolution of the current system, and, on the other, a
complete overhaul of this system.
While evolution seeks to partially update the current system in order
to extend its useful life, a complete overhaul requires changing various
elements of the system (hardware and/or software).
" Development��of��the��new��system: There are no major differences in the
development stage. In all events, the local scope of the project can help
us to define the latter and provide a strategic resolution.
" Implementation: The project's internal scope can help with progressive
implementation (of time and/or services) which, along with staff
training, must contribute to the creation of a mood of acceptance while
guaranteeing the day-to-day operation of the organisation.
2)��External
The aim of external projects is to implement a system essentially
for public use in the organisation, connecting external agents to the
organisation. The system can be placed locally or remotely.
Examples of projects with an external scope are those that implement
corporate intranets or extranets (tailored access to workers, clients
or suppliers) or implementation of electronic government services
(e-government or e-voting).
The strategic aim of this type of project is to introduce functional
improvements to the organisation in its external dealings, enhancing
the efficiency and efficacy of its communication through technological
renovation. They are normally used in scenarios in which the management of
digital relations with third parties is complex or inefficient and in cases where
we are looking to improve the corporate image and target market.
The main implications for project development are as follows.
" Evaluation��of��the��current��system: This stage basically evaluates the
system from a relational, communicative and interactive perspective. Data
collection cannot be limited to the internal part of the organisation, so
contact with external agents will be required. Regardless of whether or
not there is a system in place, the aim of the strategic action will be
to highlight the shortcomings and weaknesses of the current relational
implementation.
" Design��of��the��new��system: The design of the new system basically needs
to cover two types of aim: the efficiency and efficacy of user functionality,
GNUFDL " PID_00148382 21 Free software implementation, projects and companies
and considerations relating to the corporate image that the organisation
wishes to convey to the target market.
" Development��of��the��new��system: There are no major differences
in the development stage. However, it should be noted that security
management is particularly important with this type of project.
" Implementation: The full implementation of these systems can be carried
out in two phases: we can first set up the basic system and then we
can progressively update the services and contents over time, taking into
account the opinions of external users on the changes that have taken
place (feedback).
3)��Productive
The aim of projects with a productive scope is to implement a system in
a different environment to that of the organisation managing and/or
developing the project (outsourcing).
Examples of projects with a productive scope include core software
implementation (operating systems), specialist software implementation
(office automation tools, accounting, invoicing, etc.) and implementation of
outsourced services (subcontracting of website services).
The strategic aim of this type of project is to meet the demands or needs for
technology services of other organisations or external groups from diverse
fields. It is normally used in scenarios associated with opportunities for a
strategic and technological change in the target market.
The main implications for project development are as follows.
" Evaluation��of��the��current��system: This stage basically evaluates the
system from two different angles. Firstly, specialised projects for an
organisation with specific strategic needs to be met.
And secondly, direct implementation projects (operating systems or office
automation tools), designed to provide generic solutions for a large market
segment. In both cases, the importance of studying the status of the
current situation is clear.
" Design��of��the��new��system: There are no significant differences in the
design stage. Specialised projects are carried out in accordance with the
internal or external project considerations in the client organisation while
direct implementation projects need to meet everyday operating needs
GNUFDL " PID_00148382 22 Free software implementation, projects and companies
and/or offer new features. The technology used in the project is important
for the corporate image of the organisation.
" Development��of��the��new��system: There are no major differences in the
development stage. It is important for the development to meet the aims
of the client organisation efficiently and effectively, and that this is done
within the fixed time limit.
" Implementation: Specialised projects are implemented based on typology
(internal or external project), with an emphasis on user training
and communication. Direct implementation projects are normally
implemented as a self-installing product package (on CD-ROM or
DVD-ROM, or as a download from the Internet). Some services can be
considered extras (training, migration, etc.) and supplied on request by
the organisation or by third parties.
1.2.2. Classification by requirement aim
Three main groups of aim can be defined for implementation projects:
1)��Software
The aim of software development projects is to implement applications
to meet certain demands. This type can also include projects for the
adaptation, reengineering or integration of software or tools, such as
the adaptation of operating systems or the integration of specialised
software packages.
The strategic aim of this type of project is to provide a technological response
to a specific functional problem. It is normally used in scenarios where systems
are implemented to automate tasks, provide efficient technological support to
users or to evolve or replace obsolete software.
The main implications for project development are as follows.
" Evaluation��of��the��current��system: This stage basically evaluates the
system from a functional perspective, evaluating overall efficiency and
efficacy in terms of the strategic action that launched the project.
In projects involving the creation of new or generic software, the
evaluation focuses on the study and analysis of the current status of the
target market and its main directions.
GNUFDL " PID_00148382 23 Free software implementation, projects and companies

" Development��of��the��new��system: There are no major differences in the
development stage regarding the usual life cycle of this type of project.
Aspects of importance include the mechanisms guaranteeing the quality
of the code produced and the evolution of the code in versions and
revisions.
" Implementation: We can distinguish between two possibilities at the
system implementation stage. On the one hand, the development of
software that needs to be installed in an organisation, which will follow
the usual process, taking into account the possible need for migration
if there is a system already in place. And on the other, common or
generic software, which is usually implemented as a self-installing product
package on a CD-ROM or DVD-ROM, or as a download from the Internet.
Some services can be considered extras (training, migration, etc.) and
supplied on request by the organisation or by third parties.

basis to meet the requirements of the organisation. It is normally used
in scenarios of new creations or technological renovation due to the
system becoming obsolete. We need to remember that the organisation's
infrastructure is its functional basic architecture, on which the rest of the
technological elements will be organised.
The main implications for project development are as follows:
" Evaluation��of��the��current��system: This stage basically evaluates the
system from a functional perspective, taking into account aspects such
as efficiency and efficacy as well as reliability and adaptation to the new
standards of technological evolution.
GNUFDL " PID_00148382 24 Free software implementation, projects and companies
Where there is no previous system in place, we will basically need to take
into account the needs (quality and quantity) of the organisation, together
with current directions and standards.
" Design��of��the��new��system: The design stage deals mainly with the
research and study of the diverse solutions available on the market,
although we cannot rule out the creation or evolution of a solution if
the needs of the organisation so require. By comparing these options, we
should come up with the product that best fits the strategic action, taking
into account evaluation criteria such as the scope, efficiency and efficacy
of the solution, equipment and support requirements, availability and
product maintenance.
" Development��of��the��new��system: The system development stage involves
the preparation of procedures to implement the infrastructure, bearing
in mind that it is sometimes necessary to tailor the product or adapt
configuration files.
" Implementation: If the new system replaces an earlier one, we will
need to migrate from one system to the other. Nonetheless, we can
split implementation into two phases: firstly, the installation and
configuration of the new system features and secondly, start up and status
restore.
User training and communication are essential for this type of project
to ensure acceptance of the new features and for an assessment of its
operation after start-up.
3)��Systems��migration
The aim of systems migration projects is to transfer the status of the
current technological architecture to a different one. These projects
are implemented when one or more main elements of the system are
updated.
The strategic aim of this type of project is to minimise the impact
of technological changes on the operation of the organisation. It is
normally used in scenarios where new software systems or infrastructures are
implemented, but they can also be developed independently to replace the
physical technological platform in order to improve performance, reliability
or in the event of obsolescence.
The main implications for project development are as follows:
" Evaluation��of��the��current��system: This stage evaluates the system
primarily from the point of view of preserving the configuration and
GNUFDL " PID_00148382 25 Free software implementation, projects and companies
stored data. It is important to adopt a methodological approach in the
research and evaluation of the various elements that need to be migrated
to the new system.
" Migration��design: The design stage normally involves studying and
analysing the methods and procedures that we will need to implement
to transfer the status between the two systems. We can consider aspects
such as the preparation of backups or the design of procedures to export
or convert the data in the current system.
" Migration�� development: Migration development requires the
performance of all tasks to preserve the data and configuration, and to
export and convert the current system. With this task, we must take into
account the importance of the temporary location, to ensure that data
is transferred fully without interrupting the day-to-day operation of the
organisation. We also need to consider the security guarantees of the
backup medium.
" Implementation: Implementation covers start-up of the new system and
the status restore of the organisation's previous system. The timing of this
process must be planned in conjunction with the migration development
stage in order to minimise the impact of the change on the day-to-day
operation of the organisation, although the progressive restoring of some
minor elements may be possible. Communication and collaboration with
users is particularly important in this type of project if we are to meet the
aims of migration successfully.
1.3. Free software systems
This section introduces the specific features of the implementation of free
software systems. We will analyse the main factors affecting the project and
the myths, advantages and disadvantages of using this type of software.
When we talk about free software, we generally refer to its advantages,
which are fairly well-known. For instance, free software is secure and
good quality, is distributed freely, uses open standards and is based
on the culture of collaboration and promotes the latter. What is
more, it can be used anywhere, enhances technological capabilities,
helps to reduce overheads and operating expenses in IT systems,
reduces dependence on providers and fosters the development of local
companies.
GNUFDL " PID_00148382 26 Free software implementation, projects and companies
However, the companies that implement free software systems come up
against a series of problems that is hindering the sector's development (S�ez
et al).
Generally, to encourage the development of a technology, we need this
technology to be commercially viable  i.e. there has to be a supply and
demand  and economically feasible, in that the companies from that sector
must generate profits through their implementation of the technology.
With demand, that is, the companies that could adopt the free software,
the main obstacles are piracy, fear of change and misgivings. Companies
confuse free software with freeware, and some companies rule out its
implementation either because free software of similar standards is not
available or because they do not believe that there are companies behind this
software guaranteeing its support and maintenance.
With supply, that is, the companies that provide the applications and free
software services, the main obstacles are fear of change and the lack of
cooperation.
On the whole, IT companies are used to developing tailored software solutions
without giving their clients the sources, and setting up a model of licence
payments for their use. And yet, with the appearance of free software, some
companies are seeing that a business model based on payment for services
rather than licences can be sustainable, leading them to release part of the
code that was thus far kept private. Therefore, one possibility that could be
used initially by many companies would be to offer two solutions to clients:
ownership (with a licence fee) and free (normally without a licence fee). This
is just one of many possible business models for free software.
IT companies are also used to developing software on an individual basis
but a better option would be to develop the cooperative model. This would
involve drawing on work done by others, collaborating, and transferring
licence savings to the end client.
Free software projects may be approached as normal projects from the point
of view of software engineering and project management. However, a closer
look will reveal certain differences and specific features that are often only
dealt with correctly with experience and whose omission can affect and even
bring about the failure of some projects.
In the light of this, the use of a comprehensive methodology for the
implementation of free software systems is essential, particularly because:
GNUFDL " PID_00148382 27 Free software implementation, projects and companies
" It gives clients��more��confidence in the quality of the products and
processes, whether we are developing a new programme or application,
migrating an existing system or starting up a new one.
" It allows providers to systematise the procedure for the��implementation
of��free��software��systems and become familiar with their features, which
results in improved efficiency and allays fears of change.
1.4. Management of free software projects
Project management is traditionally divided into nine areas of
knowledge:
" Scope
" Time
" Integration
" Cost
" Quality
" Human Resources
" Communication
" Risks
" Supplies
This section will look at each of these in turn and study their specific features
when applied to projects implementing free software systems.
1.4.1. Scope management
Scope management involves defining the aims of the project so that we can
check to see that they are being met and, if needed, change them. In other
words, scope management ensures that the project carries out all necessary
work  and only the necessary work  so that the initial aims can be met.
Definition��of��the��project��scope
To define the scope of a project, the project manager must establish the
project work breakdown structure (WBS), which divides the project into work
packages, usually represented in the form of a logical tree. A work package
is the smallest unit into which a project can be divided in order to make it
independently manageable.
GNUFDL " PID_00148382 28 Free software implementation, projects and companies
We therefore need to identify everything that needs to be done in the project
through its WBS, briefly describing its work packages and the deliverables that
each one needs or facilitates.
Changes��to��project��scope
It may sometimes be necessary to modify the scope and aims of the project
during its execution. This can be due to the following:
" Shortcomings in the original project plan, especially incorrect definition
of the scope.
" Changes to the needs and requirements of the client established in the
initial project plan.
" Changes to the context of the project and hence, to the hypotheses
considered when the initial project plan was drawn up.
These contingencies may have a significant impact on project execution,
modifying and even preventing it from achieving its aims. Thus, it is essential
to control changes and to take into account risk management.
Scope��management��in��free��software��projects
The features of scope management in free software projects are the same as
those of any other software project. It is essential to obtain and conduct a
detailed analysis of client requirements  and of the current situation of the
system if dealing with a migration project.
The definition of the scope of free software projects will generally depend
on the motivation for the project: cutting costs, system improvement,
independence of distributors or regularising the software licence situation.
Lastly, it is important to note that clients may not always be aware of the
consequences of changes to the project once it is underway.
1.4.2. Time management
The purpose of time management is to ensure that the project is carried out
within the set deadlines. This means that we will need to define the sequence
of activities to be performed, along with their duration and coordination.
Good time planning is an essential part of project management because it
establishes the model by which the project will be carried out. Moreover, it
allows us to ensure that the aims are being met, it lays the foundations for
integrating time, costs and resources, and it sets down a common framework
for the various individuals and partners taking part in it.
GNUFDL " PID_00148382 29 Free software implementation, projects and companies
Project��network
The WBS we saw in the previous section is used to identify the activities
needed to conduct the project, taking into account the fact that an activity
is the smallest part of work into which a project can be divided for planning
purposes.
Following on from this, we need to identify the order in which the activities
will be carried out: independent activities can be carried out simultaneously
while dependent activities require the result of a previous activity for their
performance.
Gantt��chart
A Gantt chart is a tool used to help solve the problem of scheduling activities
(i.e. their organisation on a calendar) and represent in pictorial form the
duration of each activity, its start and end dates and hence, the total time
needed to complete the project. Gantt charts also enable us to monitor the
project's progress because they indicate the completed percentage of each
activity and detect advances or delays in the initial planning.
Gantt charts have a system of coordinates representing:
" Horizontal axis: time scale, in the appropriate units for the project (usually,
days, weeks or months).
" Vertical axis: work packages, activities and subactivities identified in the
WBS, whose duration is represented on the horizontal axis.
The main advantage of Gantt charts is that we do not need masses of
information to be able to use them; in fact, all that is needed is a rough outline
of the project. Hence, they are straightforward to use and particularly effective
in the initial planning of the project. However, once the project is underway,
particularly if it is very complex, Gantt charts can become confusing.
Critical��path��method��and��PERT
To overcome the limitations of Gantt charts, other tools have been developed,
such as the critical path method (CPM) and the PERT method.
The critical path of a project is the sequence of activities that generates
the maximum accumulated time. It determines the shortest time taken to
complete the project if we have all of the necessary resources. To do so, we
need to identify all of the activities correctly and know their duration.
GNUFDL " PID_00148382 30 Free software implementation, projects and companies
To represent the activities and time dependencies, directed graphs are used,
whereby each arrow represents an activity identified by its name and duration,
so their status changes as the project progresses. Each status is represented by
a node between two or more arrows. Thus, some tasks can be conducted at
the same time whereas others cannot.
The main difference between CPM and PERT is their time estimates. CPM
considers activity times ( m ) to be known exactly and to vary according to the
resources allocated to them. PERT, on the other hand, assumes that activity
times ( Te ) are determined by a probability distribution generated by the most
likely time estimate ( m ), the most optimistic time estimate ( a ) and the most
pessimistic time estimate ( b ). Thus, the most pessimistic and most optimistic
times give a measure of the uncertainty of each activity.
The following steps are taken to calculate the critical path:
1. Calculate Te or m for each activity, depending on the method used.
2. Calculate the early start dates of each activity (ES) and the last start dates

module.
A critical activity is one whose start and end points cannot be changed without
modifying the total duration of the project. Critical activities have no float and
the sequence of these critical activities is the critical path. To put it another
way, in a critical activity, the early start date will coincide with the latest start
date and the earliest finish date will coincide with the latest start date of the
activity.
Time��management��in��free��software��projects
The features of time management in free software projects are theoretically
the same as those of any other software project.
GNUFDL " PID_00148382 31 Free software implementation, projects and companies
In projects developing programmes and applications in which the community
of free software developers plays a key role, correct calculation of software
development deadlines is essential. To do this, we need to know the
background of the community and discuss the future implementation plan.
It is also a good idea to get involved in the community and learn about how
it works before starting the project.
In migration projects, we need to set aside the right amount of time for
training users and introduce a degree of flexibility for the migration of users.
As a result, some free software projects can be accompanied by a degree of
uncertainty, so we recommend the use of the PERT technique to characterise
the most optimistic and pessimistic scenarios in the project plan.
There are many free applications to create and maintain PERT and Gantt

Examples of free applications

ganttproject.sourceforge.net/ )
1.4.3. Integration management
and OpenWorkbench ( http://
www.openworkbench.org/ ).
The purpose of integration management is to ensure that the different parts
of the project are coordinated correctly. This includes developing the project
plan and the project execution plan and tracking any changes that may occur.
Integration��management��in��free��software��projects
The features of integration management in free software projects are generally
the same as those of any other software project, but we need to bear in mind
a few points.
By and large, integration in free software based projects has certain advantages
over that of proprietary software projects, mainly due to their open source
and the use of open standards for interoperability between applications,
particularly with those developed outside the project.
In development projects carried out in collaboration with a community not
forming part of the project, it is important to make known and discuss the
implementation plan both of the project and the community, in order to
identify possible incompatibilities that could affect integration.
1.4.4. Cost management
The purpose of cost management is to conclude the project with the budget
approved at the start. This means planning the required resources and
estimating and monitoring costs.
Cost��management��in��free��software��projects
GNUFDL " PID_00148382 32 Free software implementation, projects and companies
Cost management in free software projects differs considerably from that of
proprietary software projects.
The main difference lies in licence costs, which are normally non-existent for
free software. In contrast, we will need to take into account the costs of services
provided by third parties, in accordance with any of the models of business
based on free software.
1.4.5. Quality management
The purpose of quality management is to ensure that the project meets the
needs for which it was initially designed. We must therefore plan, assure and
continuously monitor the quality of the project in accordance with these
needs.
Quality��management��in��free��software��projects
The features of quality management in free software projects are theoretically
the same as those of any other software project.
On the one hand, we need to consider quality from the user's point of view,
adopting the standards required in each case. And on the other, in the case
of projects in which we work with the free software community, whether
contributing to an existing project or creating a new one, we need to take
into account the quality of the code produced from the point of view of the
developer.
We will need to follow the recommendations on programming style, naming
Standard programming
styles
conventions, documentation, error logs and formats, languages, etc. With new
projects, it is a good idea to circulate these recommendations.
Remember that you should
follow the programming
styles that have already been
1.4.6. Human resources management
defined and accepted by the
community, such as the Java
Code Conventions or Linux C
kernel style.
The purpose of human resources management is to employ the individuals
participating in the project as efficiently as possible. The activities carried out
as part of this management include the organisational plan, hiring of new
employees and team development.
Human��resources��management��in��free��software��projects
The features of human resources management in free software projects are
theoretically the same as those of any other software project, but you should
bear in mind a few points.
GNUFDL " PID_00148382 33 Free software implementation, projects and companies
Most importantly, you will need to consider the possible participation of the
free software community and the effective contribution it may bring to the
project. It is generally a good idea to appoint somebody in charge of relations
with the free software communities connected to the project.
1.4.7. Communication management
The purpose of communication management is to ensure the correct
generation, collection, circulation, storage and elimination of project
information within set deadlines.
Communication��management��in��free��software��projects
The features of communication management in projects based on free
software are theoretically the same as those of any other software project. It is
very important to ensure the communication and circulation of information
within the project, particularly when collaborating with the free software
community. If you are not working with the free software community but
there is a possibility of releasing the code or the client would like access to
the latter, it is also important for the source code to be readable and well
documented.
The configuration and correct use of software forges or collaborative

We recommend defining rules that should be followed when drafting the
documentation, together with the tools that will be used for its automatic
generation.
1.4.8. Risk management
The purpose of risk management is to identify, analyse and respond to events
that could jeopardise the project plan in the form of delays and increased
costs.
These risks must be correctly identified and quantified, and have their
appropriate response mechanisms. A risk is always characterised by
uncertainty  since the event associated with the risk may or may not occur
GNUFDL " PID_00148382 34 Free software implementation, projects and companies
 and by loss  because if the event eventually does occur, it will result in
negative consequences or losses for the project. Thus, to be able to characterise
the risks, we need to evaluate their probability and associated losses correctly.
There are several risk classifications. In this initial approach, we can consider
the following three types of risk:
" Management risks, related to problems with scheduling, budgets and the
organisation of staff and resources.
" Technical risks, which jeopardise the quality and scheduling of the
project and pose obstacles to its development and implementation. The
most common technical risks concern potential problems with design,
implementation, verification and maintenance. They usually arise from
ambiguities in requirements and specifications and the use of outdated or
very new technologies.
" Business risks, which raise questions about the feasibility of the project.
For example, developing a project for too small a market or one that does
not mesh with the company's sales line.
Risk��management��in��free��software��projects
The features of risk management in free software projects are theoretically the
same as those of any other software project.
A classic example of risk in free software projects is the fear and uncertainty 
of both the organisation and users  regarding technological change on a new
and possibly unfamiliar platform.
It is useful to introduce communication and training methods at the start
of the project in order to cancel out any negative effects of the rejection of
technological change. It is good practice to earmark a time for presentation,
communication and user training that will be continued and built on
throughout implementation in order to provide an outline of free software
and of the specific applications and tools.
Another classic example of risk in free software projects are the possible legal
incompatibilities between free licences for the use of code development and
reuse.
It is wise to check at the start of the project that the licences applied to
the different parts of the code are coherent among themselves and that the
planned development will not generate incompatibilities. This check should
GNUFDL " PID_00148382 35 Free software implementation, projects and companies
be carried out before every release. It is good practice to keep a licence chart
indicating the licence under which each of the software packages is distributed
and the individual interactions between them.
1.4.9. Supply management
The purposes of supply management are to ensure that the materials and
resources needed to execute the project are available at the right time and in
the right place.
Supply��management��in��free��software��projects
The features of supply management in free software projects are theoretically
the same as those of any other software project.
The migration and implementation of a free software system is usually a good
time to renew equipment or to modify the structure of the organisation's
network. The project plan must therefore include orders of new equipment
and materials in order to take into account and prevent possible delays.
GNUFDL " PID_00148382 36 Free software implementation, projects and companies
2.Free software projects
A project is an organised, structured process of managing resources in order
to achieve a specific aim, usually strategic. While, in the first part, we looked
at the key aspects of the functional management of resources, this module
will focus on the stages that the project needs to complete in order to achieve
its aims.
We can generally define seven key stages in projects to implement free
software systems:
" Study of the current situation
" Study of the implementation requirements
" Analysis of free software solutions
" Formalisation of the proposal
" Development
" Implementation and migration
" User training, documentation and support
As we can see, these stages are the result of development of the phases
described in the first section of this unit and they apply specifically to free
software. Nonetheless, the development described is fairly generic and can be
applied to other implementation processes.
This section describes the life cycle of the project and outlines the process,
its stages and its relationship with the management of the project and the
resources allocated to it.
The subsequent seven sections will detail the stages of the project, linking and
expanding on the concepts introduced in the first part of this module.
2.1. Life cycle
This first section introduces the main methodological and functional
characteristics of the life cycle of the project in order to provide an outline
of the process.
The life cycle of the project links the methodical aspects, intrinsic to the
development of the implementation stages, to the functional management of
the project. Thus, the life cycle guides the execution of the various stages over
time and with the available resources.
By and large, the life cycle of a project has two main aims:

management of risks, see the
section on risk management in
the previous unit.
The project life cycle can be used to monitor the evolution of the stages, the
schedule of execution and the financial cost of the project. The management
of this cycle is dynamic, so decisions to modify and adapt can be taken as time
passes in order to readjust our estimates of the initial parameters on the basis
of actual events.
Broadly speaking, the life cycle has four key areas: the project, the stages,
execution and the results.
2.1.1. The project

section on the management
of free software projects in the
previous unit.
Minimising the time or resources spent on a project will usually minimise the
aims that can be met or affect quality, and vice versa. In contrast, minimising
project time while maintaining its aims requires us to increase the resources
allocated to it. Project management seeks to find the most acceptable balance
between these three elements.
In all events, changes in the relationship between these three elements have
direct financial repercussions that will need to be assumed in the event that
we are updating. The management of the project also has a financial cost from
the point at which the project begins (when it is decided to allocate time of
one or more staff to take on this management).
The main factors influencing the time and resources required to conclude
a project normally refer to the size and complexity of the system to be
implemented. In this sense, the features of free software tend to reduce the
time and financial costs of the project:
" Variety��of��applications. The maturity of the free software market means
the availability of a wide variety of direct implementation products that
are reliable, consistent and secure.
" Licence��cost. Free software is usually obtainable without licence costs and
can be downloaded directly from the official website or from other public
pools.
GNUFDL " PID_00148382 38 Free software implementation, projects and companies
" Source��code��modification. The open nature of the source code allows the
expansion, modification and adaptation of products that would require
a new development to evolve the product if proprietary licence models
were applicable.
It is important to note that free software also helps to reduce the overall risk of
the project because it provides the freedom to view, use and modify the source
code, allowing evaluation and assessment of all aspects of the application in
depth.
Additionally, the project can be managed and executed internally or outside
the organisation. Broadly speaking, we can differentiate between two main
cases:
" Insourcing: this is the case when an organisation develops a project
launched as a result of a strategic action. In other words, the organisation's
IT department manages and executes the project.
(5)
" Outsourcing: this definition applies when an organisation delegates the

that manages and executes projects5. In other words, the organisation
reduces its direct exposure to the development of the project.
Thus, the format of the project development will take into account
the capacity and experience of the organisation that must assume the
development of the project, the associated costs, the implementation schedule
and the specialisation of the external organisations present in the project.
Lastly, the project is evaluated in terms of tangible and intangible benefits.
Here we can come across cases in which a surcharge for time or financial costs
may be feasible in order to obtain the intangible benefits  usually strategic 
required by the organisation. For example, improving corporate image with
the use and diffusion of free software and the free philosophy.
2.1.2. The stages
The project life cycle is implemented in the form of successive and possibly
simultaneous stages. Each stage meets a clear, set aim in a scenario related to
the project, with the result that, taken together, these stages meet the aims
of the project.
GNUFDL " PID_00148382 39 Free software implementation, projects and companies
Broadly speaking, a stage can be considered a process that receives
inputs and produces certain outputs. In other words, it requires a prior
scenario with information about the environment in order to produce
certain results.
Hence, a relationship is established between the diverse stages of the project,
since each stage achieves part of the global aims. This relationship usually
takes two forms:
" Dependence: between two stages indicates that a stage requires the result
of the execution of the other in order to complete its task. This means that
the stages must be executed sequentially over time: the stage generating
the results first, followed by the stage that uses these results. For example,
the development stage requires the study and analysis of the systems
implementation requirements in order to complete its task.
" Independence: between two stages indicates that two stages have no
direct relationship with each other and no specific prerequisite. This
means that the stages can be executed simultaneously, though more
resources may be required. For example, the system implementation stage
can be executed at the same time as the user training stage.
Moreover, the stages also allow for a distributed execution of the project,
that is, one or more stages are assigned to different teams, either internal or
external to the organisation (insourcing and outsourcing).
Extreme cases may arise if several stages are assigned to different external
organisations. It will all depend on the characteristics of the project, the
specialisation of the external organisations and the associated costs.
All this highlights the importance of deliverables between stages. The
importance of documenting results in the form of deliverables is threefold:
" Since the documentation of the stage summarises its development and
results,
" since the result of the stage is important for the stages that depend on it,
and
" since the result of the stage is a result that can be evaluated for the
development of the project.
The connotations of the internal or external execution of each stage highlight
the importance of deliverables. It should be noted too that their importance
is proportional to the complexity and size of the project.
GNUFDL " PID_00148382 40 Free software implementation, projects and companies
2.1.3. Execution
Execution of the project will begin in accordance with the initial proposed
planning, with careful monitoring by the organisation in which the system is
to be implemented. By and large, three key parameters need to be monitored:
" Time. Time monitoring and management are essential for project
monitoring because any change to this parameter will have direct
financial consequences. It is also particularly important for the sequencing
of the different stages, particularly if they are assigned to different teams.
" Outsourcing. Monitoring the outsourcing of the stages or perhaps the
entire project is important if we are to ensure that the work and its results
meet the aims of the project and the organisation. We need to pay close
attention to the monitoring and quality of deliverables and make sure that
we follow the schedule correctly.
" Quality. The quality control of the tasks completed during execution
of the project will have a major impact on the end quality of the
implementation. Communication and the transfer of information within
the team developing the project and in the organisation itself must also
be qualitative in order to guarantee the aims of efficiency and efficacy.
In practice, the execution of the stages can be delayed for a number of
reasons that may or may not be linked to the project and its management.
Examples of these include a lack of synchronisation in the delivery times of
the necessary material, the temporary absence of analysts or programmers and
the complexity of a development not initially envisaged. Delays usually have
financial consequences.
When a delay occurs, two types of decision can be taken:
" Firstly, the delay can be worked into execution of the stage, concluding
it and accepting a delay in all stages that depend on it and, as a result,
the overall project.
" Secondly, a project delay may be considered unacceptable and more
resources are allocated to one or more stages in order to keep up the pace.
Nonetheless, the allocation of more resources does not always lead to
production improvements proportional to the resources earmarked.
Delays should not generally have a direct effect on stages executed at the same
time as the stage that has been delayed. However, it may be worth considering
a schedule adjustment to take into account the delay affecting other stages.
GNUFDL " PID_00148382 41 Free software implementation, projects and companies
For example, if implementation of the system is postponed because of an
excessive delay in the reception of materials, we could consider the option
of delaying the user training phase until implementation. This would avoid
a gap between user training and application of their knowledge of the newly
implemented system.
2.1.4. Results
The results of the life cycle of a project should be directly related to the
strategic aims of the project and the organisation. Life cycle in itself is
merely a methodical and rigorous way of coming up with a solution
for a given problem by dividing the inherent complexity of the project
into different stages.
To an extent, life cycle is one way of reducing the overall risk of the project.
The execution of the stages as successive fine-tuning periods for solving
problems contributes to the gradual adaptation and solution of problems that
can be highly complex.
We need to consider the importance of the project management team, which
plans and coordinates the project to ensure that it is concluded successfully.
Management is a dynamic task that must help to reconcile the differences
between planning and the reality of the project during its execution.
The results of a systems implementation project are generally grouped into
the following areas:
" Organisation. For the organisation, the project needs to meet the
expectations of the strategic action from which it derives. We need
to stress here the qualitative operation of the system, its integration
with the organisation's methodology, user adaptation and competitive
improvements to the organisation.
" System. The system needs to meet all of the aims and expectations of
the organisation and its operation needs to meet the aims of the strategic
action of the organisation. The system and its interaction with direct
and indirect users must meet these aims qualitatively, offering functional
efficiency and efficacy.
" Users. One of the aims of the system is to provide technological support
to the organisation's operation through its users. The importance of the
inclusion of users in the implementation project is strategic, since without
their participation in the process and their acceptance of the system,
GNUFDL " PID_00148382 42 Free software implementation, projects and companies
implementation could prove problematic or unfeasible and have financial
repercussions.
" Documentation. As with any project, documentation is crucial to the
quality of the implemented system for its current integration and future
evolution. From deliverable documents between stages to the final
documentation or user manuals, all of these materials are crucial to the
maintenance and support of the system.
" Support. The system must have a support team in place from the start
of the project, although it is particularly important in the development,
implementation and user training stages. The team needs to guarantee
interaction and communication between all those involved in the project
during and after implementation, acting as a support team for ongoing

Systems analysis covers two complementary aspects:

and procedural perspective.
Case study
Case studies are a scientific method that allows us to explore an object or circumstance in
depth through the use of empirical strategies in order to understand the object of study.
It is usually used in the initial exploration and in combination with other techniques
such as the quantitative approach (statistics related).

the organisation's strategy, with the ensuing financial repercussions6.
Although this section describes the features of the initial study for a system
that has already been implemented, this structure is equally applicable to
newly implemented projects if we transfer the object of study to the scope
of the organisation, the current and past markets, future technological trends
and similar projects begun previously.
This first stage of the project may also bear no direct relationship with
free software, since the aim is to analyse and evaluate the implemented
system or the current market, regardless of the form of implantation or trend,
respectively.
Broadly speaking, we can divide systems analysis into three main phases:
identification of the system, preparation or development of the case study and
the final evaluation.
2.2.1. Identification of the system
The purpose of identifying the system is to define the object, scope and aims of
the study. The definition of these parameters is directly related to the strategic
action on which the project is based and must allow us to set up the scenario
for evaluation.
It is important to remember that a system already in place is not simply a set
of technological parts; it is also a series of features, methods and procedures
that have a direct impact on users and the organisation in general.
Hence, the study scope must cover the technological aspects of the
implementation, the features currently covered by the system, the procedures
and methods of action deriving from its interaction with the organisation's
operation and the impact on the use of the direct and indirect users of the
system.
We need to determine two key aspects of these parameters:

extraction techniques vary widely.
Quantitative and qualitative data
Quantitative data are numerical variables that quantify characteristics or attributes. For
example, the number of active users in the system per unit of time.
Qualitative data are variables that differentiate between characteristics or attributes but
do not quantify them. For example, the colour combination of an application's user
interface.
The result of this phase is a working document indicating the object, scope
and aims of the study, along with a list of the data that must be obtained and
the source of this information.
2.2.2. Case study development
This phase is used essentially to collate all of the important study data
indicated in the system identification phase.
In practice, information can be gathered from a range of sources: historical
documents, detailed interviews, results of technological audits, performance
counter tools, the documentation of previous projects, technological
specifications and even issue reports.
As we collect data, we may come across interesting aspects that were not
considered in the system identification phase. In all events, data collection
needs to be rigorous and meet the criteria on structure and organisation.
Nonetheless, we can differentiate between two generic groups in data
collection:
" Quantitative��data. This type of data is usually collected directly from
technological media. The implemented system may have counters for
performance, transactions, capacity, volume, etc., which can generate
interesting statistical results, as in the case of time or cost units.
" Qualitative��data. This type of data is usually collected from written
documents, meetings or staff interviews. The procedure for obtaining
information from interviews and meetings is crucial here, because they
must be painstakingly prepared and conducted if we are to obtain quality
information.
GNUFDL " PID_00148382 45 Free software implementation, projects and companies
It is very important to use a methodical process to obtain both quantitative
and qualitative data, since the system is a support tool for staff and the
organisation itself. All information is beneficial when it comes to assessing
and evaluating the system.
This phase usually marks the beginning of the development of the hardware

The end format of the case is usually an investigative report in which all of
the aspects dealt with above are organised and evaluated. The report must
back up the data and results it describes, relating them to one another and the
definition of the project and seeking out possible relationships of dependence
or independence.
Depending on the type of information described, it may be convenient to use
statistical results, tables, graphs and charts, and generally anything that will
help with the description, understanding and evaluation of the data included
in the report.

study of the current system from a strategic point of view. If the features of
the project require, we can produce SWOT tables by classifying the various
features of the system according to the result of their evaluation, such as if the
current system's hardware is a weakness for carrying out the strategic action
successfully.
2.2.3. Final evaluation
The final evaluation of the system is the first control point of the project and
its aim is to determine the feasibility of the current system in the light of the
organisation's strategic actions and hence, evaluate the need to continue with
the project.
Generally speaking, there are four large groups of features that we need to
consider:
" Operating. These relate to the functional interaction of the users with the
implemented system, ergonomics, performance, efficiency, efficacy and
usefulness.
" Organisational. These concern the methods and procedures generated by
the implemented system, together with their benefits and disadvantages
for the organisation.
GNUFDL " PID_00148382 46 Free software implementation, projects and companies
" Functional. These relate to the efficiency and efficacy of the tasks
carried out by the implemented system, in addition to scope, reliability,
performance and malfunctions.
" Legal��and��financial. These relate to the cost of the implemented system
and its legalisation, covering aspects such as maintenance, licensing and
system administration.
Evaluation of the system can bring us to three main groups of conclusions:
" The��system��is��feasible. The study and evaluation conclude that the
current system is ready to take on the strategic actions of the organisation.
These conclusions are usually drawn in cases where a study has been
conducted to find out the status of a large and/or complex system whose
evolution could be difficult to gauge on a superficial level.
If the current system obtains a positive evaluation, the implementation
project must be cancelled because there are no indications that a new
implementation is required.
" The��system��is��partially��feasible. The study and evaluation conclude that
the current system needs minor updates before it can take on the strategic
actions of the organisation. These changes usually involve updating or
changing a small series of elements, such as replacing devices or updating
software.
A partially positive evaluation of the current system requires continuing
with the implementation project but it is convenient to revise the aims
and scope in order to adapt them to the needs detected.
" The��system��is��unfeasible. The study and evaluation conclude that the
current system cannot assume the strategic actions of the organisation.
This type of conclusion is usually drawn in cases of migration from older
systems that are unreliable or perform poorly and hence need to be
completely updated.
A negative evaluation of the current system tells us that we should
continue with the project to implement a new system. It may be necessary
to revise the aims and scope of the project because replacing the current
system may require more resources than those initially envisaged.
Both the report on the analysis and the final evaluation of the current system
are submitted to the organisation by the project monitoring committee. The
final decision on whether or not to continue with the project is usually made
by the management of the organisation.
The result of this stage is twofold:
GNUFDL " PID_00148382 47 Free software implementation, projects and companies
" Firstly, we obtain a comprehensive report on the current status of the
system, highlighting the main features of the system from the point of
view of the organisation's strategy.
" And secondly, the organisation makes a decision as to whether or not to
continue with the project and any actions required to adapt the system
to the latter's strategy.
2.3. Study of the implementation requirements
This section will define the study of systems implementation requirements
and describe its main characteristics and special features. It will detail the
various phases of the study, the main factors influencing its development and
the results that it should produce.
The study of the system requirements is a process requiring a
methodological analysis of the problems that need to be solved.
There are two main aims to the requirements study:
" To��define��the��implementation. Requirements studies allow us to detail
all the features that the system to be implemented must have and
permit. To a certain extent, they define the specific, functional aims of
implementation.
" To��reduce��risks. Requirements studies also allow us to reduce the risk
of the project and its management by specifying and progressively
fine-tuning the characteristics of the solution to be implemented.
Requirements studies for systems implementation projects usually require a
great deal of effort for two main reasons:
" Firstly, because it can be difficult to specify and methodologically structure
the ideas and expectations of users and the managers of the organisation
regarding the new system, bearing in mind that user requirements can
evolve over time.
(8)
" And secondly, because they are crucial to the subsequent development of

in later stages will affect the timing and financial aspects of the project or
generate unplanned extra costs that could jeopardise completion of the
project8.
GNUFDL " PID_00148382 48 Free software implementation, projects and companies
A requirement is a feature that the new system needs to have. In other
words, it is an attribute that must allow the system to meet the set aims.
Requirements are usually written as text but can take the form of tables
and charts if these help to clarify and specify the aim.
In general, we can define four different types of requirement:
" Strategic��policy. Requirements linked to the organisation's strategic
policy cover general aspects of the project, its management, outcome, or
the approach to adopt. These include corporate ethics and image or the
traditional attributes of the organisation.
" Methods��and��procedures. The implementation of a new system is usually
a good time to update and improve the methods and processes of
the organisation and/or system. Besides a thorough revision of current
procedures, we will also need to bear in mind the specification of future
methods and procedures resulting from new aims or features that the new
system will need to encompass.
" Operation��of��the��system. The operating requirements of the system
derive from the interaction of users with the system. We will need
to distinguish between functional and non-functional requirements:
functional requirements correspond to specific actions that the system
will need to execute, whereas non-functional requirements correspond to
limitations or restrictions while executing actions, which allow the actions
to be linked to the methods and procedures.
" Key��factors��and��priorities. Most systems have a specific number
of basic elements that form part of the core of the system. In
new implementations, we need to give preference or priority to the
components considered essential for the operation of the system and the
organisation; other components not considered essential can be given a
lower priority.
The requirement collection stage is not exclusive to free software because free
software systems implementation must meet the same requirements and aims
as any other type of implementation.
Broadly speaking, we can divide the study of system requirements into five
main phases: identification and definition, specification and structuring,
verification, validation and the final evaluation.
GNUFDL " PID_00148382 49 Free software implementation, projects and companies
2.3.1. Identification and definition

implementation projects.
The requirements study stage uses documentary information from the analysis
of the current status stage, so part of the task of pinpointing the problems has
already been completed.
We will need to identify the resources and elements from the organisation
that are directly or indirectly involved and define the scope of the problems
for the organisation and for those resources and elements that are directly
and indirectly involved, whether human, material, functional, organisational,
procedural or technological. All these elements will usually allow us to recover
vital information for defining the new system, which we can use, together
with the report on the current status, to establish a corpus of knowledge for
making decisions.
The direction in which the market is heading is also important when it
comes to defining requirements. Familiarity with the features of similar
systems, organisations from the same sector, recent innovations and the
future trends of the project theme can all be helpful when it comes to
specifying, proposing, evaluating and understanding the requests of users and
organisation managers.
The result of this first phase is usually presented in a working document with
a detailed definition of the aim and scope of the project, a list of the elements
to consider, sources of internal information on the organisation and a list
of elements or market trends that may contain relevant information for the
project.
2.3.2. Specification and structuring
The aim of the specification and structuring phase is to collect relevant
data on all of the elements indicated above and to organise them using
methodological criteria to create a reliable corpus of knowledge that accurately
represents the reality.
This phase is based on the working document produced in the previous phase,
providing an initial outline of the elements and sources of information that
may contain relevant information for the project. Nonetheless, the practical
development of the study may lead us to consider new sources of information
and new aspects of relevance to the project that were not taken into account
in the previous phase. Deadlines permitting, we should try to investigate all
of the details that may appear.
GNUFDL " PID_00148382 50 Free software implementation, projects and companies
We can identify two tasks in the development of this phase:
" Collection�� and�� specification. This task attempts to resolve the
functionalities of the system. In other words, what the system has to do,
not how it has to do it. Some information sources tend to focus on how
actions should be done instead of determining the specific features of the
task itself.
" Structuring�� and�� organisation. This involves organising data
methodically and comprehensibly. It may be useful to prioritise certain
requirements over others, in accordance with the elements of the system
required for its operation.
As with the study of the current status, data collection may respond to
quantitative or qualitative criteria:
" Quantitative��data. These usually come from technological media and
can be bulk processed in order to obtain statistical results to verify and
justify qualitative data and to model and extrapolate results to new
functionalities.
" Qualitative��data. These are usually taken from interviews and meetings
with those involved and provide us with functional and non-functional
results regarding the system and the procedures and methods affected by
the project.
Systems implementation requirements relate to the basic elements of the
whole system, such as the hardware, software, infrastructure, staff, procedures,
functionalities and even languages, documentation, formats and standards.
Requirements are usually presented as text, organised according to the
characteristics of the project, system and the special features of the
requirements themselves. Tables, graphs and charts can also be used to
improve the definition, arguments and evaluation of the ideas covered.
The result of this phase usually takes the form of a working document
that describes all of the requirements, organised, structured and reasoned in
accordance with the ideas of the project. The clarity and precision of this
document is crucial for the entire project, since all subsequent development
and the organisation's acceptance of the terms of the final implementation
both depend on it.
GNUFDL " PID_00148382 51 Free software implementation, projects and companies
2.3.3. Verification
The requirements verification phase evaluates the requirements contained
and described in the previous phases and assesses them in the context of the
system's coherence and the aims of the organisation.
This phase uses the working document from the previous phase, which
methodically organises the requirements obtained in the study.
The formal verification of the requirements can be split into two main
processes:
" Technological��analysis. The technological analysis of requirements
is a process aimed at analysing and concluding that all of the
requirements complement one another and form a logical system whose
implementation is feasible.
Antagonistic requirements resulting from the diversity of information
sources are usually detected in this phase. This conflict can be resolved
by checking the other characteristics covered by the requirements
and/or validating the options with those directly involved or with the
organisation.
" Functional��analysis. The functional analysis of the requirements is a
process aimed at analysing and concluding that the system deriving from
implementation of the requirements meets the requirements and aims of
the project and the organisation.
In this phase, we can detect inaccurate assumptions in the requirements,
which can contradict the aims of the project. The conflict can be resolved
by a review and consultation of the problematic aspects with those directly
involved and/or with the organisation.
Requirements verification is a fundamentally technological and
methodological process that analyses the coherence and feasibility of the
future implementation and introduction of the system defined in the
requirements.
It can be interesting to have a number of people participate in the review of the
requirements. Different perspectives can help pinpoint and solve any errors
or shortcomings more effectively.
The review can also stimulate the appearance of new issues or situations not
previously considered, which may generate a loop between the collection of
requirements and their verification until convergence and coherence have
been established in the results (a similar process to top-down methodology).
GNUFDL " PID_00148382 52 Free software implementation, projects and companies
Top-down methodology
Top-down methodology takes the general definition of a problem and creates a loop by
specifying and refining each item until a sufficient level of detail is considered to have
been reached. The result is usually displayed as a process tree.
The result of this phase is that the working document with the requirements,
created in the previous phase, is updated. This updating has allowed a
detailed review of the concepts of implementation and the identification and
resolution of any errors in the initial requirements.
2.3.4. Validation
The requirements validation phase is designed for reaching an agreement
on the requirements of implementation of the new system  following the
study  with the organisation. Agreeing on the requirements is crucial to the
contractual formalisation of the implementation of the system.
This phase requires the active participation of the organisation, which must
conduct a thorough analysis of the requirements proposal resulting from
the previous phases. The transfer of information between the two groups
is essential because the characteristics of the implementation of the system
depend on the understanding of the requirements study.
The internal working document containing the requirements may not be
entirely appropriate for presentation to the project's monitoring committee.
In this case, it may be necessary to create new documents or presentations
to transmit the information in a clearer and more effective way, using charts
and diagrams.
The organisation's validation of the requirements may conclude with new
revisions of the requirements. These revisions or adjustments usually involve
the addition of new functionalities to the system by the organisation that were
not initially planned in the project.
Nonetheless, these revisions cannot continue indefinitely because they could
have a direct impact on the feasibility of the project and its implementation
schedule, not to mention the financial implications of the increase in the
number of requirements to implement.
The result of this phase is closely related to the final evaluation phase of
the systems requirements study. It usually generates the last revision of the
working document with the requirements of the new system, agreed and
validated by the organisation and the team that conducted the requirements
study.
GNUFDL " PID_00148382 53 Free software implementation, projects and companies
2.3.5. Final evaluation
The final evaluation of the requirements study is the second control point
of the project, the aim of which is to determine the feasibility of the
implementation project in the light of the requirements of the new system
and hence, the need to continue with the project.
This phase is closely related to the validation of the requirements, since the
main working document represents the last definition of the requirements for
implementation of the system, agreed on by the organisation. The validation
and final evaluation phases may be merged for making decisions regarding
the need to continue with the project.
The feasibility of the system requirements is evaluated by taking into account
their suitability for the current system, the organisation and the strategic
action that launched the project. The requirements study is the first formal
step towards the new system and early estimates of the volume and cost of
the changes.
In a way, the evaluation of the requirements is similar to the evaluation of the
current status that we looked at in the first section, which bases its assessment
on financial, technological, functional and legal aspects. We can also evaluate
other aspects relating to the strategy of the organisation, such as the latter's
capacity to evolve, the intangible benefits of the change, management quality
and corporate ethics.
The evaluation of the proposed requirements for the new system can lead to
three main groups of conclusions:
" The��project��is��unfeasible. The evaluation of the requirements of the new
system by the organisation concludes that implementation of the new
system is unfeasible and the project is abandoned.
There may be a number of reasons for reaching this conclusion, some of
which could even be outside the scope of the project. This outcome is
usually related to economics, financing, competition or the abandoning
of the strategy that launched the project.

implemented.
This outcome is usually related to economics and financing. In some cases,
partial implementation can be carried out progressively or in stages9. In
these cases, it is important to introduce guarantees to ensure cohesion
between the different implementations over time.
GNUFDL " PID_00148382 54 Free software implementation, projects and companies
" The��project��is��feasible. The organisation has made a positive evaluation of
the requirements of the new system and the project will continue without
major limitations or restrictions that could affect the basic definition of
the project.
The result of this stage is twofold:
" Firstly, we obtain a full report on the requirements of the new system to
implement, validated by the team and the organisation.
" And secondly, the organisation makes a decision as to whether or not to
continue with the project and on the scope of the implementation of the
new system.
2.4. Analysis of free software solutions
This section will define the analysis of solutions for the implementation
project and describe its main characteristics and special features. It will detail
the various phases of the analysis, the factors influencing its development and
the results that this stage should generate.
Solutions analysis is a process whereby the various technological
options available are analysed methodically and rigorously in line with
the project requirements.
This analysis has three complementary aims:
" To��know��the��market. The analysis of solutions allows us to study and
evaluate the current market situation in terms of the definition, scope
and aims of the implementation project. The variety of solutions currently
available means that an deep, careful analysis is required.
" To��adapt��the��solution. The analysis allows us to select the solutions that
best fit the problems of the project and the implementation of the system.
Moreover, the open nature of the source code inherent to free software
allows for the fine-tuning and final adaptation of the chosen solutions in
the form of derivative products.
" To��reduce��risks. The analysis of solutions allows us to reduce the risk
of the project and the implementation of the system because the study
allows us to adapt the solution and control the main repercussions of its
implementation.
GNUFDL " PID_00148382 55 Free software implementation, projects and companies
With free software, the solutions analysis stage takes place in a scenario limited
by two main conditions:
" Project��typology. The project typology, the characteristics and the scope
of the system to be implemented will determine the scope of the search
for and analysis of possible solutions, together with the feasibility of the
various proposals.
" Analysis��of��requirements. The analysis of system requirements must
determine the functional and operating behaviour of the solution in terms
of the project aims.
As we could expect based on what has gone before, this stage uses the
documents on the definition, aims and scope of the project and on the system
requirements agreed with the organisation. The report on the evaluation
of the current situation can also be useful here because it indicates the
characteristics, special features, and conclusions on the viability of the current
system. All of this must help us to focus on the characteristics of the analysis.
This stage focuses mainly on the strength and diversification of the market's
current supply of free software. The search for and selection of free solutions
that meet the requirements is essential for the implementation project.
Hence, our analysis must reflect the competitive attributes of free software in
comparison to private solutions, with a special emphasis on freedoms of use
and source code adaptation.
Broadly speaking, the free software solutions analysis stage can be divided into
three main phases: the search for solutions, the analysis and assessment of
candidates, and the final evaluation.
2.4.1. Search for solutions
This first search phase is aimed at identifying solutions whose implementation
in the framework of the project is feasible. It is used to make an initial selection
of systems with a similar aim to those of the project.
Free software is a valid and viable option for systems implementation since it
offers a wide range of freedoms of use, operation, access and modification of
source code, and licensing of derivatives.
These features not only allow them to be used freely by organisations
and private individuals, they also permit independence from proprietary
providers, savings on licences and royalties, learning from the original source
code, monitoring of obsolescence with guaranteed product maintenance,
quality and reliability, and guaranteed security, privacy, interoperability and
software convergence.
GNUFDL " PID_00148382 56 Free software implementation, projects and companies
Free software implementation can traditionally be divided into two main
areas:

licence and other requirements specific to the product, such as ergonomics
of use, execution requirements and the main functionalities.
If there is no single solution for the problems of the project and we need
to split it into different individual solutions, the document can be organised
into categories by typology (for example, operating systems or office suites)
or by function (such as a database server with a web interface for access and
programming).
A SWOT table is also sometimes included for each of the options found.
This table is very important in meetings and executive decision-making, and
its aim is to identify and summarise the main characteristics and specific
advantages and disadvantages of adoption of these options.
2.4.2. Analysis and assessment of candidates
The aim of the analysis and assessment of candidates phase is to identify the
solutions most suited to the project and the organisation and to the special
features of the development, implementation and migration.
This phase uses the document from the previous phase, which lists the most
suitable current solutions for the project and details their main characteristics.
The purpose is to methodically and carefully select the best candidates for
implementation from among the diverse alternatives identified.
A series of technological parameters directly related to the project,
organisation and implementation process are usually analysed, considered
and evaluated. The individual assessments produce an organised classification
that will determine how well suited each solution is to the implementation
project.
We can generally use the following parameters to assess and evaluate a
solution:
" Project��and��organisation. We must assess its adaptation to the project
aims, the organisation, the definition of methods and procedures, the
ethics and traditional standards of the organisation and the strategic
action that launched the project.
" System��and��interoperability. Here we need to assess how well it meets
the needs of the system and confirm its guaranteed operation with current
or future hardware, software and network resources, the feasibility of
the methods and procedures, implementation of the strategic action,
interoperability with existing systems and standards in the organisation
and the possibilities for future expansion and evolution.
GNUFDL " PID_00148382 58 Free software implementation, projects and companies
" Functionality��and��ergonomics. We need to assess how well it meets the
functional and operating needs of the project and the organisation, and
confirm the ergonomics of its use and implementation of the methods
and procedures with guaranteed operation and that it will meet the
expectations of the users and the organisation.
" Efficiency��and��performance. We need to assess whether it can guarantee
efficient operation at all times, the use and performance of allocated
resources and maintenance of a suitable balance between resources and
performance over time, to allow evolution.
" Efficacy��and��reliability. We need to assess whether it guarantees
performance of the functions set down in the project aims, maintains
functional compliance with the aims at all times, preserves the balance
between resources and compliance over time and that allows evolution.
" Implementation��and��migration. We need to consider how well suited
it is to the system implementation process and confirm that it allows
efficient and effective migration from an earlier system, minimises the
consequences of impact on the everyday operation of the organisation
and that it guarantees tools for the support, training and adaptation of
users and any other systems currently in place.
" Maintenance��and��management. We must assess whether it will equip the
system with management and configuration tools adapted to the project
aims, minimise physical and logical maintenance operations, guarantee
a balance between operation and maintenance over time, and allow
evolution.
" Support��and��commitment. We must evaluate whether the support and
monitoring of its creators for the system and its users are guaranteed,
and whether it contributes to the community commitment to evolution,
future improvements, problem solving and generally all aspects that could
cause the system to become obsolete.
" Licences. We must evaluate whether it guarantees compliance with the
legislation in force, establishes a scenario for use and operation, allows
a clear and effective distinction to be made concerning actions that can
be performed with the system and specifies the licences for any products
derived from it.
" Economics. We need to evaluate how it adapts to the economy of the
organisation, the planned project financing, the costs of management,
maintenance and its efficient and effective operation throughout the
expected life of the system and the costs of training and educating the
users of the system.
GNUFDL " PID_00148382 59 Free software implementation, projects and companies
As we can see from the above list, the parameters seek to assess candidates
in different areas (technological, strategic, operating, financial, etc.), in
order to detail, analyse and evaluate the impact of implementation on the
organisation.
The result of this phase is a document that numerically classifies and considers
the various candidates (possibly by category), organising the solutions
according to how well they adapt to the project and the organisation.
Given that different solutions could obtain the same technical score, it may
be necessary to conduct another study on these alternatives that, despite
differing in their characteristics, have similar degrees of adaptation to the
project. In these cases, it may be useful to draw up a SWOT table for each
solution in order to reveal the differences that could help us to make our final
choice.
2.4.3. Final evaluation
The final evaluation of the analysis of free software solutions is the third
control point of the project and its purpose is to determine the development
of the implementation project, i.e. the form of the project and its final
implementation.
This phase uses the documents from the previous phase, which classify the
existing solutions based on how suited they are to the project, and the
summaries of technical features and/or SWOT tables analysing them in detail.
This phase has two main aims:
" Final��selection��of��candidates. Although the previous phase indirectly
proposes the most appropriate solutions for the project and
implementation (by scoring and classification), it may also be necessary
to evaluate the overall integration of all of the solutions.
" Development��of��the��project. The choice of the solutions meeting the
project requirements will have direct consequences on its development,
such as its cost in terms of time and financial resources.
Remember that the components of the system will not be separate from one
another, so the best solutions will be those that generate a stable and operative
system besides meeting the requirements of the project.
GNUFDL " PID_00148382 60 Free software implementation, projects and companies

In some cases, it may be useful to carry out integration tests to determine

the integration of solutions that have obtained high scores in their respective
categories does not necessarily guarantee an overall performance of the same
level16.
The choice of solutions will generate adaptations in the project, particularly
during the development phase. Overall, we can consider three different types
of implementation:
" Direct��implementation. Solutions most suited to the needs of the project

functionalities of the solution do not automatically rule out adoption.
" Evolution��of��the��solution. The solutions most suited to the requirements
of the project and the organisation can only reveal significant differences
at certain points. Their adoption requires an evolution of the source code
to adapt the possible shortcomings of the original solution in the event
of problems with the system.
The freedoms allowed by free software make it a valid and viable option
in practice, while the proprietary software alternative may require a
completely new development, with the ensuing financial implications.
" New��development. There are no solutions that adapt sufficiently to
the problems of the project and the organisation, so a completely new
development is required to solve them.
These cases may occur in systems with very specialised requirements, such
as robotics. In exceptional cases, proprietary solutions may not exist in
the usual marketing channels.
In all events, the freedom for studying, analysing and reusing the source
code of free software allows us to improve the quality, efficiency and
efficacy of the new development and cut associated costs.
The evaluation of free software solutions can lead us to three main types of
conclusion:

the project are not insurmountable17.
" Feasible��project��subject��to��conditions. The project is feasible but the

GNUFDL " PID_00148382 61 Free software implementation, projects and companies
Time and money implications will be dictated by the scope of the process,
which will be at its largest when a completely new development is
required.
" The��project��is��unfeasible. Although it is not usual to abandon the project
at this stage, the organisation can sometimes decide not to continue with
it. For example, if financing for a specific development is not available or
if the organisation changes strategy.
The result of this stage is twofold:
" On the one hand, we obtain free software solutions adapted to the
requirements of the project and the organisation.
" And on the other, we obtain a preliminary evaluation of the costs involved
at the development stage of the project (direct implementation or the need
for further development).
2.5. Formalisation of the proposal
This section will define the formalisation of the project implementation
proposal and describe its main characteristics and special features. It will
detail the various phases of the process, the main factors influencing its
development and the results that this stage should generate.
The formalisation of the proposal is the stage of the project in which
we detail, specify and link all of the results obtained in the early
methodological phases of the project  called design stages  with the
aim of putting forward a formal solution to the problems associated
with implementing systems in the organisation.
This stage has three specific aims:
" To��characterise��the��project. Formalisation of the proposal collates,
clarifies and lists all of the results from the initial design stages of systems
implementation. The result of this stage should serve as a guide for the
subsequent development of the implementation, hence it is a key part of
the project.
" To��obtain��validation��from��the��organisation. The formalisation of
the project also serves to present the implementation project to the
organisation, which must then evaluate it. The resulting evaluation will
determine the project's future, viability, development and execution.
GNUFDL " PID_00148382 62 Free software implementation, projects and companies
" To��reduce��risks. Formalising the proposal allows us to reduce the risk of
the project and implementation of the system, and delimit the scenario
of the project's evolution by detailing solutions and the development of
the implementation.
This stage is related to the functional management of the project because it
allows us to detail aspects of project planning such as management of time,
resources and project costs using the information obtained from the results
of the previous stages.
Overall, the proposal needs to cover two main aspects:
" Methodological��aspects. Methodological aspects refer to the results of the
analysis and systems implementation design stages that we have seen in
this unit. Specifically, these are analysis of the current system, analysis of
requirements and analysis of free software solutions. The aim here is to
detail the characteristics of the system to be implemented using a rigorous
and methodical process.
" Management��aspects. Management aspects cover the special features of

From the preceding paragraphs, we can conclude that communication and
collaboration with the organisation is important if we are to convey all of the
information regarding the project correctly. By and large, we can identify two
main aspects of the information that need to be conveyed:
" The��project. Understanding of the project, the results obtained from the
analysis and the solution most suited to the project characteristics. The
relationship between the project proposals and the strategic action of the
organisation must be clear.
" Free��software. Understanding of the use of free software, its philosophical
basis and the features of its licences, together with the special features of
the solutions proposed and the benefits obtained by the organisation.
Broadly speaking, we can divide the formalisation of the proposal into four
main phases: drafting, design, presentation and the final evaluation.
GNUFDL " PID_00148382 63 Free software implementation, projects and companies
2.5.1. Drafting of the proposal
This first phase of the formalisation of the proposal is designed to recover all
of the information that can be incorporated into the proposed solution. Here,
we should obtain the documents resulting from the various stages of study,
analysis and project planning.
One of the main aims of this first phase is to generate advanced results from
the initial data. In other words, we should create summaries, diagrams, tables,
charts and graphs to clarify the concepts in the technical documents drawn
up throughout the project.
Another result of this phase is the updating of the project planning using the
information contained in diverse analytical documents. The most important
aspects for the organisation are usually:

options. In these cases, it may be useful to evaluate and consider each of
the alternatives presented.
This phase generates a series of documents with results on two main aspects:
" Firstly, a set of references to technical analysis documents from the design
stages and diverse advanced results and information relating to the project
and free software.
" And secondly, an update to the project management planning, which
includes all aspects deriving from the analysis and design stages, shaping
continuance of the project.
2.5.2. Design of the proposal
The design phase of the proposal is used to draw up all documents
and presentations that must be submitted to the organisation and which
summarise the work carried out in the study and analysis stages of the systems
implementation project.
This phase uses the documents from the previous phase, with references to
technical documents, information on the project and free software, advanced
results and updates to scheduling and financial planning. The aim is to
structure, organise and present all available information so that it can serve
as a guide for the subsequent development of the project.
By and large, we can generate two main types of document:
" Reports��and��schedules: these are documents presenting the results of
a deep study. Their aim is to present the contents in a structured and
methodical fashion using accuracy, order and rigour so that they can be
used as a guide or handbook for the project.
" Presentations: these are documents that reveal the general lines of the
study. Their aim is to describe the main concepts of the study in an orderly,
synthetic and graphical way, so that they can be used as the summary of
the project.
Reports should only be presented after editing and formatting and they should
adopt a formal and precise language. Reports normally contain the following:
" Executive��summary: this is a brief summary that positions the systems
implementation project and its contents in terms of time, space, its aims
and its solutions.
GNUFDL " PID_00148382 65 Free software implementation, projects and companies
" Introduction: this describes the strategic position of the organisation
and the need to carry out a systems implementation project in specific
circumstances.
" Analysis��of��the��current��situation: this should include a summary of
the study, an analysis and the conclusions on the organisation's current
system in relation to its strategy.
" Definition,��aims��and��scope: this describes the systems implementation
project, the general concepts of the proposed solution, justification of the
use of free software and its suitability for the organisation's strategy.
" Architecture��of��the��system,��infrastructure��and��technology: this
describes the general and functional architecture of the system, the
infrastructure it requires, the technology and standards it uses, and the
end licences. Integration tests for the different elements may also be
included.
" Human��and��material��resources: here we describe the human and
material resources needed for the everyday operation of the system in the
organisation.
" Implementation��and��maintenance: this describes the implementation
methodology used, the features of migration, user training, adaptation of
the organisation and the necessary maintenance of the installation over
time (usually over a period of five years).
" Scheduling: this details the monitoring and relationship between the
stages of the project over time, taking into account the resources allocated
at any one time. It usually takes the form of a chart in which the stages
are plotted against the time axis.
" Financial��planning: this describes the assessment of the cost of
conducting the project, breaking down the cost of implementation
into various items (e.g. cost of project management, necessary human
resources, material expenses, software development and adaptation,
infrastructure installation, etc.).
" Synergies��with��the��free��software��community��and��other��projects��and
bodies: depending on the characteristics of the organisation, we can
include a section describing the relationship between the solutions used
and the free philosophy sector, the use of similar projects and relations
with other bodies or with the free software community.
GNUFDL " PID_00148382 66 Free software implementation, projects and companies
" Conclusions: we need to highlight the project features that meet the
strategic needs of the organisation and the benefits obtained from the use
of free software.
" Technical��appendices: these can come in useful for the subsequent
development of the project. For example, for the analysis of the system
requirements.
We obtain two documents from this phase:
" The report or project plan, which is presented as technical documentation
of the project.
" The presentation, which will be used at the executive meeting in the
subsequent phase.
2.5.3. Presentation of the proposal
In this phase, we present the proposal to the organisation, usually during an
executive meeting with its management body. The purpose is to inform the
organisation of the final results of the analytical stages so that the organisation
can evaluate the proposed solution and the monitoring of the project, and
consider its continuity.
This phase is usually implemented by presenting all of the aspects of the
project in the form of charts and summaries, using the presentation document
from the previous phase. In addition to the presentation, we must deliver the
project plan with the results of the design stages.
It is particularly important in this phase to focus on the communication and
transfer of information, highlighting the relationship between the proposal
and the strategic aims of the organisation. Though not the norm, we may be
asked to reformulate some aspects of the proposal, which will, in any case,
need to be fairly minor in quantitative and qualitative scope.
The committee in charge of validating the implementation of the system may
be reticent to the use of free software, so it may be wise to justify the proposal
by questioning certain preconceived ideas, explaining the advantages and
disadvantages of its use and even discussing the free philosophy in general and
licence models. The document drawn up in the design phase of the proposal
on issues related to the project and free software may prove useful here.
This phase is closely related to the subsequent phase, the final evaluation,
since decisions on whether or not to continue with the project are often made
at presentation meetings.
GNUFDL " PID_00148382 67 Free software implementation, projects and companies
2.5.4. Final evaluation
The final evaluation phase of the formalisation of the proposal is the fourth
control point of the project, designed to evaluate the work carried out in the
design stages of implementation and the proposed project solution. It must
also resolve the feasibility and continuity of the project for the development
and system implementation stages.
This phase is closely related to the previous one because the presentation of
the project plan and exchange of information between the organisation and
the team that came up with the design is essential if we are to take into account
all of the implications of the proposed solution. The proposal presentation
and validation phases may be merged for making decisions regarding the
continuity of the project.
The importance of this control point is twofold:
" Firstly, because the formalisation of a proposal closes the theoretical and
conceptual cycle of the analysis and design of the system and its associated
implementation project. The subsequent stages will be mainly practical.
" And secondly, because the organisation will finally determine whether or
not the project will be concluded and meet the aims of the strategic action,
implementing the series of changes considered in the proposal.
Hence, as explained in the previous sections, the organisation must evaluate
the aspects of the project it considers to suit its strategy; for example, the
characteristics of the solution to be implemented and the financial costs of
the project and implementation of the system.
It might also be a good time to analyse, evaluate and adapt certain specific
details of the implementation of the system in the organisation, considering
and defining certain aspects of change management, implementation
scheduling, pilot tests and user training.
The organisation's evaluation of the proposal can end with one of three main
types of decision:
" Feasible��project. The organisation accepts the proposed solution without
making any major changes to its specifications. Any adaptations relate to
the implementation schedule or the inclusion of certain financial items,
for example.
" Feasible��project��subject��to��conditions. The organisation considers certain
adaptations to the proposed solution to be necessary. These changes may
or may not be minor, but part of the proposal will have to be drawn up
again if the project is to be given the go-ahead. The changes may be related
GNUFDL " PID_00148382 68 Free software implementation, projects and companies
to the tools implemented or to the partial execution of the project, for
example.
" Project��unfeasible. The organisation considers the project unfeasible and
abandons the implementation of the system. Although this does not
usually occur at this stage in the project, a drastic change in organisation
strategy or the inability to secure financing to conclude the project are
possible reasons for abandoning implementation.
The result of this stage is twofold:
" Firstly, we obtain the project plan, which is agreed and validated by the
organisation.
" And secondly, the organisation makes a decision as to whether or not to
continue with the project implementation.
2.6. Development
This section will define the development stage of the implementation project
and describe its main characteristics and special features. It will detail the
various phases of the process, the main factors influencing its development
and the results that this stage should generate.
The development of the system is the stage in which the solutions
described in the project plan are implemented, together with all of
the requirements for its start-up. The purpose is primarily to adapt,
collect and produce all of the necessary elements in order to perform
implementation with the utmost guarantees of efficiency and efficacy,
and to minimise intervention time.
This stage uses documents from the previous stage, mainly the project
plan and analysis of the system requirements to be implemented. These
documents are essential for the preparation, structuring and organisation of
the development of all components needed to implement the project.
This stage has two specific aims:

section of the first unit.
In general, we can divide the development stage into three main phases: the
allocation of resources, the configuration or development of the software and
the final evaluation, although the individual existence of these stages will
depend largely on the project typology.
The allocation of resources and software development phases can be executed
at the same time, depending on the project type. It is also possible for these
two phases to overlap rather than being simultaneous, perhaps because of
differences in the delivery dates of the various resources.
We also need to remember that the development stage is closely related to
the subsequent stage: implementation or system migration. In this case, some
tasks may overlap or be carried out at the same time in order to cut short the
project schedule, though this could have financial consequences that need to
be taken into account, caused by aspects such as the need for more human
and material resources.
2.6.1. Allocation of resources
The aim of this first allocation of resources phase is to select and obtain all
of the necessary resources to implement the system in the organisation, in
order to obtain all of the elements directly required for the implementation
and operation of the new system.
(20)
One of the main aims of this first phase is to equip the organisation with the

integrates with the rest of the project.
GNUFDL " PID_00148382 70 Free software implementation, projects and companies
Evaluation of the diverse proposals is specific to the project, system and
organisation. Broadly speaking, we can assess the following:
" System��and��interoperability: we need to evaluate each element alone and
its adaptation and integration with the system, project and organisation.
" Functionality��and��ergonomics: we must assess the ease of handling
and configuration of each element and the knowledge required for its
fine-tuning and everyday use.
" Efficiency��and��performance: we need to assess functional and operating
performance in line with the needs of the system.
" Efficacy��and��reliability: we must evaluate the reliability and coverage of
the aims in relation to the system requirements.
" Implementation��and��migration: we should evaluate the ease of
introducing the element into the organisation and the tools it offers for
migration from the current solution.
" Maintenance,��support��and��guarantee: we must evaluate the operation
and maintenance needs of the element, and the support and guarantees
offered by providers.
" Economics: we need to evaluate the cost of the element in terms of its
promised results and the advantages and disadvantages of the impact on
the organisation's operation.
Implementation of the project may also require the allocation of human
resources to the organisation, for either direct or indirect system handling.
Since the project stems from a strategic action within the organisation, a
change in methods and procedures may require a restructuring of the staff
involved.
The biggest changes in this regard would take place in new organisations
or existing ones that do not use computer equipment in their day-to-day
operation. The demand for technological profiles goes hand in hand with
the level of technological implementation, the type of project and the
characteristics of the organisation.
In all events, the selection of human resources will have to be integrated
into the typical recruitment methodology of the organisation but we should
stress the need for the candidate profile to correspond to the technological
requirements of the organisation.
GNUFDL " PID_00148382 71 Free software implementation, projects and companies
2.6.2. Software configuration and/or development
The aim of the software development phase is to implement all adaptations
required by the free software solution in order to adapt it to the project plan.
This phase can also include the development of tools to help with data or file
conversion for systems migration.
The main aim of this phase is to ensure that the free software solution matches
the project requirements, with the adaptation and encoding of all necessary
changes, taking advantage of the open nature of the source code and the
freedom to develop it.
The length of this phase will depend directly on the changes that need to be
made to the proposal. Generally, we can distinguish between three different
cases:
" Direct��implementation. When the software is to be implemented
directly, the development scenario is limited to adaptation of the
configuration files or software parameters.
For example, the operating system configuration (language, network
access, etc.) or the parameters of office automation tools (templates,
language, etc.). This case requires minimal investments in time and
financial resources in comparison to the other two.
" Software��evolution. Software evolution encompasses the extension or
adaptation of the source code of one or more free software solutions to
adapt its operation to that of the organisation.
The importance of the results means that we must proceed with the usual
rigour of software engineering, establishing an adequate life cycle for each
modification; it could also include software re-engineering.
One example might be the introduction of additional calculations in
accounting management software or the modification of the downloading
manager of a web browser.
" New��development. New code is developed when no solutions can be

means that we must proceed using software engineering methodologies
adapted to the project. For example, the creation of industrial design or
architectural or electronic device control software.
Hence, any software development project will be guided by its specific life
cycle and will establish the relevant control and quality milestones, while
evaluating monitoring and results using the most appropriate methodology.
GNUFDL " PID_00148382 72 Free software implementation, projects and companies
Regardless of the development format, in this phase, it is useful to generate the
documentation for the software adaptation process with a list and description
of all details subject to modifications, using the same rigour as for new
developments. In these circumstances, we need to take into account the end
licence for the evolving solution, since the freedom of the source code is
usually inherited from the original solution.

2.6.3. Final evaluation
The final evaluation phase of the development stage is the fifth control
point of the project and its aim is to ensure that the development meets the
requirements of the project plan. It is also designed to reduce the overall risk
of the project by validating the viability and adaptation of development to
the organisation's strategy.
The evaluation of this stage usually depends on the typology of the

solutions to conclude the development. It can also be related to user training
and pilot tests because it can be useful to find out user opinions in order to
fine-tune certain aspects of the development21.
The importance of this control point is twofold:

" Firstly, because it revises, evaluates and assesses the qualitative
development of the solutions and their adaptation to the strategic
requirements of the organisation.
" And secondly, because it supposes the completion of the process of
creating and adapting the solution, and the start of the definitive
implementation and integration of the system in the organisation.
(22)
The development evaluation phase is generally a good time to introduce users

to the features of the system, and the situation can be regarded as the start of
the training and adaptation of users to the new environment. These actions
can take place as part of the management of the change that the organisation
needs to carry out in order to overcome any misgivings or fears among users22.
The final evaluation of the development stage can end in one of three main
types of decision:
" System��implementation��is��feasible. The evaluation determines that
the system meets the requirements of the organisation and that all
modifications of the original solution have been developed and integrated
correctly. Implementation of the system in the organisation may begin.
" System��implementation��is��partially��feasible. The evaluation determines
that the system partially meets the project requirements on the control
date. This situation is normally due to production delays, which can occur
as a result of unexpected events, such as the lack of material resources,
long delivery delays or the lack of human resources for production.
In all events, the feasibility of the project is not affected, but we will need
to take into account the fact that implementation will be delayed.
" System��implementation��is��unfeasible. Although it is rare for the
development of a solution to be unfeasible, there may be exceptional
factors affecting the decision that could not be solved during this stage.
This type of problem is normally associated with factors outside the scope
of the project, such as sudden changes in strategy or a lack of funds.
Abandoning the project at this stage will have serious financial, functional
and moral implications for the organisation and will make it difficult to
take any further action in the future.
The result of this stage is twofold:
" Firstly, we obtain the system to be implemented (tested and integrated),
which will meet the project requirements and the strategic needs of the
organisation.

" And secondly, we will have assessed the feasibility of implementation and
made any adjustments to scheduling as a result of the evaluation of pilot
tests.
2.7. Implementation and migration
This section details the technical aspects of migration to free software systems
and their implementation.
Most implementation projects are also migration projects because they
start off with a scenario in which there is a computer system based
on proprietary software already in production. Implementation from
scratch takes place in new organisations that look to free software
solutions to start up their first system or in organisations that currently
have no computer system, which is rarely the case.
Implementation from scratch is always much more straightforward than
migration in terms of the technical problems that the project will need to
solve, mainly because there will not be any compatibility problems with
existing systems. Nonetheless, we do need to bear in mind that the users of
the new system will usually be familiar with proprietary operating systems
and applications, so planning the training is just as important in migration
projects.
This section will refer exclusively to migration projects because they are
the most difficult and because projects implemented from scratch can be
considered a subset of migration projects with the particular feature that they
allow greater freedom to decide on the final scenario. This freedom comes with
the condition that more attention must be paid to non-functional aspects of
the system, such as correct dimensioning.
We will begin by describing the different types of migration project and the
most crucial aspects of the planning. We will then offer advice and guidance
for executing the migration and evaluating its results. And finally, we will
conduct a detailed study of all the services involved in the migration project
and the most popular free software solutions for each.
2.7.1. Types of migration
We can carry out a range of possible types of migration to free software systems
in organisations: aims-based, or depending on the elements of the system that
will be migrated; and scope-based, or according to the number of elements
that will be migrated.
GNUFDL " PID_00148382 75 Free software implementation, projects and companies
Aims-based:

operating systems from the BSD23 family or other free systems tend to
be more reliable and offer better performance, which will increase the
productivity of the organisation, both by systems administrators and end
users (lower server response time).
" Migration��of��users��and��clients: this affects the client machines of users
and the applications running on them. In this case, we will need to train
and accompany the end users, who are generally less receptive to the use
of new applications and will be most affected by the change, which could
cause a temporary loss of productivity.
" Migration��of��applications: this only affects some of the applications
running on client machines or servers, the operating system of which does
not necessarily have to be GNU/Linux or any other free operating system.
More often than not, the operating systems continue to be proprietary.
It is sometimes a preliminary step towards migration of the operating
system. These are fairly straightforward migrations, such as those to
OpenOffice.org or MySQL Community Server.
Scope-based:
" Complete��migration: this is the result of combining the migration both
of servers and client machines. This type of migration must be planned
in such a way as to ensure that clients are not left without access to the
services provided by the servers at any time. Hence, the first step is usually
the total or partial migration of servers, followed by the migration of client
machines.
" Partial��migration: this is the result of a combination of the partial
migration of the servers or part of the clients, which means that there
will still be machines based on proprietary software in the system.
One common scenario is that where a single system contains clients
based on free software and clients based on proprietary software, whose
configuration will depend on the needs or preferences of the end users.
" Migration��based��on��virtualisation: this can be viewed as a type of partial
migration where we migrate servers and client machines at the same time
as we continue to install and run proprietary software applications that
could not be included in the migration, whether because there are no free
GNUFDL " PID_00148382 76 Free software implementation, projects and companies
software equivalents or for other reasons. With virtualisation, we can start
up a proprietary operating system on a free operating system and use it as
normal with proprietary software applications.
We also need to remember that while the typical migration scenario is one
where we switch from a proprietary operating system to GNU/Linux, there are
other possible combinations, such as:
" From a proprietary operating system to a free operating system, such as
The OpenBSD operating

those of the BSD family.
" From a free operating system to another free operating system.

successfully to a free software system. There are as many ways to plan as
there are projects and they will all be valid to an extent if they meet the
requirements and features of our migration scenario. Nonetheless, depending
on our migration planning, we can extrapolate four main migration strategies:
" Single-step��migration: this involves carrying out the entire migration
process in a short space of time, in a single day or during public holidays if
possible. The strategy requires identifying and defining all of the tasks that
need to be performed, since a mistake in any of these could leave the entire
system inoperable, with the subsequent risk of delays and user rejection.
This is the most economical strategy and is usually used for small systems
with few clients and a single server, as is the case of small companies.
" Pilot��migration: the first step is to migrate a small part of the system,
which will be used for practising and evaluating the success of the
migration before we implement the rest of the system. The pilot system
usually consists of a number of servers and client machines, but it can
also be a single server and a single client machine. Although it is very
important to plan correctly, this strategy offers greater flexibility for
modifying the migration approach and correcting possible problems.
The drawback to the strategy is that it requires far more resources and
is therefore usually used in organisations with medium-sized or large
systems.
" Group��migration: this involves defining user groups based on their
functional characteristics and carrying out migration progressively with
each of these groups. One of the main advantages of this strategy is that
it enables us to minimise risks and learn from each migration. Moreover,
since migration only affects part of the system, we can reduce productivity
losses. The disadvantage is that we often need to keep the previous systems
GNUFDL " PID_00148382 77 Free software implementation, projects and companies
running while we set up the free software system. It is usually a good time
to renew hardware when carrying out group migration, and vice versa.
" User��migration: this is similar to group migration, the difference being
that only one user is migrated each time. As a result, the strategy
requires very few resources but is unfeasible in large and medium-sized
organisations, where migration would take too long due to the high
number of users. It could, however, prove useful for the migration of
critical systems and users that require special monitoring.
These strategies are not mutually exclusive and several of them can be used
in any one project. For example, in an organisation that has some smaller
or less important departments, single-step migration can be carried out in
these, while pilot migration can be carried out in others before moving on
to complete implementation. Similarly, group migration can be seen as a
combination of single-step and pilot migration.
2.7.3. Hardware and software inventories
In order to plan migration, we need to identify the hardware and software
available in the initial situation that we wish to maintain after migration. As a
result, we must carry out a detailed inventory of both hardware and software.
The hardware inventory should include all machines available for migration
including those that have been withdrawn, since we may be able to use some
of these again.
Hardware can be grouped into the following categories:
" Hardware��with��full��GNU/Linux��support: this includes hardware with
out-of-the-box support in the Linux kernel or free drivers, and hardware
for which we need to use proprietary drivers, either directly or using
adaptors. Most hardware has good support on GNU/Linux, so it will fall
into this category. We will describe each of these situations in detail later
on.
(24)
" Hardware��with��limited��GNU/Linux��support: this includes hardware

the more recent distributions of GNU/Linux, hardware that runs with
very old drivers whose maintenance has expired, and hardware with free
drivers that have functional limitations in comparison to the proprietary
drivers24.
GNU/Linux distribution
The production of a GNU/Linux distribution involves checking that all the packages
included in the distribution are compatible with one another and, most importantly,
GNUFDL " PID_00148382 78 Free software implementation, projects and companies
with the kernel version. Thus, there will always be a gap of some months between the
date of the appearance of the distribution and that of its kernel, which is older.
(25)
" Hardware��with��no��GNU/Linux��support: this includes hardware that

virtualisation solution could still be

without GNU/Linux support but when this is the case, it is either because
the hardware is very new and the relevant drivers have not yet been
developed, or because the hardware is very old and incompatible with
the newer versions of the Linux kernel or because the hardware is
dependent on a specific operating system and cannot therefore be used
with GNU/Linux25.
We can also classify hardware with GNU/Linux support by the type of support,
as follows:

the use of Windows drivers.
" Hardware��with��proprietary��driver��support: the free software community
does not maintain drivers for this type of device so we will need to use
proprietary drivers, often supplied by the manufacturer. This is usually
the case of hardware with very specific functionalities, such as graphics
accelerators. Nonetheless, support for this type of device is gradually
increasing and the manufacturers themselves often open up their drivers.
" Hardware�� with�� adaptor�� support: this hardware is supported by
proprietary operating systems but not by GNU/Linux. Fortunately, tools
called adaptors are available so that we can use the drivers of these
proprietary operating systems in GNU/Linux.
Once we have classified the hardware correctly, we will obtain a clear idea
of the available resources and the need to purchase any new equipment.
Moreover, as we mentioned earlier, the hardware requirements of GNU/Linux
systems are considerably lower than those of proprietary operating systems,
so obsolete machines can be reused for services such as printing or e-mail.
GNUFDL " PID_00148382 79 Free software implementation, projects and companies
Once we have completed the hardware inventory, we will need to do the same
with the software. We will have to identify all of the proprietary software
applications used in the system before migration and the best free software
applications for replacing them.

The benefits are clear: the potential contribution of external developers and
users and increased visibility for the organisation.
2.7.4. Network and structure diagrams
This section describes two essential elements of systems migration: the
network diagram, which illustrates the connectivity between the diverse
elements of the system, and the structural diagram, which indicates its
physical location.
Thus, once we know which hardware and software will be affected by

" Printers. Indicate the name of the printer and the print server or client

" Other��network��equipment. Indicate the main equipment forming the

example, hubs, routers, switches and wireless access points.
GNUFDL " PID_00148382 80 Free software implementation, projects and companies
" Connectivity��between��elements. Indicate the wired and wireless network
connections between the various elements of the system. Indicate the
organisation's local network connection to external networks such as the
Internet, virtual private networks (VPN) and virtual organisations (VO).
It is very important for each machine to be uniquely identified in the network
diagram.
First of all, we need to draw up a network diagram illustrating the status of the
system before migration. This diagram will be used to study the possibilities
for optimising the current network, such as alleviating server bottlenecks or
connecting certain local printers to a central print server. We will also decide
which new equipment and network elements will be introduced in the system
as new servers, which old equipment can work with GNU/Linux or discuss
the implementation of a wireless network.
With these elements we can create a network diagram for the system after
migration. This diagram will be essential for defining the planning and
strategy of the migration and will serve as a guide during implementation.
Thus, it is a good idea to keep the network diagram up to date, ensuring that
it offers a true picture of the system status.
As explained at the beginning of the section, the structural diagram reflects the
physical location of the equipment inside the organisation; in other words, it
tells us what equipment there is in each room.
As we did with the network diagram, we will create a structural diagram to
illustrate the status of the system before migration, which can then be used
to decide on the location of the equipment after migration.
One of the most common consequences of migration is the introduction of
servers for a small number of services, sometimes even exclusively. As a result,
the servers are usually grouped together in the same physical location (usually
a server room) that meets the specific requirements for climate control, power
supply and accessibility, among others. Another example is the connection
of printers (thus far local) to a print server, which can be located in the same
room.
Although structural diagrams are not very important in small organisations
with just ten or so machines, in bigger migration scenarios, it is essential to
know the location of each piece of equipment and network component.
GNUFDL " PID_00148382 81 Free software implementation, projects and companies
2.7.5. Execution of migration
When carrying out any migration, regardless of the strategy adopted,
there is a series of technical tasks that almost always crop up again and
again: equipment installation, data migration, production of backup
files, emulation of applications, etc. Besides these technical tasks, it is
important to have a management plan in place to deal with any risks
that may appear during migration.
This section will look briefly at each of these tasks and offer guidelines for
their completion:
" Equipment��installation. Automatic equipment installation tools are
available for easy installation and configuration of more than one in a

One such tool is SystemImager, which automates the installation of clones

of directory services.
" Making��backups.
Backup is the term generally used to refer to the copying of data to allow
a system to be restored after loss of information. The implementation of
GNU/Linux systems often involves the formatting and partitioning of the
equipment involved in the migration, so we need to make backups of the
existing data in order to restore it later on the new system.
GNUFDL " PID_00148382 82 Free software implementation, projects and companies
If the organisation has an up-to-date backup mechanism, one option is to
use this to recover all the information that needs to be copied to the new
equipment.
If the organisation has no backup mechanism, we can set up a storage service
exclusively for the storage of the data that needs to be migrated. Another
option is to implement the storage service envisaged in the project plan first
and then provide access to the system users so that they can store their data
before the user equipment is migrated. In both cases, the participation of users
is fundamental.

).
" Emulation��of��applications��and��virtualisation.
Performance of the software inventory will serve to determine which
applications cannot run natively on GNU/Linux and cannot be replaced
by an equivalent free application. If these applications are essential and we
need to continue using them, we have two possible solutions: emulation or
virtualisation.
Wine, the most popular free solution
Wine is the most popular free solution for running native Windows applications on a
GNU/Linux system. Although Wine ( http://www.winehq.org/ ) is usually referred to as
an emulator, it is more correct to say that Wine provides a layer of compatibility for
Windows applications. Wine is in fact an acronym of Wine Is Not an Emulator.
Wine does not need to install a Windows partition but it can be useful to have some
native Windows libraries in some cases. Applications that run with Wine can access
the file system, network and printing services in a completely transparent way. The
Wine website contains information on the supported applications and their level of
functionality.
For applications that do not run correctly with Wine, it is possible to run them on a
virtualised operating system. As explained earlier, virtualisation allows us to run one
operating system over another. In this case, we would run the application on a virtual
Windows system on a GNU/Linux system. The most popular free virtualisation solutions
are QEMU, Xen and KVM. In all events, virtualisation should always be considered as a
last resort because we will have to carry on using and paying for proprietary licences and
because it is a big consumer of system resources.

management" for more
details on how to draft a risk
management plan.
GNUFDL " PID_00148382 83 Free software implementation, projects and companies
The risks and their relative importance will depend on the migration scenario
and the features of the organisation. For example, some organisations may
consider it a priority to guarantee the security and integrity of certain
confidential data, so this contingency will need to be provided for and a plan
drawn up to solve it in the event that it does occur.
As a general rule, we suggest that you keep the migration process reversible
until you have fully verified the new system, i.e. that you will be able to
return to the starting point in the unlikely event that migration fails or proves
unfeasible.
2.7.6. Evaluation of the migration
In any migration project, it is essential to evaluate both the end system
and the migration process. This evaluation can be done once we have
completed the migration, but it can also be carried out during the
process, if it is not conceived as a single-step process.
Hence, the project plan must include a series of clear indicators. These
indicators may include some of the following, which refer to the operating
system, servers, applications and users:
" System��indicators. Have the reliability, performance and security of
the system increased since migration? How has the real (as opposed to
estimated) cost of system maintenance changed? Have new services been
introduced into the system? How do the administrators see the new
system? Has the number of problems with system services fallen since
migration?
" Operating��system��indicators. How many machines have been migrated
to the new system? Does all of the equipment work properly? Is all of the
hardware supported by the new system? How often have virtualisation
solutions been required?
" Application��indicators. For how many existing applications has an
equivalent application in free software been found and implemented?
What functionalities have been gained and lost with regard to the
original applications? How many applications run through emulation or
virtualisation? How many applications was it necessary to modify? How
many applications have had to be developed from scratch?
" User��indicators. How many users have been migrated to the new system?
What is their opinion of the functional and non-functional aspects of the
new system and the new applications? How has their productivity varied
GNUFDL " PID_00148382 84 Free software implementation, projects and companies
in the short and long term? Has the number of user problems fallen since
the new operating system was installed?
2.7.7. Migration of the services of a system
Most organisations have a series of basic services that must be paid
special attention when planning and executing migration:
" File system
" Printing service
" Directory and authentication services
" Network service
" System management and administration
" Web servers
" Databases
" Desktop environments and office automation applications
" Corporate applications

on existing ones.
Nonetheless, migration is an excellent opportunity for analysing and revising
the current status of the system and designing an architecture that meets
both the current and long-term needs of the organisation. Hence, we need to
consider the inclusion of new services not present in the original system.
File system
We can be faced with two situations when migrating the file system,
depending on whether all or only a number of the clients are being migrated:

In this case, the most popular solution is Samba, a free protocol

computing scenarios.
The choice of one or the other (or the choice of another system) will depend on
the migration requirements. It is possible to use NFS or OpenAFS in networks
that include Windows and GNU/Linux clients.
For the migration of servers operating with GNU/Linux, there are several file
systems but the most widely known are Ext3 and XFS. Their functionalities
include journaling, assignment of quotas and access privileges based on ACL
(Access Control List) by file and directory.
When migrating file systems, we need to pay attention to the mapping of the
Windows ACLs to Posix ACLs, since we can lose granularity here. In practice,
this does not usually occur because organisations usually do not make full use
of the granularity permitted by Windows ACLs.
Printing service
Printing is one of the most common sources of problems in organisations,
generally because printers are installed with no planning, which leads to
numerous several technical issues and, very often, a waste of resources
(paper, ink, electricity). Migration to a free software system is actually a good
opportunity to optimise the printing service.
Of the available free software solutions, CUPS is the print server used by
most GNU/Linux distributions and is in fact the best option for almost all
migration scenarios. One of its main advantages is that it provides us with
a print service both for GNU/Linux clients and Windows clients, because it
implements Internet Printing Protocol or (IPP).
IPP is a printing standard for both LAN and WAN networks that supports
communication between clients and servers, between different servers and
between the selected server and printer. It is supported by all modern printers.
Before carrying out migration, we need to check the support and drivers for
each printer.
GNUFDL " PID_00148382 86 Free software implementation, projects and companies
Directory and authentication services
The purpose of a directory service is to ensure that certain information is

user accounts together with their privileges so that all the system applications
and services can access it to obtain this type of information, which should be
complete given its nature.
Thus, a directory service needs to offer the following functionalities:
" The available information must be modified and organised into a
hierarchical structure.
" Use of a standard data schema to ensure compatibility and interoperability
with as many applications as possible.
" User authentication and guaranteed interoperability with other
authentication services.
" Administration of access rights to the information in the directory service.
" Secure transfer of information between clients and the directory service.
For authentication with a directory service, the most common free software
solution is a combination of OpenLDAP and Samba, where the latter serves as
a database of user accounts and OpenLDAP acts as a directory service. There
are many applications compatible with LDAP, including the office automation
package OpenOffice.org.

information stored in the directory service and there are also web-based
graphical interfaces available for the administration of users and groups.
A directory and authentication service based on OpenLDAP and Samba will
also allow the simultaneous use of Windows and Linux clients. In fact,
OpenLDAP also acts as part of the authentication service and as an integration
tool in mixed scenarios with GNU/Linux and Windows clients. If we are
carrying out a complete migration to GNU/Linux, authentication is also
possible with Kerberos. Kerberos is an authentication protocol that allows two
computers to reveal their identities to one another securely.

both in their definition and in their implementations.
One aspect to consider when migrating network services is the use of
open standards, even when they are not needed (as in the case of small
local networks) as this does away with the need for specific modifications
from hardware manufacturers, which can eventually cause compatibility
problems with other systems when new services are implemented and even a
dependency on the manufacturer.
The network services include the following:

System management and administration
Most system control and management applications are not native to
the operating system and manufacturers often supply versions of these
applications for different operating systems. The downside to this is that while
there are many systems management applications for GNU/Linux, they are
not based on free software.
In all events, the management and control of free software systems is very
different to that of systems based on proprietary software, such as Windows.
Administrators of free software systems normally use a series of management
tools rather than just one, each specialising in a part of the system. Thus,
administrators have much more freedom to make adjustments and correct
problems with their systems, which is one of the reasons for the well-known
reliability and security associated with free software.
An initial option for the automation of administration tasks in GNU/Linux is
the use of cron and at. The former ( cron ) is an administrator of background
processes that runs programmes at regular intervals. The at command also
allows programmes to be run at specific times.
All GNU/Linux systems offer the basic functionality of administration from a
remote terminal ssh on another client or server in exactly the same way as if
it were a local machine, even through the graphical interface of the desktop.
The combined use of ssh, cron and at covers many of the maintenance tasks
of the administrator.
Other system utilities such as strace, lsof and netstat offer diverse
functionalities for detecting and analysing errors, and can be useful in server
management.
Network��management
The solutions available for the management of TCP/IP networks as free
software include Nagios and OpenNMS.
Nagios allows us to monitor servers and services in order to detect network
problems in systems based on GNU/Linux. A background process controls
the specified services and servers and sends the information to the Nagios
server, which informs the system administrator if it detects a problem. By
means of a series of plugins, Nagios can actively and passively monitor typical
network services such as web and mail servers, besides others such as database
management systems.
GNUFDL " PID_00148382 89 Free software implementation, projects and companies
OpenNMS is a network management application that uses the FCAPS model
and allows us to determine the availability of the different services, store the
information and generate reports, and inform of events.
However, the management of more complex systems and networks may
require the use of tools that are not available as free software.
Software��management
Software management involves client installation and restoring, standard
and specific applications distributions and the management of updates and
patches for the entire system.
The solutions available as free software include m23, a software package for
systems based on the Debian distribution that allows initial client installation,
including the definition of partitions and the detection of hardware, the
distribution and updating of software and the restoring of clients.

as PHP or Perl). The modifications needed to ensure compatibility of these
projects in Apache are minimal or non-existent.
Projects developed in proprietary technologies such as ASP are a special case,
since considerable effort is required for them to work on Apache. Wherever
possible, it is preferable to implement the web project again in alternative
technologies such as PHP to ensure technological independence in the future.
This obviously involves more work but the opportunity can be used to
optimise the web applications and contents of the organisation.
GNUFDL " PID_00148382 90 Free software implementation, projects and companies
It is now increasingly common to see PHP used as a web programming
language and LAMP platforms (Linux, Apache, MySQL and PHP) have become
popular over recent years for offering web contents and applications.
Databases
There are many free software alternatives for the implementation of database
management systems, but the most common are MySQL, PostgreSQL, Firebird
and MaxDB. Choosing one solution over another will depend on the
requirements of migration.
In all events, free databases are mature products that have been tried and
tested in production environments and can in fact be regarded as one of
the leading areas for free software and the GNU/Linux system in business
environments. These solutions also have versions for proprietary operating
systems so they could be used when migrating applications only.

system, we could migrate the operating system to GNU/Linux.
Most databases have fairly standard administration and query mechanisms,
which theoretically encourages interoperability and the use of other solutions
along with easy migration of data from one management system to another.
This means that applications can continue to access the data transparently
and without the need for further modifications.
Thus, database migration involves two operations:
" Migration��of��data��to��the��new��database. The effort required for this
operation will depend on the initial status of the data. If the data can
be accessed by SQL queries, an export or data transfer operation with
subsequent importing to the new database should suffice. If the data
are stored in a proprietary format or even as text files, we will need to
implement a parser and subsequently import them to the new database.
" Verification��of��data��access��from��applications. If the applications use a
standard data reading mechanism (such as SQL queries), access will have
to be set up in the same way, unless we are using commands that do
not satisfy the standard. If the applications use standard drivers such as
ODBC or JDBC, or a proprietary interface, it will be necessary to replace
the original database driver with that of the new database or to implement
a new interface. In both cases, this step could require considerable effort
and cause problems with interoperability.
GNUFDL " PID_00148382 91 Free software implementation, projects and companies
As a general rule, for easier database migration, we need to avoid as far as
possible the use of predefined query procedures and specific manufacturer
extensions for accessing the data from the applications. Instead, it is advisable
to use standard drivers like ODBC and JDBC, which are easily interchangeable,
and to implement SQL queries in the most modular way possible and separate
from the rest of the programme.
Desktop environments and office automation applications
There are two main desktop environment options in GNU/Linux systems:
GNOME and KDE.
Both GNOME and KDE provide an intuitive desktop environment with a
user-friendly windows manager suitable for all users and a development
platform for building applications integrated into the rest of the desktop and
between one another.
The choice of one or the other is largely a matter of personal preference. KDE is
generally more similar to the Windows interface and has more customisation
possibilities, but this could introduce further difficulties for new users.
Although there are many office automation applications for GNU/Linux
systems that offer good integration with the Gnome and KDE desktop systems,
there are two solutions that stand out above the rest: OpenOffice.org and
StarOffice.
OpenOffice.org is an open source, free software, office automation package
that is freely distributed. It is available for many free and proprietary
platforms, so it is often cited as an example of application migration. In
most cases, it is compatible with Microsoft Office and supports the ISO
OpenDocument data exchange standard, which can be used freely.

automation applications. With this format, we can easily separate the contents
of the file from its data, styles, version control and the pictures included in the
document. In addition, OpenOffice.org allows us to work with other formats
also based on XML.
Migration��of��files��in��Microsoft��Office��format
OpenOffice.org has mechanisms to convert and import files in proprietary
formats, such as those used by the Microsoft Office suite. It also allows us to
save files created with OpenOffice.org in proprietary formats.
However, this compatibility is not perfect and while the quality is usually
acceptable in most cases, there are sometimes differences in the format of the
documents, particularly those containing complex elements, such as macros
or other special features. In this case, it may be necessary to re-edit some of
the documents if we require the format to be identical to the original.
Hence, before converting and migrating the documents, we need to study
their features and classify them according to their use and technical
complexity:
" Editable documents: these need to be converted to a new interoperable
format such as ODT, so that they can be edited in the future.
" Read-only documents: these can be converted to PDF format, which
simplifies the migration process considerably.
" Basic documents: these do not contain macros, proprietary graphics,
formats or complex elements or styles such as footnotes, tables and
indices. They can be easily migrated by batch processing.
" Complex documents: these contain macros, proprietary graphics and
vector graphics, OLE objects, active objects, cross references, etc. They can
be migrated but will most likely require individually processing.
OpenOffice.org offers the possibility of converting several documents by
batch processing. All of the documents must be located in a source directory
and we will need to specify a target directory to which all of the converted
documents will be saved. In all events, we recommend checking the
conversion with a representative sample taken from all the documents.
In addition, we have two possibilities when it comes to dealing with complex
documents:
GNUFDL " PID_00148382 93 Free software implementation, projects and companies
" Convert the documents one by one so that we can correct any differences
with the original document before saving it in the new format.
" Revise the documents one by one to eliminate elements that could affect
the conversion process and then batch process them all.
Corporate applications
The term corporate applications is used to refer to applications
developed to meet the specific needs of the company or organisation
in which migration is being performed.
For migration purposes, we can distinguish between the following types of
corporate application:
" Applications that can be run problem-free on a free operating system,
such as multi-platform applications (those written in Java, for example)
or web-based applications (in PHP for instance, as we saw in the section
on web servers).
" Applications requiring slight modifications to be able to run on a free
operating system, such as those for correct database access for instance, as
we saw in the section on this topic, or for configuring new environment
variables.
" Applications that can run by emulation or virtualisation.
" Applications that cannot run on a free operating system, such as
applications implemented in languages exclusively for the proprietary
operating system.
Most corporate applications are proprietary so the company will not have
access to the source code. If it is not possible to run the application by
emulation or virtualisation, the best option is to implement the application
again as free software based, if possible, on an existing free software project.
2.8. User training, communication and support
Thus far, we have looked mainly at the technical aspects of the
implementation of free software systems. The importance of the technology
should not detract from the fact that one of the factors in the success of
any implementation project, particularly migration, is acceptance of the new
system by its users.
GNUFDL " PID_00148382 94 Free software implementation, projects and companies
This section will first describe the key elements of the free software training
plan of an organisation and some good practices to introduce and encourage
user acceptance. To conclude, we will take a look at the main channels of
communication and key elements of a user support system.
2.8.1. Training
Correct user training plays a very important role in the success of the
project. As a result, we should include it in our project plans from the
very start.
To plan the training, we need to identify first of all which user groups will
use which specific types of application. This will enable us to study the
differences between the proprietary and free applications, and hence evaluate
the difficulty in the adoption of the new applications for users. These elements
will allow us to plan user training to meet their real and individual needs.
Some free applications, such as browsers, e-mail clients and office automation
applications, are very similar to their proprietary equivalents. Obviously, less
training will be needed in these cases.
Materials
There are many materials on the Internet that can be used to train users or to
help us prepare our own materials.
Manuals and documentation are often only available in English, which can
be a problem for some users, and the interfaces of certain applications are not
translated or the translation is incomplete. In this case, we could think about
publishing our own documentation to overcome language barriers.
The European SELF project has a platform for creating and sharing educational
materials relating to free software and open standards.
Training��manager
The training may be held in the organisation, in collaboration with an outside
company or using an online learning platform.
In any case, it is important to facilitate access to training and materials
as much as possible. Attendance of training activities may or may not be
compulsory as this will depend on the organisation's policy.
GNUFDL " PID_00148382 95 Free software implementation, projects and companies
Online learning platforms have the advantage that users can adapt their
learning process and training access to their needs. Moodle is a free course
management system used to create what are known as online��learning
communities in which students can follow the training and communicate
with one another.
Another good option is to combine on-site training with an online learning
system.
Finally, we should not rule out the possibility of offering users some sort of
incentive to encourage them to attend the training, for example, awarding
certificates of attendance and achievement.
Types��of��user
Not all users are alike. Firstly, there will always be some users who are more
receptive to the new software than others. In most cases, however, once users
overcome their initial misgivings about the use of free software, they find it
very similar to proprietary software and are satisfied with its use, so we should
not worry too much if their first experiences are negative.
Secondly, remember that technical and non-technical staff will need a
different type of training and monitoring.
Technical staff will need more intensive training than normal users,
particularly if they have no previous experience of free software and are
used to working with a proprietary system that, in contrast, they are very
knowledgeable of. The participation of technical staff is also key to ensuring
the smooth running of the system after implementation. It is good practice to
motivate them and get them involved in the implementation process so that
they can get to know the system while it is being implemented.
2.8.2. Introduction to free software
In addition to training, another of the practices that can lead to a successful
free software migration project is the gradual introduction of the new
applications and services. This gives users time to get used to the new
environment and means that they are not confronted by a completely
unfamiliar system.
Installation��of��bridge��applications
GNUFDL " PID_00148382 96 Free software implementation, projects and companies
Many popular desktop applications are now available on GNU/Linux as well
as proprietary systems, such as the OpenOffice.org office automation package,
the Firefox browser or the Thunderbird e-mail client. Many server applications
and services can also be run on both systems, such as the MySQL database
manager or the Apache web server.
(33)
These types of application are called bridge applications and can be very useful
This would be a simple
applications migration, like the

estimating their training needs much more accurately.
Staggered��migration��of��services
The primary aim of any migration is to produce a smooth transition from
one system to another without the users noticing any major differences or,
if possible, without them noticing any differences at all. One strategy for
achieving this aim is to start migration on the servers, so that users can
continue working as normal until the system is prepared for the migration
of clients.
Services that can easily be migrated at the start include network services (DNS,
DHCP, etc.), web servers and database servers. It may be necessary to use
technological solutions that work well on heterogeneous systems, such as
OpenLDAP in combination with Samba.
This gives us enough time to train technical staff too, whose support can be
very useful for migrating clients and providing support to other users.
Both the introduction of bridge applications and the staggered migration of
services should be taken into account in the project planning.
2.8.3. Project communication
As we have seen, the implementation of a free software system and migration
to this system is a process that involves all of the organisation's users, not only
the technical staff responsible for its complete introduction and maintenance.
The mechanisms must be put in place for effective communication between
users and the technical and administrative managers of the organisation,
and we must ensure transparency throughout the process. As of result, the
communication activities must be set down in the project plan, which must
include:
" Initial��group��communication��to��all��users. We should use informative
meetings, notes, internal e-mails and advertisements on the organisation's
intranet to explain the reasons for the project and detail its general
planning before it is implemented.
GNUFDL " PID_00148382 97 Free software implementation, projects and companies
" Regular��communication��of��the��project's��progress. We should explain
which parts of the system will be migrated and when, along with any
changes made to the project. Meetings with a small number of users
should be organised at each phase of migration.
" Regular��meetings��after��conclusion��of��the��project. We should evaluate
the success of the project and conduct general monitoring of its results
and the experiences of system users.
2.8.4. User support system
A key element of the new system is the introduction of an issue management
system for users, allowing them to find the answers to their questions and
solve the technical problems caused by the situation. It is important to give
a fast and efficient response to all these problems, particularly just after
implementation.
When designing a user support system, we need to answer the following
questions as they will define the main features of the system:
" Who are the users?
" How does the organisation operate?
" What type of support do the users need?
" What type of support is offered to each type of user?
" How much support will be offered?
" How will the support be offered?
Pilot tests can be used as a basis for characterising most of the problems
encountered by users and for preparing a procedure for solving each one.
Similarly, we will need to identify the critical services and users of the system,
as these will be given preferential support.
We also need to bear in mind that more support means higher costs. It is
possible to provide more support in the weeks immediately after migration,
when the number of queries and issues is higher. In all events, the key to an
efficient user support system is fluid communication with users, to make them
aware that their problem is being looked into.
Lastly, it may be the case that a user support system was in place before

and diffusion of software have been developed. We can generally distinguish
between two basic and antagonistic trends:
" On the one hand, the proprietary philosophy, which defends the
protection of software by closing and privatising the source code,
combined with the use of licences with heavy usage restrictions.
" And on the other, the free philosophy, which defends the freedom of the
software and source code with licences guaranteeing user rights to run the
programme, study and adapt the source code and redistribute and publish
any improvements made to it.
These two philosophies have generated business models with conflicting
ideologies, operation, development and economics:
" The privative software model normally establishes a financial value that
has to be met by restricting the use of a binary format copy, which makes
it impossible for people or organisations without copyright or the explicit
authorisation of the copyright owners to adapt, correct or improve the
source code. Many proprietary licences prohibit the transfer of user rights
to third parties without the prior agreement of the copyright owners.
" The free software model tends to focus on the development and
adaptation of free and qualitative solutions to meet the needs of users and
organisations, and on complementary services for their implementation
and day-to-day operation. Hence, the business model based on free
software allows actions that are prohibited or restricted in the privative
software model.
The unique philosophical understanding of free software does not only
have a direct impact on the business model and business strategy, but also
on the definition, management, organisation and operation of technology
companies. Aspects such as the maturity of free software, the presence of a

world community of free software project collaborators and the viability of
its business models seriously question the traditional concept of a business
project.
The first section of this unit defines the different business models based on
free software, which are valid and viable to be put into practice as a business
strategy.
The second section focuses entirely on the drafting of the business project
and details the main aspects of the creation, organisation, production and
operation of a free software company.
The third section introduces free software production and describes the main
features of the creation, organisation, communication and development of
the source code.
Lastly, this unit has two appendices that briefly and systematically describe
the main free licences and open standards directly related to the free software
business.
3.1. Business models
This first section introduces the main free software business models, together
with the characteristics and features setting them apart from business lines
based on proprietary software.
By and large, the biggest difference between free and privative software
from a business perspective is the licence. Broadly speaking, a licence
is a contractual model by which the author of the product (or whoever
owns the copyright) establishes the rights and duties of the users of the
product and the scenario in which it can be used.
(34)
There is a debate between

on the sales of licences for restricted use of the binary format35, although free
software does not necessarily have to be obtained without payment. However,
much of the free software currently available can be obtained by direct, free
download from the Internet site of the organisation that manages it.
Direct or free downloads
Examples of direct or free downloads include:
" Debian GNU/Linux from http://www.debian.org/distrib/
" FreeBSD from http://www.freebsd.org/where.html
" KOffice from http://www.koffice.org/download/
" OpenOffice.org from http://download.openoffice.org/
The philosophical opening up of free software encourages business models
based on human capital, knowledge, customisation and the adaptation of
products, not to mention the constant evolution of the software. Hence, we
need to highlight the role played by the community of free software users,
which helps monitor the quality and evolution of free applications with a
level of performance that would be difficult to match in proprietary models.
Over time, the free software model has managed to consolidate an offer that

of free software projects
in the key areas where the
technology is used.
To an extent, the free software business strategy bases itself on
the aspects that set it apart from the proprietary model, such
as increased functionalities, tailored adaptation, numerous and
continuous revisions, guaranteed product security and quality of
operation, and a whole range of complementary services for its
implementation and day-to-day operation.
The following sections introduce the main business models deriving from the
conceptual philosophy of free software: development, consulting, installation
and integration, migration, maintenance, and support and training.
The business models described should be seen as complementing one another
rather than being independent. In other words, a combination of one or more
business models may be necessary to cover the business strategy.
GNUFDL " PID_00148382 101 Free software implementation, projects and companies
3.1.1. Development
The software development business model involves the total or partial
production of a product based on free software in order to be marketed
either directly or as part of a third-party implementation project, such
as those described in the second unit of this subject.
The definition of free software makes no reference to the strategy of selling
a free product at a price per copy sold but the characteristics of free
licences make this a secondary option, albeit one used intensively by some
organisations.
Packaged free products
Some organisations decide to offer their free products in packages (boxes, discs, manuals,
documentation, etc.) in exchange for the payment of an amount that, while lower than
the price of alternative solutions, is still greater than cost price. For example, the Ubuntu
distribution can be purchased at http://www.ubuntu.com/getubuntu/purchase.
Free software production is mainly a response to the sale of complementary
services with added value for clients, which also serve to extend the continuity
of the software, such as customisation or adaptation to a specific environment.

prove not to be viable if the free product forks into a branch supported by
the free community, causing the competitive edge to fade.
" Source��of��a��free��product. This is similar to the first model (better
knowledge) but with the difference that the company produces almost
all of the code. The client evaluates the positioning and competitive
advantage over the competition. This model receives the support of the
free community.
" Source��of��a��product��with��limitations. This is based on the previous
model (source of a free product) but with an implementation aimed at
GNUFDL " PID_00148382 102 Free software implementation, projects and companies
reducing competition, such as beginning distribution with a privative
licence and opening it up afterwards or limiting the initial distribution to
company clients.
" Special��licences. This involves the production of a single product
distributed under different licences (free and proprietary). The proprietary
product offers special implementations of the product, such as integration
with other proprietary products.
" Sale��of��a��brand. This involves the distribution of free products with
the image of a corporate brand, offering quality and added value from
the point of view of clients. These products are usually accompanied by
numerous complementary services for clients.
The choice of the type of software development business must go hand in
hand with the business strategy and be suited to the target market. Hence, an
organisation may decide to use a customised typology for each of the products
it plans to introduce on the market, based on the strategy and specific target
market of each product.
The free software development business model also requires a careful selection
of the licences of the source code it uses:
" The licence for the source code it modifies if the end product improves
an existing application.
" The licence for the source code it links to if the end product needs to
implement function calls to external libraries in order to operate.
" The licence for the source code it creates, i.e. when the source code is
completely new.
" The licence for the source code of the end product, which encompasses
the combined source codes of the end product.
The importance of carefully determining the licences associated with each part
of the source code used lies in the differences between the various free licences.
In other words, although all free licences guarantee the basic four freedoms,
they differ in their policies for licensing the redistribution of modified code,
which is precisely the object of the free software development business model.
Appendix I of this unit briefly describes the most important characteristics of
the main free software licences and explains the redistribution policy and the
compatibilities of linking and derived work.
GNUFDL " PID_00148382 103 Free software implementation, projects and companies
The selection and correct combination of licences will have a direct effect on
free software production and may have legal implications if it is not done
properly. The last section of this unit on free software production looks in
detail at how to select the relevant licence based on the product parameters.
Lastly, we should be aware that free software promotes and uses public
specifications called open standards to promote the universality and
interoperability of the formats handled. Appendix II of this unit includes a
brief description of the main characteristics of open standards together with
some examples.
3.1.2. Consulting
The consulting business model is based on the generation of
professional services to complement free software for users and
organisations.
To a certain extent, this business model is based on providing quality external

Consultancies can offer a broad range of professional services, which will
depend on the strategy and context of the business. Nonetheless, they will be
closely related to the study, analysis, design and evaluation of the free software
systems implementation project described in the second unit of this module.
There now follows a brief classification of the main services that consultancies
can offer their clients:
" Project�� management: this involves the creation and functional

security, performance, efficiency or efficacy, among others, and may be
performed before and/or after implementation of the system.
" Advice: this service is geared towards offering support and professional
help and advice for technological decision-making in the organisation.
These tasks can be carried out prior to the start of any implementation
project or during the study, analysis and design phases. In all events,
they form part of the professional support provided for strategic
decision-making on technological aspects affecting the future of the
organisation.
This list is by no means exhaustive or exclusive because the business model
can provide two or more services to cover its business strategy. In addition,
the consulting business model can be combined with other business models
to offer clients a comprehensive technology service.
Hence, the best knowledge of the technology platforms in place (or to be
implemented), and excellence in the analysis and extraction of information
and conclusions, or the scope and complexity of the project, are decisive
characteristics that affect an organisation's decision to outsource management
or stages of implementation.
Consulting work is normally formalised through open or closed contracts.
In open contracts, the relationship begins when a specific service is
commissioned and, depending on the result of this service, the contract may
be extended with the commissioning of new services. For example, open
contracts may be used for the execution of one or more stages of the project.
GNUFDL " PID_00148382 105 Free software implementation, projects and companies
In contrast, closed contracts are awarded for the completion of a specific aim,
task, result or assignment and there is no direct possibility of extending the
contract in the same scenario. For instance, closed contracts may be used for
the independent auditing of a system, given that these tasks are carried out in
isolation and at specific points in time.
3.1.3. Installation and integration
The installation and integration business model is based on the direct
implementation of free software systems for users and organisations,
usually as part of free software projects.
In a way, this business model considers free software as the object of the
production of its services, rather than a product in itself. This creates a market
offering substantial benefits to clients:
" The organisation does not have to pay for licences for free software
products that are freely distributed so it can cut the costs of technological
implementation.
" The organisation does not need to practice product piracy and thus will
not breach the applicable legislation.
" The organisation can directly adapt the free solutions, thus cutting the
cost of the implementation of specialist systems.
" The organisation can adopt integrated direct implementation packages,
and hence reduce the risk of technological implementation.
A number of services can be offered under this business model, the main ones
of which are listed below, although this list is not exhaustive and does not
exclude other services:
(36)

the application, only the configuration of the components that can be
adapted to the specific features of the installation.

to integrate the diverse solutions we wish to install. When the same
software needs to be implemented on a series of computers with identical
hardware, it may be useful to use pre-configured image distribution and

and efficacy of the process.

servers or a work station, among others. The redistribution of integrated
software is subject to the licences of the specific solutions. Appendix I
describes the main free software licences and their compatibilities.
As we can see from the above classification, these services are closely related
to the stages of free software solutions analysis and of implementation
and migration of the implementation project described in the second unit.
Hence, a better knowledge of the technology platforms and excellence
and efficiency of services or the scope and complexity of the project are
decisive characteristics affecting an organisation's decision to outsource the
installation and integration of its system.
3.1.4. Systems migration
The systems migration business model is based on transferring the
operating function from the system in place to the system to be
implemented.
GNUFDL " PID_00148382 107 Free software implementation, projects and companies
Migration is a complex process that must be carried out with accuracy
and rigour, since the data and configurations we are dealing with are the
organisation's capital.
The diversity of situations encountered by companies that migrate systems are
the result of a combination of the source and target platforms of migration.
A thorough knowledge of the platforms and experience in migration are the
basis for offering added value to clients.

that require tuning or virtualisation.
The complexity and scope of migration, the ability to carry out the process
carefully, efficiently, effectively and as quickly as possible, and the best
knowledge of the source and target technology platforms of the migration
are decisive aspects that can persuade organisations to outsource migration of
their systems.
As we can see from this classification of services, the migration process may
need other services, such as installation, configuration, integration or testing
to ensure that we meet our aims.
Free software uses and promotes open standards for interoperable data
exchange and its role in systems migration is particularly important. For
instance, starting off with a system that does not store data in open standards
could complicate migration because of format conversion, especially if
the original is privative. Appendix II of this module introduces the open
standards, defining them and the organisations behind them, and offers some
examples.
GNUFDL " PID_00148382 108 Free software implementation, projects and companies
3.1.5. Systems administration and maintenance
The systems administration and maintenance business model involves
carrying out management and monitoring tasks for a system already
implemented and operating.
The main aim of the services offered under this business model is to keep the
entire system up and running, adapting the configuration to changes, solving
any problems that may arise and repairing malfunctions that affect the normal
operation of the organisation.
The following list indicates the main services offered under this business
model, although it is not exhaustive and does not exclude other services:

" Administration: consists of providing basic management of the system,

implementation of new functionalities and the evolution of the system.
Many administrative system tasks can be carried out remotely40.
" Maintenance��and��evolution: consists of supervising, monitoring and
redressing issues in the system that could affect its operation, together
with the control and evolution of the obsolescence of its components.
Examples include malfunctions and the deconfiguration of hardware or
software, the control and updating of software versions, and the evolution
plan for the hardware and software.
" Security: this consists of managing the security of the system, controlling
risks, maintaining policies for prevention, contingencies, diagnosis and
debugging. Examples include backups or the control and maintenance of
keys and certificates.
Given the characteristics and features of these services, many organisations
decide to keep staff on for these tasks, but some small and medium-sized
organisations are unable to create such a position.
The outsourcing of some services, such as intranet and extranet servers, can

GNUFDL " PID_00148382 109 Free software implementation, projects and companies
3.1.6. Support and training
The support and training business model involves providing
professional technical assistance for the technological training of users
and the resolution of issues and problems relating to use of the system.
The implementation of free software systems may initially require user
support and training measures, particularly if the previous system was based
on privative software. As we saw in the second module of this subject, the
implementation project must take into account the need for user training
in order to promote positive change management, whose features make it a
service that can be easily outsourced to companies specialising in this sector.
The following list indicates the main services offered under this business
model, although it is not exhaustive and does not exclude other services:

" Support: this service provides technical assistance to users in order to

centres, but it can be a good idea to provide e-mail addresses for resolving
issues or instant messaging with professionals. It can also be convenient
to combine these tasks with those of the systems implementation project
in order to fix possible bugs in the implemented software.
This business model generally requires human, technological and material
resources adapted to the aims of the training:

a free software company,
as in the case of Cometa
Technologies, which we shall
see in the second section.
Taking into account this definition, the aims of the business plan will be as
follows:
" To conduct a market study to position the business plan and determine
its technical, economic and financial viability.
" To develop the measures required to achieve the aims set out in the
business plan.
" To monitor the evolution of the company and analyse deviations from
the initial business plan.
" To serve as a calling card for the project and the business entrepreneurs in
order to obtain the financing and support of third parties.
Although the first three aims are mainly internal, the last is external and
visible by people who do not form part of the project, in theory at least. When
drafting our business plan, we always need to consider this dual aim: to act
both as a plan for the project and as the presentation of the project.
Naturally, we need to avoid falling into the trap of omitting the risks or
negative parts of the project to make it look more attractive to investors. In
fact, missing out these elements could be detrimental to our business project
because it would be based on false suppositions. A true picture of the technical
and economic aspects is thus one of the basic requirements for drawing up
a business plan.
Any business plan needs to respond to a series of questions about the project
we wish to introduce: Who?, What?, Why?, Where?, When? and How much?
" Who?
GNUFDL " PID_00148382 111 Free software implementation, projects and companies
The name of the company, the brand of the products or services offered,
the names and track record of the business developers.
" What?
The description of the products or services offered, the markets at which
they are aimed and the market share set as the target, among others.
" Why?
Every business plan generally seeks to obtain and maximise profits.
However, this is not incompatible with other aims, such as improved
quality of life in society or the creation of jobs.
" Where?
The geographical area where the products or services are to be marketed,
which can be regional, national or international. The distribution
channels that will be used, including possible agreements with other
companies who will allow entry to other regions.
" When?
The expected start of business and subsequent planning, including
temporary conditions or limitations that could affect the company, such
as procedures for obtaining licences, production time, obsolescence of
certain technologies or seasonality.
" How��much?
The initial investment needed to launch the business project, the
minimum and desired turnover, the threshold of profit and loss, the
reinvestment of profits and the sharing of dividends, among others.
These issues are covered in the following aspects, which are found in almost
any business plan:
" Executive summary
" Introduction
" Business description
" Organisation of production
" Internal organisation and human resources
" Market study
" Marketing plan
" Financial analysis
" Legal form
" Risk management
" Summary and evaluation
GNUFDL " PID_00148382 112 Free software implementation, projects and companies
Depending on the nature of the company or business, these aspects will have
a greater or lesser importance in the business plan and may be organised in
different ways.
The following sections will discuss each of these aspects and study their
relationship with the free software business models we saw in the previous
section.
3.2.1. Executive summary

In all events, the executive

of the business plan and summarises the main points of the document.
It gives potential investors a comprehensive idea of the business plan
without having to go through the various sections in detail.
The executive summary should cover almost all of the points of the business
plan, which are:
" Description of the business model, with a particular emphasis on the chain
of value and source of income.
" Short description of the project developers, their training, knowledge and
skills, professional track record and dedication to the new project.
" Concise description of the market, including size, clients, growth potential
and barriers.
" Analysis of the functional areas of the project: production, quality and
organisation of human resources.
" Summary of the financial analysis of the project and the investment
required to set it up.
" Summary of the risks of the project and the plans to prevent them and
remedy their consequences.
Obviously, the executive summary should highlight the strong points of the
business plan, particularly for the business model we wish to adopt, the
strategy that we will use to do so and the team developing the idea.
We recommend writing this part after completing the business plan and to do
it from scratch, that is, without re-working texts that we have already written.
GNUFDL " PID_00148382 113 Free software implementation, projects and companies

professionals involved in the drafting of the business plan.
As we have seen, the presentation of the team of developers should cover
the professional career of each of its members and the knowledge they will
bring to the business project. More often than not, the team of developers will
have members with a profile specialising in business management and others
specialising in specific technological areas, as is the case of companies that
work with free software.
Lastly, the introduction should provide a brief description of the different
sections of the business plan that will be developed later.
Mission and vision
The introduction is the place to describe the mission and vision of the new
company because it allows the reader to see how these two concepts are
developed in the business plan.
The mission and vision of an organisation are a concise definition of its main
features and aims, and its strategies for meeting the latter.
The mission is a short phrase justifying the existence of the
organisation, i.e. the basic aim of its activities and the values guiding the
activity of its employees. The mission is closely linked to the internal
values of the organisation and basically describes how to compete and
generate value for customers.
The vision is also a concise phrase describing the medium- and
long-term goals of the organisation. It is addressed to the market and
should offer an expressive and visionary angle on how the organisation
wishes to be seen by the world.
The main differences between the mission and vision can be summarised as
follows:
" The mission describes the internal aspects of the organisation and its
operation, while the vision describes the external aspects.
" The mission has a short- to long-term time horizon and highlights the
aspects that should be put into practice immediately in the organisation,
GNUFDL " PID_00148382 114 Free software implementation, projects and companies
while the vision is fixed in the medium- to long-term and gives the general
lines of the future evolution of the organisation.
Corcaribe Tecnolog�a and eZ Systems
The company Corcaribe Tecnolog�a specialises in products and services based on free
software and has the following mission:
"Corcaribe Tecnolog�a provides technological solutions that generate added value with
a business model that allows us to offer the best cost for results delivered to our
clients, producing authentic tangible and intangible benefits for our members and
collaborators."
And the following vision:
"To become a Latin-American reference of continued success in the implementation of
integral technological solutions, applying the principles and values of free knowledge in
a model of sustainable development."
Similarly, eZ Systems, which provides free content management software sets itself the
following mission:
"To be the leading content management platform by 2012."
And the following vision:
"To help companies to manage, publish and share information."
It is not essential to define a mission and vision in the business plan, but it can
help to summarise the short-, medium- and long-term aims of the business
project and to convey them effectively to potential investors.
3.2.3. Description of the business
We recommend you should begin this section with a description of the
company you wish to set up and a brief presentation of the project developers,
even if you have already done so in the introduction.
The main aim of this section is to describe the products or services for
which you are drawing up the business plan and the business model
adopted to offer them, as we saw in the previous section.
Special care should be taken when explaining the features of business models
based on free software since the reader of the business plan will not necessarily
be familiar with them. This includes aspects of the protection of intellectual
property and rights over products and services.
It is also a good idea to describe the needs that will be met by the products or
services and point out the main differences with the existing offer, in order to
show that the business project is well positioned in the market.
GNUFDL " PID_00148382 115 Free software implementation, projects and companies
Lastly, we will need to indicate the capacity for the production and provision
of services, which will serve as an introduction to the next section on the
organisation of production.
3.2.4. Organisation of production
The section of the business plan on the organisation of production
describes the technical tasks of the future company.
This far, we have looked at the business plan from the point of view of
describing the marketing of new products and services, without distinguishing
between them. Now, however, this section of the business plan will take one of
the following forms, depending on whether it concerns products or services:
" If the company business is the development, production and subsequent
marketing of a product, we need to detail the development and production
phases.
" If the company provides a service that does not involve a production
process, the procedures for provision of the service and the technical needs
should be described in detail.
It goes without saying that the two options are not mutually exclusive and
a business plan can contain both. For example, a company might specialise
in the migration of systems to free software but also provide training in free
software technologies to users and technical staff.
Generally speaking, a business encompassing the phases of research,
development and production will be much more complex and involve greater
risks:
" Research��and��development��phase. When describing the research and
development phase, we need to pay special attention to the estimated
duration of the research and development phase and the necessary
investment in human and material resources.
In high technology sectors in particular, as is the case of free software, the
business plan must evaluate the human resources skills and know-how
needed for the successful completion of research and development tasks.
This section should also detail the distribution of roles and duties, the
risks inherent to all research and development activities, the potential
synergies between projects, the process of innovation and continuous
product improvement and how this process will be integrated into the
production process.

In all events, remember that you should always explain the advantages and
disadvantages of the various alternatives and justify each of your decisions.
3.2.5. Internal organisation and human resources
This section of the business plan details the organisation of the team
needed to develop the business project and the profiles required for it.
(47)

or sales director, we can come across roles such as community director, the
person who manages relations with software developers and users, or director
of cooperation projects, who manages and coordinates projects developed in
collaboration with other companies, research centres or universities.
3.2.6. Market study
Market studies are an essential part of business plans and hence one of
the keys to its success.
A good market study will help us to assess the technical and financial
feasibility of the business project correctly and to identify potential
clients and competitors in order to come up with the right strategy for
marketing the products or services detailed in the business plan.
When drafting a business plan, it is useful to conduct the market study first,
at least as a rough version, because its results can affect various parts of the
business plan.
Thus, the market analysis needs to provide information on the following
aspects:
" Current��market��situation. We must first segment the market according
to the most relevant features of the business plan and determine its size
together with its past evolution. We will also need to determine the
decision-making process of the market and the behaviour of its customers,
particularly their reaction to the launch of new products or services.
Secondly, we need to evaluate the needs that may arise as a result of the
introduction of the products or services proposed in the business plan.
This depends largely on whether the product or service offers something
new and on our ability to influence customer habits.
" Market��growth��forecasts. Once we have established the current status
of the market, we need to be able to predict its future evolution. Is this
GNUFDL " PID_00148382 118 Free software implementation, projects and companies
market developing, stable or declining? How fragmented is the market? Is
the market becoming concentrated?
Again, we need to take into account the potential influence of the new
products or services on the market. For example, the introduction of
solutions based on free software can effectively change the market because
they encourage the formation of a new sector specialised in free software.
" Identification��and��classification��of��clients. One of the primary aims of
market analysis is to discover who the potential clients of the proposed
products or services are. The task of classifying the diverse types of
client based on common features is also very important because it
allows us to define different strategies for each. For example, a company
that implements free software systems in companies will present itself
differently to clients depending on whether it is a family business or a
major corporation. We also need to remember that a product or service
may be offered to clients who are theoretically different. The flexibility
and interoperability of free software encourages this type of action.
Moreover, we need to evaluate each type of client's reception of the
product or service. Continuing with the previous example of a company
that specialises in the implementation of free software systems, a major
company with dedicated technical staff may be more reluctant to use free
software, partly because of the fear of change, whereas a family business
might be more receptive.
Lastly, if the future company already has a client portfolio or has clients
who have expressed an interest in its products or services, this can be
included in the market study.
" Analysis��of��the��competition��and��its��products. A market study should
reveal the competitors of the future company and identify their strengths
and weaknesses as well as those of the products or services they offer.
We must indicate the characteristics of their products and services,
including price and quality, and their market share and sales strategy. It is
very important to identify the market leaders for each of the products or
services covered in the business plan.
We should also be careful not to disregard potential competitors, i.e.
companies that are not yet on the market but which could enter, or
companies from other geographical regions. In our current climate,
particularly in information and communication technology sectors, as is
the case of free software, the competition tends to be global and many
companies can offer their services directly or indirectly from any location.
" Analysis��of��barriers��to��market��entry. Barriers to market entry are
obstacles that companies come up against when they enter a new market,
such as the need for major investments in the case of new companies
or the lack of an established brand. An example of this is that free
software tends to suffer from a perceived lack of quality in contrast to the
proprietary software companies and solutions already on the market.
GNUFDL " PID_00148382 119 Free software implementation, projects and companies
In the same way, however, we can also study which barriers to entry
we should focus on once we are on the market in order to keep the
competition at bay.
" Influence��of��governments. The market study should discuss the way
in which local, regional, national and international governments can
influence the market and, hence, the viability of the business plan. For
example, governments can act both as market regulators and as providers
and clients.
This is particularly true in the case of free software, which, as we have
seen throughout this subject, is a point of interest for many governments,
including the regional government of Extremadura and the Federal
Government of Brazil.
Market studies need to be planned carefully because they involve a
number of phases, which can be summarised as follows:
 Collection of general information, by which we obtain a large volume
of data on the market under study.
 Analysis of the information obtained.
 Selective search for information to obtain the missing information
required to complete the market study, which will have been identified
in the previous analysis.
To conduct the market study, we will need a great deal of information
and this is not always easy to obtain. There are countless bodies and
sources of information, both general and specialised in specific regions
and sectors: governments and national statistics institutes, local and
regional governments, private bodies such as chambers of commerce and
business associations, journals and specialist publications.
A good market study should conclude with a strategic analysis49 that
relates the results of the study to the description of the business and
planned resources, and that also highlights the potential of the business
plan.
(49)
This analysis can also be supported by the use of strategic tools such as SWOT
analysis ( http://es.wikipedia.org/wiki/An%C3%A1lisis_DAFO ) or Porter's Five Forces (
http://es.wikipedia.org/wiki/An%C3%A1lisis_Porter_de_las_cinco_fuerzas).
3.2.7. Marketing plan
The purpose of the marketing plan is to define the commercial strategies
that will enable us to reach the predicted turnover of the financial
analysis, which we will look at in detail in the following section.
Hence, the marketing plan details the actions we need to take in order to apply
the business model and opportunity described in the business plan and to
exploit their competitive advantages.
GNUFDL " PID_00148382 120 Free software implementation, projects and companies
Thus, the marketing plan needs to take into account the following:
(50)
" Overall��commercial��strategy. The overall strategy needs to define how

undergone by free software.
clients be interested in or decide on the products or services we offer, and
hence, which features of our products or services we will emphasise to
generate sales, such as price, quality, guarantee, technical support, etc.
Free software is a prime example of this, since its main attraction for
potential clients is the reduced costs it generates rather than its quality,
which is often superior to that of proprietary software. In contrast, clients
usually identify the high prices of proprietary software with superior
quality, and free software, which is more economical, with inferior quality.
Hence, when drawing up a business plan based on a free software business
model, it is essential to emphasise the superior quality of50 free software.
" Sales��strategy: defines the short- and long-term sales aims and the market
sectors in which the products or services offered will be introduced
initially and in the long run. In all events, decisions must be justified and
backed up by the results of the market study.
(51)
" Price��strategy: first of all, we must determine the prices at which the

products or services will be sold, comparing them, if possible, with those of
those of the competition, if you
have access to this information.
the competition, estimating a gross profit margin and evaluating whether
this is sufficient to sustain the company's entire business activity51.
It is very important to justify the price policy, especially when comparing
it to that of the competition. If the price of the products or services offered
is higher than that of the competition, this should be explained in terms of
innovation and quality, features and enhanced guarantees. If the price is
lower, we will need to explain how we will make it profitable (for instance,
greater efficiency and lower production costs). Again, it is very important
to explain the reasons for the low cost of free software and the benefits
that this brings.
Lastly, the price strategy should be optimal, i.e. it should maximise the
profit margin, and hence, profitability. A higher price can sometimes
generate greater profits, even though it partially reduces sales.
" Sales��policy: this determines the composition, form of contract and
profile of the sales team, including representatives, at the launch of the
company and in its medium- to long-term evolution. It includes the sales
margin policy and the promotional measures that will be offered to sales
representatives and authorised distributors.
The sales policy also includes: estimated sales for each sales representative,
incentives, the collection periods agreed with clients, and special
promotions such as discounts, advances, rebates, etc.
GNUFDL " PID_00148382 121 Free software implementation, projects and companies
" Promotion��and��advertising: you should describe the measures that will
be taken to attract the attention of potential clients to the products or
services offered. These measures include mass e-mailing, participation in
trade fairs and events, advertising on websites, etc.
We will eventually need to quantify the cost of the promotion and its
return through consultations with clients and the sales we have closed.
" Aftersales��service��and��guarantees: you should describe the aftersales
service and the guarantees of the products or services, where applicable. In
other words, what type of service and guarantee are offered, their duration
and price (if optional) and their cost for the company.
With free software, part of the aftersales service is indirectly provided
by the community of developers and users, which constantly improve
successful products. The free software company plan should keep this
in mind and explain it as an advantage, but never as the only form of
additional support. Remember that the vast majority of clients would like
the aftersales service to be included and guaranteed in the conditions of
sale.
Lastly, we also need to assess the impact of our aftersales service and
guarantees on the client's final decision and compare our service with that
of the competition.
(52)
" Distribution�� policy: the distribution policy should describe the

partners/join-openbravo/details/.
In free software business models, we often come across programmes
for partner companies52 in different forms: system integrators, software
vendors, etc., and those who are paid commission and offered dedicated
services and assistance and access to promotional channels.
As we explained above, free software products and services can easily
be offered on the global market, so the marketing plan must study this
possibility and its potential features, including the effect of international
laws on the company's activity, overseas collection management, etc.
3.2.8. Financial analysis
The financial analysis or study is also one of the essential parts of any
business plan, since its aim is to evaluate the feasibility and financial
potential of the business project, detect the investment needs for
its launch, identify the resources available initially and describe the
various possibilities of financing.
GNUFDL " PID_00148382 122 Free software implementation, projects and companies
Contrary to what we may think, the financial analysis is one of the most
creative parts of drafting a business plan.
The financial statements or main headings that need to be covered by the
financial analysis are as follows:
(53)
" Cash position over the first year, broken down by months to reflect the

the company.
" Calculation of the balance point and alternatives if target sales are not
reached.
" Financing needs and alternatives, selecting those that are most profitable
and including elements to explain the decision.
" Annual balance sheets with a five-year view and the first year broken down
by months.
" Source and application of funds, allowing us to predict risk situations for
the company and evaluate the source and long-term use of funds.
Working capital
Working capital measures an organisation's balance of assets and liabilities and confirms
that there are more liquid assets than short-term debts. For more information, see
http://www.innovaceei.com/es/knowledgebase/index.asp?faqsRecid=385&faqRecid=385&show=4460.
Combined analysis of these financial statements is recommended as we can
draw conclusions about the business project as a whole: the amount of capital
required and when it will be required, and the necessary debt and when it
should be paid, among others.
We should also explain the expected return on our investment and indicate
when this will be recovered.
As explained above, we need to avoid falling into the trap of presenting an
overly optimistic financial analysis to investors in order to win them over,
since this will go against the company sooner or later and question marks will
be raised about its viability and credibility.

of the first unit.
Risks can be classified as internal (originating in the company) or external and
by the functional area that they affect: technical, commercial, etc.
For example, internal risks can include delays in production or a lack of
qualified staff, while external risks can be a new market regulation that
partially reduces return or the emergence of new technologies that cause the
products or services offered to become obsolete.
(55)
We need to define a contingency plan for each risk, which includes a series of

The correct identification and assessment of risks in a business project and the
drafting of suitable contingency plans for them, far from highlighting project
weaknesses, actually emphasise the management skills and precaution of the
business developers and enhance their credibility.
GNUFDL " PID_00148382 124 Free software implementation, projects and companies
3.2.11. Summary and evaluation
The last section of the business plan should summarise the
strengths and weaknesses of the business project, the advantages and
opportunities it offers and its main risks and threats.
The summary is your last chance to persuade a potential investor so you need
to be very convincing and seize the opportunity to emphasise the arguments
in favour of the business project and those that its developers believe in.
However, after drafting the business plan, the project developers may find
that it will not be as profitable as they had hoped or even discover that it is
completely unfeasible. This shows how useful the business plan is as a tool to
identify the best business opportunities.
3.2.12. Business plans and free software
Drafting a plan for a free software business is not that different to the
procedure for drafting business plans in other sectors and we have already
seen some of its features in the previous sections.
In general, we need to remember that a business plan may address different
types of reader: advisors, investors, technicians, bankers, etc. Therefore, we
need to use a language that they can all understand and avoid using highly
technical vocabulary. When the use of technical terminology is unavoidable,
you should explain each concept clearly in simple terms. Investors never
invest in anything that they do not fully understand.
We also need to take the time to explain the features of free software, pointing
out the differences between it and proprietary software, and highlighting its
main advantages. Do not hesitate to use real-life examples and examples of
success to back up the arguments put forward in the business plan.
Although free software is adopting an increasingly relevant role in the media
and society thanks to the commitment of the free software community,
companies and government bodies, its nature and financial implications are
not so well known.
Again, we must take the time to explain the free software business models
carefully and be prepared to answer and possibly even anticipate the most
common questions, such as, How can you invest in and earn money from
something that anybody can copy?
GNUFDL " PID_00148382 125 Free software implementation, projects and companies
3.3. Production of free software
Many of the business models described in the first section depend to a greater
or lesser extent on free software development.
One of the problems with free software projects is that only the successful
projects are echoed in the community and only the very successful ones reach
the non-specialist media.
However, before we turn to look at free software production, we should
remember that the vast majority of free software projects are a failure for
specific reasons. It may simply be that the project fails to produce quality and
competitive software or that it does not manage to attract the attention of the
community of developers and users.
Needless to say, as we saw in the subject materials, a free software project
should be dealt with as a software project and only in the last instance, as a
simple engineering project. Hence, a free software project will pose the same
initial risks and problems as any other project.
However, given the free nature of this type of project, there are other strengths
and weaknesses to take into account. Due to the seemingly non-professional
nature of many free software development projects, their execution may
appear easier than traditional software development projects, but there can
be nothing further from the truth.
The aim of this section is to describe the features of free software development
projects, contrasting them with proprietary software development and
offering a series of good practices to encourage their success. These practices
correspond to the key areas and elements required to set up and execute a free
software project, namely:
" Creation and presentation of the project
" Necessary infrastructure
" Organisation of the community
" Development
" Releasing and packaging
" Choice of licences
Naturally, not all of these steps are compulsory. As we saw in the business
models, a free software company might initiate a project or, as occurs in most
cases, it might join an existing project.
GNUFDL " PID_00148382 126 Free software implementation, projects and companies
This last option is often the most advisable and, given the nature of free
software, it does not rule out the possibility that a new project could be created
from an existing one under the identity of the company or organisation
interested in leading the development.
3.3.1. Creation and presentation of the project
This section deals primarily with the steps required to create a new free
software project and present it to the community.
Thus, the first step to take before creating a new project is to find out whether

http://www.sourceforge.net.
If we decide to create a new project, the first thing we should do is choose a
name that will identify it in the community. Generally speaking, a good name
will give an idea of what the software does or at least its field of application,
and it should be easy to remember.

are still available.
As we saw in the section on the creation of business plans, all projects must
have a clear definition of their mission that will attract the attention of users
and developers and let them decide whether or not they are interested in the
project.
Along with our mission, it is important to state clearly that the project
concerns free software, which means making a clear reference to free software
or open-source software).
Other key elements in the presentation of a free software project are:
(59)
" List��of��planned��functionalities59��and��current��requirements. This should

find out easily whether it has the functionalities that they are looking for.
GNUFDL " PID_00148382 127 Free software implementation, projects and companies
The requirements should also be easy to understand so that users know
whether the application can be installed and used on their system.
" Development��status. In the free software community, users are usually
very interested in knowing how the project is coming along, both if it
is a new project and if it is an older one. Thus, we should explain the
short- and long-term aims of the project, and the functionalities currently
being developed and that will be available in future releases, etc.
(60)
" Available��downloads. The source code should always be downloadable

avoid user registration processes

complicate the process for the user60.
The installation process should also be simple and, most importantly,
comply with the standards from the very start. It is not initially necessary
to provide binary packages or executables unless the compilation process
is very complicated.
" Development��repository. Unlike users, potential developers are more
interested in accessing the working repository, where they can follow
the day-to-day evolution of the project and participate in it, either by
adding new functionalities or fixing bugs. Thus, it is a good idea to allow
everybody anonymous read access to the repository.
(61)
" Bug��tracking. As with the repository, the bug tracking61 database should

terms bug tracker and bug
also be open to everybody. Paradoxically, the more bugs the project
database.
database contains the better because this means more users and more
participation in the project.
There won't be many bugs at the start of the project. It is good practice to
log any bugs fixed internally by the project team in the database.
" Communication��channels. One of the aims of any free software project
is to create a community around it and, in order for this community to
organise itself, we need to facilitate the right communication channels.
This includes mailing lists, IRC channels, forums, etc.
In the first phase of the project, it is wise not to diversify or specialise the
communication channels too much. A single forum or distribution list for
users and developers may be sufficient to encourage interaction between
them.
" Documentation��for��users��and��developers. Documentation is essential
for any free software project, for both users and developers.
Good user documentation needs to explain how to install the software
and how to use its functions. You can also provide users with a basic
tutorial, containing a step-by-step explanation of how to perform the most
common tasks. Maintaining a section of frequently asked questions or
FAQs is the perfect complement to the documentation.
GNUFDL " PID_00148382 128 Free software implementation, projects and companies
Developer documentation should include the contact details of the main
project developers, instructions for sending error reports and patches, and
a presentation of the development organisation and the decision-making
process used by the developers.
We will look at all of these elements in detail in the following sections.
To conclude this section, we would like to emphasise the importance of
appearance  that is, how the free software community sees the project  for
the success or failure of a free software project.
Many developers neglect this communicative and public relations task, but it
forms an essential part of virtually any successful free software project.
For this purpose, we will need to clearly define the aims of the new software,
which can usually be summarised as:
" To��explain��clearly��what��the��software��does: its main functionalities, the
current state of development and future plans, and its positioning vis-ą-vis
existing solutions and projects.
" To��raise��the��profile��of��the��software: ensuring that it reaches the
community or market of potentially interested users and developers.
" To��promote��the��use��of��the��software: ensuring that potential users and
developers know how to use the new software and adopt it instead of the
alternative solutions.
" To��involve��new��developers��in��the��project: allowing them to contribute
to the development of the project through the implementation of new
functionalities and to state their opinion on the future direction that the
project should take.
These last two aims, obtaining lots of users and lots of developers, are often
the most important ones. However, we need to implement one strategy for
users and another for developers since, while they form part of the same free
software community, they represent two very different audiences.
We need to clearly define the message we wish to convey to each and structure
it with a gradual complexity to ensure that the level of detail corresponds to
the effort required by the reader. For example, there is no sense in saturating
the user with software architecture or explaining technical details to the
developers without first giving them a reasonable overview of the architecture.
GNUFDL " PID_00148382 129 Free software implementation, projects and companies
Finally, this message should be easily accessible, reaching its audience through
advertisements on forums or related communities, on the project website or
even in the documentation, among other options.
3.3.2. Infrastructure
All free software projects need a series of tools to manage the
information generated daily by the project, from the developed code to
communication among its members.
We introduced some of these tools in the previous section because they are
needed to implement the project:
" Website
This provides a centralised source of information about the project and
offers access to other specialist management tools.
" Mailing��lists
This is one of the most common channels of communication in free
software projects. Message exchanges are usually archived and used as
reference and to form a knowledge base for the project.
" Version��control��system
This allows developers to control the creation and management of the
code, returning to previous versions and merging different versions. With
the version control system, anybody can visualise the current status of the
code and its evolution over time.
" Bug��tracking��system
This allows developers to track the functionalities and bugs they are
working on individually and to coordinate themselves and plan new
releases. Although bug tracking is its main function, the database can also
be used to track any project task, such as new functionalities.
With the bug tracking system, anybody can find out if a bug has been
fixed or if it is being worked on. In conjunction with the version control
system, it tells us about the dynamism and logged activity of the project.
" Chats
These are a communication channel for solving queries and problems
quickly. Conversations are not generally archived so it is better for
complex discussions to take place on mailing lists.
Each of these tools responds to specific needs, mainly connected
with communication and information management. The experience and
characteristics of the community of users and developers associated with the
GNUFDL " PID_00148382 130 Free software implementation, projects and companies
project will dictate the configuration and use of these tools. Nonetheless, it
is worthwhile pointing out a few aspects that could be useful in most free
software projects.
Mailing lists are an essential part of any free software project so we need to pay
special attention to our management and use of them. It is virtually a must
to have a management system for distribution lists, whose configuration and
maintenance could be complicated in the early stages.
Internet resources
The most popular systems include Mailman ( http://www.list.org ), Smartlist
( http://www.procmail.org ), Ecartis ( http://www.ecartisorg ), Listproc (
http://listproc.sourceforge.net ) and Ezmlm ( http://subversion.tigris.org/hacking.html ).
The main options and functionalities of a distribution list management
system are as follows:

or once a month, while in normal

" File management and querying
Mailing lists can also be integrated into other tools, such as the version control
system or the bug tracking system, to inform of aspects such as source code
changes or modifications to the error status or tasks in course.
The version control system is also essential for any free software project that
hopes to create a developer community. Almost all version control systems
operate through the existence of a remote copy, common to all developers,
whose versions can all be consulted. Each developer has a local copy of this
remote copy that he or she works on. Occasionally, the developer sends his or
her modifications to the remote copy to share them with others.
The main functionalities of version control systems are:
" Committing: integrating the changes from the local copy to the remote
copy, which will then be logged in the version control database.
" Updating: integrating the changes of the other developers in the local
copy.
" Checking��out: obtaining a local copy from the remote copy.
GNUFDL " PID_00148382 131 Free software implementation, projects and companies
Any document or file edited in the project can and should be subject to version
control, which should not be limited to source code files. The use of a version
control system can be very practical for editing and sharing documentation
and technical reports and generally any document created and maintained
jointly.
As explained above, the bug tracking system has many other functions besides
that suggested by its name. These include the tracking of all types of task, such
as the implementation of new functionalities, the preparation of releases and
user support.
The life cycle of a bug is usually as follows:
" The��bug��is��reported: All bugs include at least a summary and initial
description containing, where possible, the elements needed to reproduce
it. Most bug tracking systems allow us to set up specific fields. Remember
that bugs can come from both the community of users and the community
of developers.
Once archived, the bug status remains open and is not assigned to
anybody. During this time, the individuals who access the database can
read the bug description and ask the user or developer who reported it for
more information.
" The��bug��is��reproduced: based on the instructions in the bug description,
somebody manages to reproduce the bug, thus validating it. In other
words, we can now say that the bug is real.
" Bug��diagnosis: in the previous phases, a developer takes responsibility for
fixing the bug or somebody in an authoritative position in the project
assigns it to the most suitable developer.
" Bug��assignation:
this must be entered in the database so that we do not have more than
one developer working on fixing the same bug without realising it. It is
also possible to report the expected fixing date or release in which the bug
will have been fixed.
" Bug��fixing: once the developer has fixed the bug, he or she will mark it
as fixed or closed.
Bugs can sometimes be fixed quickly, so some of these phases may not be
necessary. Sometimes, the bug is not really a bug and may simply be caused
by incorrect use. In all events, no matter how easy the solution is, it is always
a good idea to log the bug and report it correctly to users.
GNUFDL " PID_00148382 132 Free software implementation, projects and companies
Another common situation is when several users report the same bug, referred
to as duplicate bugs. In this case, it is best to group all of the reports into one
so that we can concentrate our efforts and put all of the information in the
same place.
Lastly, a bug may be reported as fixed when it has not actually been resolved,
generally because the steps followed to reproduce it do not match those
indicated by the user who reported the bug. In this case, the user can reopen
the bug, adding all of the necessary information. There are numerous public
forges offering these and other tools, ready for use in free software projects.
These platforms come with a series of advantages and disadvantages.
Internet resources
The most popular public forges include SourceForge ( http://www.sourceforge.net ),
Savannah ( http://savannag.gnu.org and BerliOS.de ( http://www.berlios.de ). Some
organisations also offer hosting for projects in their area of interest, such as Apache (
http://www.apache.org ) and Tigris ( http://www.tigris.org ).
Their advantages include their capacity and available bandwidth: the success
of the project is irrelevant because the servers will always be in operation.
Keeping a high-availability server running requires a lot of extra work.
Moreover, the tools available on these forges have already been configured and
are usually very easy to use. Obviously, the main disadvantage is the limited
flexibility and configuration possibilities of the tools.
So, before starting our project, we may want to host it on a public forge
but be open to the possibility of our own hosting in the future, starting by
registering the name of the domain associated with the project. For example,
while not the perfect solution, having a website informing about the project
that redirects to a public forge for aspects of code development can be a good
compromise.
3.3.3. Organisation of the community
One of the biggest differences between free software projects and proprietary
software projects is the way in which the developer community is organised.
In proprietary software projects, the structure is normally that of
a hierarchical organisation of the team or department in charge of
development in the company. Although hierarchies can sometimes be
seen in free software projects, partly due to the merits of the individual
developers, the organisation of the developer community is more
flexible and also stronger.
(63)
Paradoxically, one of the reasons why the developer community works as
This is known as forkability, i.e.
the possibility of forking.
one and remains close-knit is the possibility of creating a new independent63
project from the original project. The possibility of a free software project
GNUFDL " PID_00148382 133 Free software implementation, projects and companies
forking is usually negative for both developers and users. It is precisely this
threat that makes the community organise itself and strive to ensure that
decisions are taken as a group.
In other words, the possibility of forking makes the community strive to
achieve a more or less democratic consensus in major project decisions.
There are generally two forms of organisation for free software communities,
although most projects end up adopting a position midway between the two.
They are:
" Organisation��based��on��a��"benevolent��dictator".
A benevolent dictator is a figure of authority who makes final decisions
with repercussions for the development of the project. Nonetheless,
benevolent dictators often do not make decisions directly but act as
moderators in discussions, attempting to conciliate the viewpoints of
the developers and identify the most valuable contributions. Another
of the actions of the benevolent dictator is to delegate experts to deal
with the decisions or discussions underway. Benevolent dictators are
usually developers with sufficient experience in the project and related
technologies. However, they do not need to be the most expert developers;
they must simply be capable of understanding the project as a whole and
recognising the best contributions.
" Organisation��based��on��consensus.
The term consensus is used to refer to agreements accepted more or less
tacitly by the entire community, i.e. where nobody opposes the decisions
or the direction taken by the project. As a result, the process of consensus
is not usually formal by any means. However, if a consensus cannot be
reached on a given issue, a vote can be taken.
Most discussions that take place during the development of a project are
usually technical, so consensus is achieved when everybody agrees on
an issue, such as the design or implementation of a functionality or the
way to fix a bug. In these cases, a member also usually summarises the
discussion at the end.
Generally all communities, particularly those based on consensus, have
excellent support in the version control system, which means that they can
go back and undo any decision that turns out to be incorrect.
Projects usually begin with an organisation based on a benevolent dictator and
evolve towards an organisation based more on consensus as the community
expands. This usually occurs at certain times in the development of the
project, such as when a benevolent dictator gives up his or her position and
the authority is distributed across the community, particularly among its most
highly regarded members.
GNUFDL " PID_00148382 134 Free software implementation, projects and companies
After a time, the conventions and agreements adopted through consensus by
a community can become increasingly large, so the main points should be
set down in a document that can be used as a guide and for future reference.
This may include both the form of governance of the community and the
conventions and recommendations for developers.
Internet resources
Take a look at the guides for the Subversion project
( http://svn.collab.net/repos/svn/trunk/HACKING ) or the Apache
foundation ( http://www.apache.org/foundation/how-it-works.html and
http://www.apache.org/foundation/voting.html ).
Lastly, we need to ask ourselves what role can companies play in free software
communities.
On the one hand, we could have a company that wishes to start up a free
software project and create a community of users and developers. And on
the other, we could have a company that joins a free software project already
underway. In both cases, the company must clearly define its aims with this
free software project and know what its participation in the community will
be.
There are many possibilities. For example, the company may seek a leadership
position in the community and lead the project, or it may simply take part in
discussions, participate actively in the implementation of new functionalities
or have just a selection of its developers deal with the problems of its clients.
Bearing in mind the difficulties of constructing a successful free software
project, it is clear that, at least in the case of projects begun by companies,
the community already exists: it is formed by the developers in the company
and its clients.
In these situations, the benevolent dictator model will probably be the most
appropriate form of organisation, to start with at least, but we will still need
to define the rules for participation in the community. The challenge lies in
converting these clients into active users who will help to improve the project
and in getting other developers involved.
The solution, albeit a difficult one, is to offer benefits or some form of added
value to the users and developers who participate in the community.
It is good practice for the company's development team to be fully integrated
in the community and to follow the development methodology for the free
software project. This means that the developers must participate in the
project over a long period of time in order to become familiar with the
operation of the community and gain credibility in it.
GNUFDL " PID_00148382 135 Free software implementation, projects and companies
3.3.4. Development
This section describes the development process for free software projects,
not from a technical perspective, as this will depend on the nature of the
individual projects, but from the point of view of project management and
developer coordination.
With development, we need to remember that one of the differences
between free software projects and proprietary software projects is
the absence of a centralised organisation. For example, when the
date of a new release draws near, a company can assign a certain
number of resources to prepare for it. The voluntary developers forming
the community, on the other hand, are not so easy to direct. Their
individual reasons are different and while some may be interested in
publishing a new release on time, others may only be interested in a
specific functionality.
Thus, the distribution of tasks in a free software project is based mainly on the
independence between them, with the general rule being that each developer
works on what he or she wants when he or she wants.
Yet this approach is ideal in part, and a person or team is needed in most
free software projects to coordinate all the voluntary developers. This team
can be formed explicitly by the initiators of the project or the benevolent
dictator or implicitly by members with more experience and influence over
the community.
Some of the basic tasks of coordination, required to carry out the project
successfully, include:
" Delegating: one of the main tasks of the project coordinators is to delegate
tasks to other developers. When somebody delegates a task to another
person and the latter accepts it, the benefits are two-fold: the coordinator
finds somebody to do the work for him or her and this person's efforts
are acknowledged in the sense that they have been entrusted with a
task. Hence, the best way to delegate a task is through a channel of
communication that can be seen by the entire community, always giving
the option of turning down the offer.
In this case, the coordinator must be aware of the skills and interests of
the community members and direct the offers on this basis. For example,
there is no sense in asking somebody to do something if they lack the
necessary skills or if they already have several ongoing tasks.
" Criticising�� and�� praising: the correct evaluation of contributions
from each project developer is very important for the creation of
GNUFDL " PID_00148382 136 Free software implementation, projects and companies
a friendly atmosphere within the community. Moreover, evaluations
from coordinators or higher members have greater repercussions on the
community.
Hence, both criticism and praise should be used wisely. Continuous or
unfounded criticisms will no doubt provoke negative reactions, as will the
same sort of praise. However, in a technical discussion, detailed criticism
can be constructive because it means that the person who is making it has
taken the time to analyse the design or implementation being criticised.
" Avoiding��territoriality: one situation to avoid is where some members of
a community attempt to appropriate part of the project ("their part") and
refuse to accept criticisms or contributions from other members. Although
this attitude may appear positive at first, since these members are usually
experts and spend a great deal of time on their part of the project, the
long-term result is that no other developer revises the code, which can
mean a loss of quality and lead to fragmentation of the community.
(64)
" Automating��tasks: most developers generally work on one part of

the code and do not know what the others are doing. Therefore, the

and which it is often useful to automate and centralise.
The clearest example of this is the automation of tests64, which allows
developers to make changes and experiment with parts of the code that
they are unfamiliar with.
" Treating��users��properly: the existence of an active user community
contributing valuable information to developers is key to the success
of any free software project. However, developers and users often speak
different languages, to put it one way. Many users are not familiar
with software development or how free software communities operate.
Developers need to be able to put themselves in the place of users and try
to explain themselves as clearly as they can.
Just remember that any user could be a contributor to the community and
because the vast majority of users never address the developer community,
we need to reserve special treatment for those who do. For example, when
a user indicates that the documentation is incomplete, we can suggest that
they complete it themselves, or when they report a bug, we can ask them
to try and fix it. And of course, always thank them for their contribution,
whatever it is.
" Sharing��management��tasks: besides code development, every project
has a series of management tasks that become increasingly complex as
the project expands. The coordinators or team that initiated the project
usually take responsibility for them, but it is good to share them with other
GNUFDL " PID_00148382 137 Free software implementation, projects and companies
members of the project, as we saw in the section on delegation. These
tasks include:
 Patch��management. Controlling which patches have been received
and analysing them for acceptance or, as is usually the case, to detect
their problems and report them to the author of the patch.
 Translation��management. Coordinating the translation of the
documentation and software.
 Documentation��management. Keeping the documentation and the
frequently asked questions or FAQs section up to date, introducing
changes as they appear.
 Bug��management. Managing the bug database, which includes
ensuring its integrity and checking for duplicate bugs, among other
functions.
" Permissions��management. One of the more important management
tasks is the management of permissions, i.e. deciding who has permission
to commit and hence, integrate their code into the remote copy in the
repository. Besides granting permissions, there is also the possibility that
we will have to revoke them.
Developers who do not have permission to commit can of course still
contribute to the development of the project by producing patches
to fix bugs or add new functionalities that will be analysed by the
project developers and eventually incorporated. In fact, the most common
mechanism for obtaining permission to commit is for a developer to
contribute patches to the project until the team of developers considers
that his or her contributions and knowledge of the project are valuable
enough.
To encourage the participation of new developers, it is useful to make
the procedure for obtaining permission to commit and the procedure for
withdrawal of this permission public and as transparent as possible.
3.3.5. Releasing and packaging
Preparing releases and packaging is, besides code development, one of the
most important tasks of the entire free software project.
GNUFDL " PID_00148382 138 Free software implementation, projects and companies
A new release involves changes, particularly for users. Firstly, all
known bugs from the previous release will have been solved and
it is highly likely that there will be new ones. There may also be
new functionalities and configuration options. There may even be
incompatibilities between the new version of the software and the
previous ones, in the format of the data, for instance.
Since the jump from one release to the next can have important consequences
 and not all of them good  one of the first aspects we need to decide on is
how to identify each of the releases.
There are several conventions for this, some more creative than others, but
the most common method is to number them with a series of digits separated
by decimal points. For example:
" Release 3.4.1
" Release 3.4.2
" Release 3.5
" Release 4.0
The meaning of these digits can vary. Changes to the third digit usually
indicate fixed bugs or minor improvements to some functionalities. Changes
in the second digit usually indicate the introduction of new functionalities.
And lastly, changes to the first digit indicate new groups of functionalities and
no doubt important changes in version compatibility.
It is a good idea to indicate the meaning of the numbering of the releases on
Website
the project website.
See the versioning of the APR
project ( http://
apr.apache.org/
In addition, some releases are usually identified with the words alpha or beta,
versioning.html ).
indicating their development status. For example:
" Release 3.4.1 (alpha 1)
" Release 3.4.1 (alpha 2)
" Release 3.4.1 (beta)
Generally, the word alpha is used to designate the first release, which allows
users to access the software and all of its functionalities but for which a
considerable number of bugs is expected. Users who install and run an alpha
version usually do so to evaluate the software and report bugs to the team
of developers. A beta version, on the other hand, has undergone far more
debugging and, if it contains almost no bugs, will become the official version:
this is what is known as a candidate version.
GNUFDL " PID_00148382 139 Free software implementation, projects and companies
For developers, a free software project is in a constant releaseprocess and they
always use the latest version available in the repository for development, so it
can be difficult to specify the exact moment of the release.
The best practice in this case is to keep a branch in the repository containing
the code that will be introduced in the next release, regardless of the trunk.
This also ensures that the developers not involved in preparing the release can
continue to work on the project.
Thus, one of the most important parts of the process for preparing a release
is its stabilisation, i.e. deciding which changes and functionalities will be
integrated into the branch of the next release. Here, the decision-making
mechanism of the free software community should come into play, giving us
two basic alternatives:
" Designating a release owner that will decide which changes to introduce
in the future release.
" Voting for the changes to be introduced in the future release, for which
we will need to define the voting rules. An intermediate solution is to
establish the minimum number of developers needed to vote for a certain
change in order for it to be included.
In addition, one or two release managers can be appointed to integrate and
validate the changes to the branch of the release.
Free software is usually distributed as source code, adequately packaged and
compressed in a standard format. The name of the package is usually formed
by the name of the package, the version number and the appropriate suffix
for the format. For example:
" myproject-3.4.1.tar.gz
" myproject-3.4.2.zip
The information that should accompany any new release includes the licence
under which it is distributed, the instructions for installation and set up, and
the changes and features added since the last release. This information is
included in a series of files with more or less standard names: LICENCE or
COPYNG, README or INSTALL, and CHANGES.
(65)
And finally, users need to compile the source code and install it on their

DEB system with GNU/Linux

executables in Windows.
as many users as possible. Another possibility, used especially with mature
software, is the distribution of binary packages, either as executables or
installables, which does away with the need for users to carry out the
compilation process manually65.
GNUFDL " PID_00148382 140 Free software implementation, projects and companies
From the perspective of free software companies, the releases policy is one of
the key tools for reaching potential users of the software. Correct planning
of releases should meet the user needs of the moment, whether by adding
new functionalities or by fixing bugs, so we must determine a suitable rate of
publication for new releases.
For instance, publishing new releases too often can saturate users and they
will probably not install all of the releases. In contrast, leaving too big a gap
between releases could encourage users to look elsewhere for solutions. It is
also a good idea to guarantee the quality of the new releasesby trying to fix as
many bugs as possible before their publication. The effect of a release plagued
by bugs gives a very poor image of the project and the company behind it,
which can be difficult to remedy afterwards. It is therefore very important to
focus on the open and cooperative nature of free software in order to improve
the quality.
3.3.6. Choice of licences
The differences and advantages and disadvantages associated with the various
free software licences make this one of the most hotly debated topics. One
thing is certain though and that is the choice of a particular licence plays a
minor role in the adoption and success of the project as long as it is a free
software licence. The vast majority of users choose their solution based on the
functionality and quality it offers, rather than its licence.
(66)
The most important thing is to be clear on the project aims and the free

under restrictive licences. A typical example is the GPL licence, which requires
any software that uses GPL components to be distributed under a GPL licence.
It is good practice to keep an inventory or chart of the external software and
licences used in the project, describing the parts of the code that use them.
GNUFDL " PID_00148382 141 Free software implementation, projects and companies
Summary
Although free software technology is tested, produced and run in a variety of
scenarios and despite the fact that we can easily find news on products, events
or figures related to free software in the general media, there are still many
clich�s about its real and effective implementation.
These clich�s and misconceptions often have a negative impact on the
implementation of free software systems, both in domestic situations and in
organisations. Users often write off free software saying that it is for computer
experts or hackers or that free software applications are unstable, unfinished
or lack the necessary support. Business, on the other hand, takes the view
that free software does not protect intellectual property sufficiently, that it
represents a loss of competitiveness, or that, with certain exceptions, there are
no feasible business models for free software.
We can summarise most of these ideas as being concerned with a lack of
quality in free software processes and products, particularly in the quality
perceived by users. To a certain extent, however, it is fair to say that the history,
culture and nature of free software and the community of users and developers
have encouraged these ideas.
The growing commitment of governments and major organisations to
free software should encourage people to question these misconceptions.
Moreover, many experts and analysts have pointed out the potential of
free software in bolstering the development of local, European and world
economies. For example, Gartner has said that "OSS is a catalyst that will
restructure the industry, producing higher quality software at a lower cost".
The materials for this subject attempt to provide a response to some of these
clich�s, training professionals to carry out projects implementing free software
systems through the detailed study  from a conceptual, methodological and
practical point of view  of this type of project in a variety of scenarios and
situations.
Generally, any free software project must be treated first and foremost as a
software project and secondly, as an engineering project, so these materials
cannot and should not be a substitute for the necessary knowledge of these
topics.
Most of the materials cover the concepts, methodologies and tools required
to carry out free software development and implementation projects. This
is the reason for the general tone of some of the contents, which gradually
introduce the reader into the methodological features of free software projects,
GNUFDL " PID_00148382 142 Free software implementation, projects and companies
attempting to organise and structure  conceptually and functionally  the
main stages and milestones of implementation. We have also explained
how business activity linked to free software, whether software development,
consulting, integration, implementation or support, can be the object of a
profitable, valid and viable business model. Similarly, and although this was
not the primary aim of the subject, we have introduced the basic aspects that
a business plan should cover, specifically those dealing with free software.
The constant evolution of free software technologies and projects will
no doubt make some of these materials obsolete, particularly those on
specific projects and solutions. However, both the methodology and the
bibliographical references should help us to find the right solution for each
project or implementation scenario.
Moreover, it is hoped that the formalisation and structuring of the
methodologies and procedures included here, together with the collection of
good practices in free software projects will make a qualitative contribution
to the community and to the development and expansion of free software in
general.
Finally, we could not end without thanking the Fundació de la Universitat
Oberta de Catalunya ( http://www.uoc.edu ) for its support in producing these
educational materials. We also encourage all readers who wish to send in
their comments or suggestions to contact the authors so that we can improve
future editions of this material and the everyday practice of implementing
free software systems.

Appendix
Appendix��I:��Free��software��licences
There now follows a short list of the main licences used for the production
of free software. Some of these are discussed in detail in the materials of the
Introduction to free software and Legal aspects and the features of exploitation
of free software (Part II) subjects.
GNU/GPL��v3
GNU/GPL is an abbreviation that stands for the General Public License of the
Internet resource
GNU project.
For more information about
the GNU/GPL licence, see
http://www.gnu.org/licenses/
It has a robust redistribution policy called copyleft, by which all derived works

inherit the original licence, even if they have been combined with others.

Version 3 of GNU/GPL is not directly compatible with version 2. However,
many programs licensed under the second version allow the use of subsequent
versions of the licence under the same terms.
GNU/LGPL��v3
The abbreviation GNU/LGPL stands for the Lesser General Public License of the
Internet resource
GNU project, which is a licence derived from GNU/GPL.
For more information about
the GNU/LGPL licence, see
http://www.gnu.org/licenses/
This licence was originally created to allow the use, linking and integration

of free software libraries with other types of licence, sometimes proprietary,
to work around the restrictions of GNU/GPL licences. The practice has led
to the licensing of numerous programs, some of which are now widespread.
The programs licensed under GNU/LGPL include the OpenOffice.org office
automation package.
Version 3 of GNU/LGPL is not directly compatible with version 2. However,
many programs licensed under the second version allow the use of subsequent
versions of the licence under the same terms.
BSD��licence
GNUFDL " PID_00148382 147 Free software implementation, projects and companies
BSD is the abbreviation of the Berkeley Software Distribution licence of the
Internet resources
University of Berkeley.
For more information about
the BSD licence, see http://
www.debian.org/misc/
It forms part of a group of licences ( BSD-style or BSD-like licences, including

1.1.html.
The abbreviation MPL stands for the Mozilla Public License of the Mozilla
Foundation ).
It is a private initiative that is a hybrid of the BSD and GNU/GPL licences. It is
considered a permissive semi-copyleft licence because it offers the possibility
of establishing proprietary licences from derived works. Linking from modules
with different licences is permitted. Article 13 allows the licensing of one or
more parts of the code with a different licence, called an alternative licence.
Only when the alternative licence is GNU/GPL  or any other compatible
licence  will the part be compatible with GPL and be able to be linked with
others if they are too.
Apache��2.0��licence

works and linking from modules with different licences. The use of patents of
this licence and the provisions for compensation make it compatible only with
version 3 of GNU/GPL, maintaining the incompatibility with the previous
two versions.

CDDL��1.0

License of SUN Microsystems.
For more information about
the CDDL licence, see
http://www.sun.com/cddl.
It is based on version 1.1 of the MPL licence. The main differences revolve
around two aspects:
" The author (or copyright owner) can restrict the legal jurisdiction of the
rights and duties of the software users.
" The licence establishes the requirement of identifying all authors who
contribute to the modifications made to derived works.
It permits linking from modules with other licences and the licensing of
derivatives with a different licence, which can be proprietary. Its intellectual
property features make it incompatible with GNU/GPL.
CPL��1.0

of the original, requiring the payment of any royalties. It is incompatible with
GNU/GPL due to its clauses on the legality of derived works.

focus. The main difference between it and CPL lies in the treatment of patent
infringement by software contributors. All code licensed under EPL maintains
the licence in its derived works. However, it permits the separate licensing
of addenda under other types of licence, including proprietary. Linking from
modules with different licences is permitted. Its characteristics regarding
the permissiveness of derived works and its treatment of copyright make it
incompatible with GNU/GPL.
