Open Source Software - Definition
“OSS is licensed software in which the source code is made available to
users to enable them to modify it for their own purposes and
(within certain restrictions) redistribute original and derived works
as they see fit.”



No one has exclusive control over the term “open source”
Not an enforceable copyrighted term or trademark
Open Source Initiative (OSI) www.opensource.org – was
founded in 1998 & has unofficial power over the core concepts

Open Source Software – Definition
Free redistribution
“License shall not require a royalty or other fee for such sale”
Source code
Must include source code & allow distribution (or a wellpublicized means of obtaining the source code)
Derived works
Must allow modifications & allow them to be distributed
Integrity of author’s source License must permit distribution of software built from modified
code
source code
No discrimination against
Persons, groups or fields of endeavor (e.g. genetic research)
Distribution of license
Rights to program must apply to all without the need for
execution of additional license
License must not be
specific to a product
The rights attached to a program must not depend on the
program’s being part of a particular software distribution
License must not restrict
other software
Must not insist all other programs distributed on the same
medium must be open-source software
License must be
technology-neutral
No provision of the license may be predicated on any individual
technology or style of interface

Open Source Software – History
 GNU Project
 Mass collaboration project of software developers
 Founding Goal: “I will develop a sufficient body of free
software so that I will be able to get along without any
software that is not free”
 First project was to replicate the Unix operating
system
 Recursive acronym meaning “Gnu’s Not Unix”

Open Source Software – History
 The word “free” in “free software” pertains to freedom,
not price
 Think of “free” as in “free speech,” not as in “free beer”

Open Source Software – History
 Linux
 By 1990, the GNU Project had created all of the major
O/S components except for the kernel
 Linus Torvalds, from Finland, decided to develop a
free Unix/Minix-based operating system

Open Source Software – History
Hello everybody out there using minix I'm doing a (free) operating system (just a hobby, won't be
big and professional like gnu) for 386(486) AT clones.
This has been brewing since april, and is starting to get
ready. I'd like any feedback on things people like/dislike in
minix, as my OS resembles it somewhat (same physical
layout of the file-system (due to practical reasons) among
other things).
I've currently ported bash(1.08) and gcc(1.40), and things
seem to work. This implies that I'll get something practical
within a few months, and I'd like to know what features
most people would want. Any suggestions are welcome, but
I won't promise I'll implement them :-)

Risks / Challenges Faced
Panera
• Maintaining a stable environment amidst many changes and
rapid growth
• Security – what is embedded in source code? (Panera uses 3
anti-virus engines that secure us from this issue)
Scottrade
•Difficulty getting managerial buy-in
•“If it’s free, it can’t be good”
•No technical support
•Compatibility issues
AmDocs
•Less robust features than commercial software
• No guarantee of quality or fitness
• Considering system functional compatibilities, some proprietary
software should be used.

Total Cost of Ownership
 Open Source
 Free Redistribution
 Support is fee-based and at a fraction of proprietary systems
 Training – depends on ease of use
 Proprietary
 Pay for license (high up front fees)
 Phasing out free tech support & less manuals with product (support is
close to becoming similar to open source)
 Training – depends on ease of use

55
Total Cost of Ownership
How much does “free” software really cost?
1. Price of software is relatively low compared to TCO (total cost of
ownership) 2
2. The significant costs =
Staffing needed (for any platform of software)
Training, maintenance, support, administrative
50-70% of a software system’s TCO over it’s useful life 2
3. Analyzing TCO is not simple – it depends on the different ways people
use the software. 1

Total Cost of Ownership
How much does “free” software really cost?
Summation:
Open source software key advantage is not always low cost of ownership
1
• Administrative and support costs overshadow initial software license
cost and annual maintenance fees (costs that are minimized by open
source) 2
• Whether open source software is less costly to administer than
proprietary software depends on a ready pool of resources trained
on the system 1
• Situation varies from application to application

Lessons Learned & Best Practices
Due to the current global down economy, we have seen interest in open
source software spike among mainstream and conservative enterprises
alike in recent months. 1
 Over 10 years of Gartner studying open source software dynamics, there are
many examples where enterprises successfully leveraged open source for
significant cost savings over closed source.
 Gartner also found where adopters were unable to clearly demonstrate
sustained cost savings over time.
 Key Factors to optimizing software costs:
– Focus on project maturity
– Understand that project governance dictates both quality and risk (IP concerns)
– Identify specific technology risk profile 1
Understand early in the process which alternatives are more viable:
 Number of users organizations –
 Peculiarity of Operating System Platform
 Product Market Maturity
 Sourcing Attitude
 Available Skills

61
Lessons Learned & Best Practices
 Involvement, positioning and decision-making levels of management affect the
success of migration projects
 While migration to open source offers cost savings in the long run, deploying the
new technology may involve considerable expenses
 Cost reduction is an important motive for organizations to migrate from proprietary
to open source software
 Well timed and sustainable training contributes to the success of migration project
 Developing a clear process for migration and involving a qualified project team
contributes to the success of migration project
 The migration from old to new technology requires shifting the mindsets of users
towards the new technology
 Support available from multiple vendors reduces the risk associated with vendor
lock-in
 Business-IT partnerships are required to facilitate the implementation of new
technology
 Migration from proprietary to open source software involves overcoming internal
resistance to deploy new technology within an organization
