2. Abstract
Open Source Software (OSS) is software products
available to the public, with its source code to study,
change, and improves its design.
However when open source used for commercial purpose,
then an open source license is required.
The quality assurance principle under open source
software development is an approach to improve software
product quality against traditional (or) new methods and
techniques.
Many industries and business sectors are following or
using OSSD

4. Introduction
Open source is a model of software development that has
been growing since the 1970's.
Exactly like the personal computer and the Internet, open
source software recently got the attention of the press as a
totally new thing that ‘suddenly appeared’.
Open source software is becoming the most interesting
‘new’ phenomenon of the entire information technology
landscape, generating a level of interest similar to that of
the First moments of the Internet.
Open source software extended this idea by using the
Internet to recruit a much larger population of volunteer
developers.

5. Open Source Software
Open-source software (OSS) is software which can be
used, modified and improved by anyone and can be
redistributed freely.

6. OSS free from
The freedom to study and modify the
software.
The freedom to copy the software.
The freedom to improve the software.

7. Open Source Business Models
Traditional New
Support Sellers Service Enabler
Loss Leaders Brand Licensing
Software Franchising
Widget Frosting
Sell it, Free it
Accessorizing

8. Traditional: support sellers
Companies that package together open Source
software, and make their money from either selling a
software and changing to service the software
 Red Hat is the leader in this industry

9. Traditional: Loss Leaders
Company that generally gives away software for free
and makes money from selling additional software
Example:
 Adobe
 Fedora

10. Traditional: Widget Frosting
Company that sells hardware and packages it
together with open source software
Silicon Graphics: Supports and shapes Samba
VA Linux

11. Traditional: Accessorizing
Company that sells books, compatible
hardware, t-shirts, bumper stickers, coffee
mugs, dolls, etc.
Example: O’Reilly sells more of the compatible
hardware, manuals, software

12. New: Service Enabler
Company that distributes open source software
primarily for generating revenue through on-line
services
 i.e. On-line gaming

13. New: Brand Licensing
Company that charges other companies for the right
to use its brand names and trademarks in creating
derivative products

14. New: Software Franchising
A combination of several of the other models in
which a company authorizes others to use its brand
names and trademarks in creating associated
organizations doing custom software development
and supplies franchises with training and related
services in exchange for franchise fees of some sort

15. New: Sell it, Free it
Software products start out their product life cycle as
traditional commercial products and are converted to
open source products when appropriate

16. List of Open Source Software:
Firefox
Feed Reader
Open Office
Thunderbird

17.  Advantage of OSS  Disvantage of OSS
 Learning curve
 Stability  Equivalent programs
 Free Software  More technical ability
 Runs on old hardware needed
 Security  Not all hardware
compatible

18. The current practical picture for
OSS deployment
 Browser
 Desktop OS
 Email
 Content Management System
 Digital library services
 Integrated groupware
 Library catalogues
 Network services
 Office suite
 Payroll
 Scientific workstation
 Student records
 VLE & portal

19. Conclusion
Free/open source software systems for government
represent a significant opportunity
Seek high-level, user-friendly processes for
government operations expressed as open source,
computationally enact able processes
