The open source initiative and its followers propose
a software development model that promotes free
distribution and complete access to source code [1] [2].
This model has been labeled “the open source
development”, “the open source model”, or just plainly
“open source”. Its origins can be traced back to the
“hacker culture” that created UNIX, Linux and part of
Internet infrastructure [2][3]. However, recent success
stories of many products developed under this model
has given enormous momentum and visibility, making
it an interesting alternative for large software
development companies [4].
