Advantages

The availability of the source code and the

right to modify

The right to redistribute modifications and

improvements to the code

The right to use the software in any way

No ``black boxes'' are possible.

Companies profit

A number of companies have been built around a so-

called open source business model, where they license their software for

free or very inexpensively, but derive their revenues from support and

training services.

Many enterprise users of IT have been winners

because the open sourcing of commodity software such as application

servers, web server software, development tools, and other middleware

has driven down the price of middleware in general.

CONCLUSION:

Open source software development is

relevant to investment research because it reduces the

research and development expense of the publicly

traded companies that make use of it. Much use of

open source involves burying a component or software

artefact deep into an otherwise closed-source software

product or service
