Software Reuse

There has been tons and tons of books/articles on software re-use...But even then we still end my writing the software from scared when we can get similar modules (if not same) for much less effort and cost.

Reusing software would mean, you decide what are the key functionalities required, and what good to have can be compromised.

Best places to look for software reuse is your organization software factory or the open source software components. Open source not only provides with the basic key functionalities that brings up the whole software development on much faster grounds.

Also remember that if you can get an off the shelf software or component, which meets 90% of your requirement, then its worthy to buy it and ignore the other 10% of the requirement. Yes ofcourse it depends upon how critical the other 10% is!
