Dear Friends,

I hope you will be able to come up with a valuable suggestions to my query.

Can we use function points to estmate effort of a maintenance project for which we do not have existing function points. Is there anyway to apply this technique without this piece of information. All we have is the source code.

One of the suggested methdodologies we are trying to follow is to reverse calculate the FPA from the source code. The detailed steps are
a. classify all the source code into different technologies.
b. Calculate lines of code for each technology
c. convert LOC into FPA using the conversion factors for that technology.
d. Add these FPA to get the total or add them module wise.

Can you also suggest ways to incorporate code complexity for an object oriented language.

Thanks and regards,
