What are the steps to estimating using function points?
Is there a quick-reference guide of some sort out there?
I took a conference session on Function Point Analysis a few years back. There is a lot too it. You can check out the Free Function Point Training Manual online, the Fundamentals of Function Points, or I suspect you can get a book on it at a computer store.
You might also check out the International Function Point Users Group and see if they have some resources or a local meeting for you.
