I came across Scott Selhorst's material on Use Case Point Estimation. Very useful!
Check out:
- An introduction to use case point estimation with good context for use case newbies
- A How-to for the final calculations
- The free template
The template can also be googled and found at modernAnalyst, another useful source of information for business analysts and such folk.
Note on the large number of use cases: I personally think they are no real use cases. It's quite close to a functional decomposition done in use case form. I expect the system to arrive at about 8000 Function Points, but estimates range from 1.000 to 15.000 as of now :-)
