Question

Explain the steps of function points?

Answer 1

The steps of function points are:

First Count ILF, EQ, EI, EIF, FTR, DET, RET and use the rating tables. After counting all the elements you will obtain the unadjusted function points.
 Put rating values 0 to 5 to all 14 GSC. Adding up, the entire totals 14 GSC to come out with total VAF.

Formula for VAF = 0.65 + (sum of all GSC factor/100).

Lastly, calculate the adjusted function point.

Formula: - Total function point = VAF * Unadjusted function point.
Calculate how many function points you will do per day. This is also known as "Performance factor". On basis of this, you can calculate Man/Days.
