3
3. Review the Unadjusted Function Point Count.
4
4. Calculate the Value Adjustment Factor.
5
5. Identify a Calibration Factor.
6
6. Identify a Function Point Delivery Rate (in function points per person-month)
7
7. Identify a conversion factor (person-months to person-days).
8
8. Review the high level estimate of total effort.
