To compute function points (FP), the following relationship is used:
FP = Count_total × (0.65 + 0.01 × ΣFi)
where Fi (i = 1 to n) are value adjustment factors (VAF) based on n questions. The value of n is:
- A.
12
- B.
14
- C.
16
- D.
18
Attempted by 218 students.
Show answer & explanation
Correct answer: B
Answer: 14 The value adjustment factors (VAF) are based on 14 general system characteristics in the standard Function Point (IFPUG) method.
Therefore n = 14 and the formula should be interpreted as:
FP = Count_total × (0.65 + 0.01 × Σ(Fi) ), where i runs from 1 to 14
The 14 general system characteristics (the basis for the 14 VAFs) are:
Data communications
Distributed functions
Performance
Heavily used configuration
Transaction rate
On-line data entry
End-user efficiency
On-line update
Complex processing
Reusability
Installation ease
Operational ease
Multiple sites
Facilitate change
This list explains why there are exactly 14 VAFs in the formula, so n = 14.
