Consider a software project with the following information domain characteristic for calculation of function point metric.
Number of external inputs (I) = 30 Number of external output (O) = 60 Number of external inquiries (E) = 23 Number of files (F) = 08 Number of external interfaces (N) = 02
It is given that the complexity weighting factors for I, O, E, F and N are 4, 5, 4, 10 and 7, respectively. It is also given that, out of fourteen value adjustment factors that influence the development effort, four factors are not applicable, each of he other four factors have value 3, and each of the remaining factors have value 4. The computed value of function point metric is ____________
(A) 612.06
(B) 212.05
(C) 305.09
(D) 806.9
Answer: (A)
Explanation: Function point metrics provide a standardized method for measuring the various functions of a software application
The value of function point metric = UPF * VAF
Here,
UPF: Unadjusted Function Point (UFP) count
VAF: Value Adjustment Factor
UPF = 4*30 + 60*5 + 23*4 + 8*10 + 7*2 = 606
VAF = (TDI * 0.01) + 0.65
Here TDI is Total Degree of Influence
TDI = 3*4 + 0*4 + 4*6 = 36
VAF = (TDI * 0.01) + 0.65
= 36*0.01 + 0.65
= 0.36 + 0.65
= 1.01
FP = UPF * VAF
= 1.01 * 606
= 612.06 Refer https://cs.uwaterloo.ca/~apidduck/CS846/Seminars/abbas.pdf
