Compute and prepare function point value for a project with the following information domain
characteristics. No. of external inputs-30 No. of external outputs – 52 No. of external inquiries-22 No. of
logical files-12 No. of external interface files-2 Assume complexity adjustment values for the above are
average (4, 5, and 4,10,7 respectively). The system requires significant reliability(4), is moderate
performance critical(2), system requires moderate online data entry(2) and all other factors are incidental.
Is this Correct? if yes then what is the use of reliability, performance critical and data entry values.
(EI): 30 × 4 = 120, (EO): 52 × 5 = 260, (EQ): 22 × 4 = 88, (ILF): 12 × 10 = 12,0 (EIF): 2 × 7 = 14
UFP = EI + EO + EQ + ILF + EIF = 120 + 260 + 88 + 120 + 14 = 602
CAF = 0.65 + (0.01 × UFP) = 0.65 + (0.01 × 602) = 0.65 + 6.02 = 1.07
FP = UFP × CAF = 602 × 1.07 = 643.14 (approximately)
