Module 3: Software Design & Metrics

20267m

A project has 30 external inputs, 60 external outputs, 23 external inquiries, 8 files and 2 external interfaces. The corresponding complexity weights are 4, 5, 4, 10 and 7. Four of the fourteen value-adjustment factors have value 0, four have value 3 and the remaining six have value 4. Calculate the Function Point value.

Function Point Calculation

Formula: FP = UFP x VAF

  • UFP (Unadjusted Function Points) = sum of (count x weight) for the five components
  • VAF (Value Adjustment Factor) = 0.65 + 0.01 x (sum of the 14 factor ratings)

Step 1: Unadjusted Function Points

Component Count Weight Count x Weight
External Inputs (EI) 30 4 120
External Outputs (EO) 60 5 300
External Inquiries (EQ) 23 4 92
Internal Logical Files (ILF) 8 10 80
External Interface Files (EIF) 2 7 14
UFP 606

Step 2: Value Adjustment Factor

The 14 factors (rated 0 to 5):

  • 4 factors with value 0: 4 x 0 = 0
  • 4 factors with value 3: 4 x 3 = 12
  • 6 factors with value 4: 6 x 4 = 24

Sum of ratings (ΣFi) = 0 + 12 + 24 = 36

VAF = 0.65 + 0.01 x 36 = 0.65 + 0.36 = 1.01

Step 3: Function Points

FP = UFP x VAF = 606 x 1.01 = 612.06

Answer

Function Point value = 612.06 (about 612 FP)

Since VAF is slightly above 1, the system is a little more complex than average, so the adjusted size is a little higher than the unadjusted count.
