• Assign a value from 0 (“not present”) to 5 (“strong influence
throughout”) to each of 14 factors such as transaction rates,
portability (Figure 2)
portability (Figure 2)
• Add the 14 numbers: This gives the total degree of influence
(DI)
– TCF = 0.65 + 0.01 × DI
– The technical complexity factor (TCF) lies between 0.65 and 1.35
– Step 3 The number of function points (FP) is then
Step 3.The number of function points (FP) is then
given by
• FP = UFP × TCF
