FP‐based Estimation
FP based Estimation
• Based on FP metric for the size of a product
p
– Based on the number of inputs (Inp), outputs
(Out), inquiries (Inq), master files (Maf), interfaces
( f)
(Inf)
– Step 1: Classify each component of the product
(Inp Out Inq Maf Inf) as simple average or
(Inp, Out, Inq, Maf, Inf) as simple, average, or
complex (Figure 1)
• Assign the appropriate number of function points
• The sum of function pointers for each component gives UFP
(unadjusted function points)
