Function Point Cost Model 3
Function Point Cost Model or Analysis (FPC) Developed by Alan Albrecht Of IBM 1979. FPC is a method used to measure various cost in a software application. FPC measure the functionality from the user point of view FPC is based on User Input and the Output expected by system FPC is a simple tool takes parameters to calculate the over all software cost 4
Why FPA ? GSU: Software Engineering - CSC4350/6350 - Rao Casturi 5
Steps involved in FPC Method Identify system boundary Boundary defines the functions included in the FPC 6 SYSTEM (Internal Logic / Files) (ILF) Users U s e r s External Files and other systems (External Interface Files) (EIF) Input Output Inquires to the system (External Inquiry)
FPC Weighting Factor Estimate (UFP) 7 EI EO EQ ILF EIF Unadjusted Function Point Calculation Table UFP
