Presented by Daniel French & Carol Dekkers
Session Description: Roberto Meli developed a more streamlined function point analysis methodology based on the International Function Point User Group (IFPUG) standard function point methodology and released it in Italy in 2010. The Simple Function Point (formerly SiFP, now known as SFP) reduced the number of functions from 5, the 3 transactional functions, External Inputs (EI), External Inquiries (EQ), External Outputs (EO) and 2 data functions Internal Logical Files (ILF) and External Interface Files (EIF) to 2 functions, the Elementary Process (EP) and the Logical File (LF). And rather than having to determine the the type of function and its associated complexity by counting Data Element Types (DET), File Types Referenced (FTR) and Record Element Types (RET) to determine if a function is low, average or high complexity to ascribe a Function Point value, assigns one FP value, 4.6 for an EP and 7 for a LF. This allows for more rapid and cost efficient determination of the function sizing of software with out a significant reduction in accuracy. This presentation will introduce the SFP methodology and highlight the challenges and opportunities for software cost estimators who need to estimate software size from high level software requirements. We will also explore the key differences between SFP and traditional IFPUG FP, including guidance for cost estimators using Function Point measures as the basis for their software cost estimates.
