Value Adjustment Factors

Introduction This chapter introduces General System Characteristics (GSCs) and the Value Adjustment Factor (VAF). The function point counter should keep in mind that neither the GSCs nor the VAF are included in the IFPUG Functional Size Measurement (FSM) Method, and they are considered optional in the IFPUG Function Point Counting Practices Manual, Release 4.3. This chapter, however, includes definitions and examples of each GSC as well as the formulas used in computing the VAF and an adjusted functional size (aFP).
