NESMA Impacted Enhancement Function Points

The Netherlands Software Metrics Association (NESMA) has published guidelines on counting enhancement projects that supplement the IFPUG guidelines. Full details of the NESMA Method can be found in FUNCTION POINT ANALYSIS FOR SOFTWARE ENHANCEMENT GUIDELINES Version 2.2.1. The NESMA Method considers the application of FPA to software enhancement from the perspective of the standard function point analysis method. The result of this work, embodied in these guidelines, is a method applicable to software enhancement and testing that is strongly related to the standard FPA method. The term Enhancement Function Point Analysis (EFPA) is used to differentiate the method from the standard function point analysis method.
