Enhancement in Function Point Analysis

Early and accurate estimation of software size plays an important role in facilitating effort and costestimation of software systems. One of the commonly used methodologies for software size estimation isFunction Point Analysis (FPA). The purpose of Software size estimation and effort estimation techniques isto provide a useful measure of the software complexities, efforts, and costs involved in softwaredevelopment. Despite almost three decades of research on software estimation, the research community hasyet not able to provide a reliable estimation model for End-User Development (EUD) environments. EUDessentially out-sources development effort to the end user. Hence one element of the size and effort is theadditional design time expended in end-user programming. This paper discusses the concept end-userprogramming and enhancement of FPA by adding end-user programming as an additional General SystemCharacteristic (GSC).
