The Need to Critical Review of Function Point Analysis

Abstract

This Critical Review aims to evaluate the Function Point Analysis (FPA) methodology to be more reliable. It also evaluates the calculation process to be more efficient, effective, and repeatable. This study modifies the function point by adding the complexity of business processes in General System Characteristic (GSC). This is because some studies criticized GSC since it was difficult to be repeated and subjective. Therefore, it is strongly recommended to modify the GSC so that the FPA get more attention on this area. GSC calibration should be done by modifying the Complexity of Business Processes (CBP) because of the change of CBP might result a more complex needs in software development. In addition, organizational business processes are different from each other, as well as their complexity. Finally, the CBP affected the size of the software developed. Therefore, this research proposes a modification of the function point by modifying/adding the CBP to the 14 General Characteristic System (GSC) factors that are expected to improve accuracy to be more objective and reliable. This modification is expected to provide a variety of different software sizes but it more accurate. This research could answer the differences in the point function test results that have the same size.
