Development of Software Size Estimation Application using Function Point Analysis (FPA) Approach with Rapid Application Development (RAD)

Abstract

Software size estimation has an important role on software development life cycle (SDLC) for helping developers to focus on their target and give a control on development process. Estimation needs a method that give high accuracy with minimum result errors that developers can use it as an approach to the real software size they built. Function Point Analysis (FPA) is one of many methods that can estimate the software size. FPA estimate the software size on Function Point that can be used to count the software line of code (LOC). The research aim is to build a software to estimate a software size using FPA method. Rapid Application Development (RAD) is used to develop the software and needs four iteration to complete the development. On 4^th iteration, the Black Box Testing method has been used to evaluate the program, using 13 datas of a software that have been completely developed. The result is, mean relative error on the estimation result for the proposed program is 3,52%.
