Abstract

Software Change Effort Estimation (SCEE) is required not only in software maintenance phase, but it is also required in software development phase. Many methods have been developed to estimate effort for software requirement changes. Function Point Analysis (FPA) is one of these methods, which is used to estimate effort for software requirement changes during software maintenance phase. In software maintenance phase software artifacts are in consistent state. One main challenge for this method from software development perspective is that the presence of inconsistent states of software artifacts, i.e. some classes are completely developed, some of them are partially developed and some are not developed at all. Hence, this research proposes a new SCEE model that overcomes this challenge using the combination of Change Impact Analysis technique (CIA) together with Function Point Analysis (FPA) method. The results of our new model, i.e. Function Point Analysis for Software Development Phase (FPA-SDP) can help software project managers in terms of: (1) predicting the impact of change requests on software artifacts and (2) understanding the actual conditions of inconsistent states of software artifacts during software development phase.
