An Algorithm for Evaluating Impact of Requirement Change

Abstract

In software development, it is difficult to evaluate the impact brought by the requirement changes because of the complexities and dependencies among the changed and unchanged requirements. In this paper, the relations of these dependencies are analyzed and established. The scope of the impact caused by requirement changes is identified by a back-tracing algorithm, and impact was quantified. An algorithm developed to quantitatively evaluate the effect of requirement changes is presented. Lastly, the feasibility of this evaluation algorithm is shown through a case-study.
