A Simple Method to Identify Requirement Changes for Improvement in Software Design

The evaluation and performance analysis of software architecture at the design level increases the quality of the software and also reduces the cost of rework during the later stages of the product. There has been a lot of research in the area of software architecture and software design evaluations. When the design is to be improved based on the evaluation results, we lack in a feedback mechanism addressing the issues to be concentrated for design improvement. The paper aims at bringing out inter relationships among the various performance attributes, thereby identifying the specific changes that have to be brought about in design to satisfy customer requirements. The paper addresses a simple methodology using ranking and Karl Pearson method to find the critical areas to be updated for design improvements.
