Requirements change management on feature-oriented requirements tracing

Abstract

User requirements have been changed during development progresses, since they are impossible to define all of software requirements. These requirements change leads to mistakes because the developers cannot completely understand the software structure and behavior, or they cannot discover all parts affected by a change. Therefore, requirement changes have to be managed and assessed to ensure that they are feasible, make economic sense, and contribute to the business needs of the customer organization. We propose requirements change management process on feature-oriented requirements tracing. It is based on value analysis and feature-oriented requirement traceability links. Our approach offers two contributions to the study of requirements change: (1)We define a requirements change tree model to make user requirements change request generalize by feature level. (2)We provide overall process such as change request normalization, change impact analysis, change request alternative design, change request implementation, and change request evaluation. In addition, we especially summarize the results of a case study which is carried out in asset management portal system. © Springer-Verlag Berlin Heidelberg 2007.
