A model for requirements change management: implementation of CMMI Level 2 specific practice

Abstract

OBJECTIVE – The objective of this research is to implement CMMI Level 2 specific practice – SP 1.3-1 manage requirements changes. In this paper we have proposed a model for requirements change management and also discussed initial validation of this model. This model is based on both an empirical study that we have carried out and our extensive literature review of software process improvement (SPI) and requirements engineering (RE). METHOD – For data collection we have interviewed SPI experts from reputed organisations. Further work includes analysing research articles, published experience reports and case studies. The initial evaluation of the model was performed via an expert review process. RESULTS – Our model is based on five core elements identified from literature and interviews: request, validate, implement, verify and update. Within each of these elements we have identified specific activities that need to take place during requirements change management process. CONCLUSIONS – The initial evaluation of the model shows that the requirements change management model is clear, easy to use and can effectively manage the requirements change process. However, more case studies are needed to evaluate this model in order to further evaluate its effectiveness in the domain of RE process.
