Collaborative requirements engineering: an overview and a proposed integrated model

This paper includes an overview of requirements engineering models, which have largely been created to support the early phase of the information systems development (ISD) process. The review shows that it is unclear how the information obtained can be effectively utilized during the later stages of the ISD process. Furthermore, most of the existing models are "generic" and are not linked with any specific ISD method. This paper takes the position that integrating requirements engineering models with a specific ISD method will improve the performance of systems analysts in the design deliberation process and construction of analysis models. A model based on this position is proposed.
