Process knowledge based rapid prototyping for requirements engineering

Rapid prototyping offers an iterative approach to requirements engineering to alleviate problems such as uncertainty, ambiguity, and inconsistency inherent in the process. As the systems development process is characterized by changing requirements and assumptions, involving multiple stakeholders with often differing viewpoints, it will be beneficial to capture in a structured manner the history of the development process. The authors describe how CAPS (computer aided prototyping system) as a prototyping tool, augmented with REMAP (representation and maintenance of process knowledge) framework for reasoning with process knowledge, helps firm up software requirements. This is accomplished by iterative negotiations between various customers and by examination of executable prototypes in the context of evolving requirements.<
