Process Knowledge Based Rapid Prototyping for Requirements Engineering

Abstract

Rapid prototyping offers an iterative approach to requirements engineering to alleviate the problems such as uncertainty, ambiguity, and inconsistency inherent in the process. Further, 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. In this paper, we describe how CAPS (Computer Aided Prototyping System) as a prolotyping tool, augmented with REMAP (Representation and Maintenance of Process Knowledge) framework for reasoning with process knowledge captured during requirement engineering, helps firm up software requirements through iterative negotiations between various customers and designers via examination of executable prototypes in the context of evolving requirements.
