A Model for Viewpoint Control in Requirements Elicitation

Abstract

Requirements elicitation from multiple human sources involves uncertainty management. Most requirements analysis methods focus on expressing the requirements and ignore the uncertainty inherent in the process of requirements elicitation. This paper proposed a model for requirements elicitation from multiple viewpoints. The model is based on the idea of building internal models of the viewpoints that record their performance in providing information, assessing information, and resolving conflicts between viewpoints. The paper argues that the proposed approach provides a better mechanism in information validation and conflicts resolution. The paper is part of the work reported by the author in Messaoudi (1994).
