Viewpoint Resolution: A Critical Evaluation

Viewpoints-based requirements engineering is an active area of research. This paper provides a critical evaluation of a particular technique for the early validation of requirements using viewpoints. The technique is limited to the syntactic analysis of requirements and lacks a conflict resolution strategy. This paper describes an approach to the very early validation of requirements based on learning about the viewpoints and building models of their behaviour. The method is a collection of domain-independent heuristics to build internal models of the viewpoints that record their performance in providing information, assessing information, and resolving conflicts between viewpoints.
