Requirements Analysis through Viewpoints Oriented Requirements Model (VORD)

Abstract

This paper describes an extension to the Viewpoints Oriented Requirements Definition (VORD) model and attempts to resolve its lack of direct support for viewpoint interaction. Supporting the viewpoint interaction provides a useful tool for analyzing requirements changes and automating systems. It can also be used to indicate when multiple requirements are specified as a single requirement. The extension is demonstrated with the bank auto-teller system that was part of the original VORD proposal.
