An expert modeling support system for modeling an object system to specify its information requirements

This paper presents an anlyst support system that partially automates the process of determining information requirements. The focus of this paper is upon the problems associated in developing a clear and consistent understanding of the object system by the analysis team, where the object system is essentially the larger system that an information system serves. It describes the design of a computer aided tool which is based upon an extension of SADT and it incorporates the use of problem domain knowledge-base and decision concepts of Simon. The emphasis is on the rationale for the structure and components of this tool and how it may be used for modeling the object system and performing both component and precedence analysis. The problem of generating information system requirements is reduced to traversing the conceptual model.
