Abstract
The concept of Decision Support Systems (DSS) has been the focus of much discussion among information systems academicians and practitioners in recent years. One trend has been the increasing recognition of the term “DSS” as embodying not just a set of tools or technologies, but rather, signifying a change in the methodologies required in the semi-structured problem-solving domain. An important issue for DSS development is DSS requirements analysis, and several formalizations and methods have been proposed in various DSS design methodologies. This paper describes a method for performing DSS requirements analysis that is based on a model of user enquiries. This model may be used for a more focused investigation of user requirements, with the derived user enquiries subsequently translated into DSS specifications. It compares the method with those used by existing DSS methodologies, and illustrates its use via a case study involving the development and use of a Marketing DSS (MKDSS). The benefits of this enquiry-based approach are identified, and the intended contribution toward DSS methodology described.
