ABSTRACT: It is a mistake to categorize decision support systems (DSS) as just another recent variant of traditional computer-based information systems. While traditional computer-based information systems are oriented toward performing structured processing tasks and producing regular reports, DSS have the purpose of supporting nonroutine activities and evolving in response to user learning. Thus a different subset of factors should be considered when developing a decision support system. This paper proposes and defines a conceptual model of DSS development whose origins are based on an open systems approach and whose components capture technical, behavioral, and organizational aspects of the development process.
