Abstract
Determinants of performance of systems and processes for planning and decision support are discussed. This paper is directed at people who design such systems and processes, who use such systems and processes, and who manage organizations in which these may be used. The literature cited is associated with several areas including psychology, organizational behavior and design, information science, management science, computer science, and related disciplines. Performance determinants and design requirements for systems and processes for planning and decision support are especially stressed. A number of areas where additional research appears needed are mentioned, and some recommendations and interpretations are given concerning both contemporary efforts and needed future efforts.
