A labolatory experiment examined the effects of applying decision support system (DSS) technology to decision making in ill-structured problem environments under varying information conditions. Marketing executives participated in the experiment which investigated the effects of DSS availability, DSS training, and data availability on dependent variables that included (1) the number of alternatives considered by a subject during decision making, (2) the period of time spent by a subject to complete the decision-making process, (3) the subject's perceived confidence in the decisions he or she had made, (4) the amount of data considered by a subject during decision making, (5) the individual subject's decision processing, and (6) the subject's performance overall. Our results indicate that all three factors significantly affect the number of alternatives considered by subjects during the decisionmaking process. We therefore suggest that DSS training be coordinated with decision training in order to realize the potential of DSSs as described in the DSS literature.Subject Amas: Decision Support Systems and Management Information System.
Information technology has made possible the recognition, acquisition, organization, and controlled retention of data from sources virtually unavailable in the past. Terms such as “the information society” and “information glut” have become commonplace. High‐level corporate positions with titles such as Chief Information Officer are being created in an attempt to efficiently and effectively use information for the benefit of the organization and the society it serves. A major challenge in the 1980s is to gain and maintain the ability to use this information for competitive advantage. Decision Support Systems (DSS) enable marketing managers to integrate internal and external information environments within a decision‐making context. Useful features available within Marketing Information Systems can be incorporated with the potentials of DSS. Together the two systems can provide marketing managers with opportunities to anticipate, identify, and creatively respond to changing consumer demand.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
