Decision support systems are interactive information systems which incorporate both data and modeling capabilities in an effort to support and improve human decision making. The goal of a decision support system is to support the entire decision making process. In order to do this, an understanding of each phase of the decision making process is necessary. This study focuses on the choice phase of decision making in order to provide useful information to more comprehensive decision support systems. Specifically, the effects of embedding choice strategies into the design of decision aids on decision maker performance and perceptions were examined. Three decision aids were used in a laboratory experiment for a consumer selection task. The first imposed a compensatory choice strategy, another imposed a noncompensatory strategy, and the third allowed the decision maker flexibility to use one or both of those strategies. / The experiment resulted in the following findings. First, performance effectiveness was highest with the noncompensatory decision aid, however, the evaluation method had a tendency to bias those results. This finding indicates that several evaluation methods are necessary for a complete understanding of effectiveness. As for efficiency, both imposed strategy decision aids were more efficient than the flexible aid. For this particular task, a structured approach is preferred for both effectiveness and efficiency. Finally, the perceptions were not significantly different for subjects using any of the three decision aids. This finding is particularly useful so that the most appropriate strategy can be employed without fear of negative impressions which could lead to lack of system use. / Source: Dissertation Abstracts International, Volume: 53-03, Section: A, page: 0880. / Major Professor: Thomas D.
