Abstract
-
A large literature exists concerning the implementation and use of computer decision aids such as management information systems and decision support systems. However, a very limited literature is available about what factors lead to the perception of usefulness and satisfaction with the latest form of computer decision aids--expert systems.;This research describes, explains and proposes a new theory of interaction between competing computer decision aids and individuals. A model is presented that shows how individual characteristics moderate the user's satisfaction and the user's perception of the usefulness of the information generated by alternative computer decision aids. The experimental study is exploratory in nature. The research design required the participants to evaluate both type of systems over an eight week period.;A major finding of this exploratory study is that the user's cognitive style plays a critical role in determining how an individual responds to either an expert system or a decision support system. Individuals whose cognitive style is classified as Feeling-oriented and Intuitive-oriented express greater satisfaction and perceive greater usefulness of information when using an expert system while those classified as Sensing-oriented and Sensing/Thinking oriented express greater satisfaction and perceive greater usefulness of information when using a decision support system. The findings also indicate that those individuals who are "experts" for a particular decision domain, express less satisfaction with an expert system than with a decision support system. Individual's tolerance for ambiguity or locus of control had no relationship to his/her satisfaction or perception of usefulness of information for either the expert system or the decision support system.
