Review chapters and case descriptions suggest that expert systems and decision support systems are useful decision aids in human resource management. Our study examines this belief by exploring the effects of two such systems on the quality of employees' desired benefit choices and satisfaction with benefits in a flexible benefits environment. Results show that employees' current benefit choices and desired benefit changes are related to satisfaction with benefits. Those using both computerized decision aids signaled benefit choice intentions that more closely corresponded to expert system recommendations than those not using a decision aid, but those using the expert system desired to make more expert-like decisions than those using the decision support system. In addition, those using the expert system had greater satisfaction with benefits than those not using a decision aid and those using the decision support system. These results suggest that expert systems have potential for improving decision making and influencing employees' attitudes for human resource problems.
