| Summary: | 碩士 === 國立中正大學 === 資訊管理學系 === 91 === Group Support Systems（GSS）are computer-based software that allows people in different places to discuss and make decisions on connected computers. The use of GSS is said to be able to overcome a few major drawbacks of the traditional face-to-face meeting, such as groupthink and blocking effects. The system allows participant to discuss anonymously. The computer network also allows more people to present their ideas simultaneously. Given these potential benefits, plenty of previous studies have been conducted to investigate whether using GSS can increases meeting productivity or satisfaction to the participants. Unfortunately, the results, as shown in the many published articles, have been inconclusive in many aspects.
A major problem is the lack of a full understanding of the group decision making process. To eliminate the gap, the study conducts a laboratory experiment to examine the role of collective efficacy in GSS meetings. Collective efficacy is the ability that group members believe the can cooperate to complete a task. The results indicate that GSS collective efficacy has a significant positive effect on GSS performance. Furthermore, prior GSS performance significantly affects GSS collective efficacy, outcome expectation, and GSS performance. Implications from those findings are also provided.
