An empirical study of the task dimension of group support system

This study investigates the effects of a GSS on the decision outcome of five-person, face-to-face groups performing two distinct but related task types. A controlled laboratory experiment with a 3/spl times/2 factorial design was employed. The independent variables were support level and task type. A total of 68 groups were randomly assigned to different support levels (no support, structure support, of GSS support). Half of these groups performed an intellectual task while the other half performed a preference task. The empirical findings show that task type affects consensus change and influence equality. Moreover, support level and task type jointly affect decision scheme satisfaction. This paper attempts to reconcile the body of empirical findings from related GSS studies. It discusses the implications of task type for GSS design and use.>
