Effects of Experience-based Work Patterns in a GSS Environment

Existing group support system (GSS) research has focused on the impacts of GSSs on conventional group-work patterns. Few studies have examined the effects of different group-work patterns in a GSS environment. Specifically, we are interested in group-work patterns that vary in terms of group members' experience or ability levels. In this paper, we report on an exploratory experiment designed to compare the effects of three distinct experience-based work patterns on group decision quality, efficiency, and participant satisfaction in the case of GSS usage. There is the conventional work pattern in which persons of differing experience levels work simultaneously in a meeting. An alternative pattern consists of experienced participants working on a problem first and then passing their results on to less experienced participants. Yet another pattern reverses this sequence. Our results show that while groups in the conventional work pattern are more efficient in considering alternative solutions, groups organized in the other two experience-based work patterns can produce higher quality solutions. We observed no significant differences in participant satisfaction among the three group-work patterns. These findings suggest that a GSS can be as effective (or even more effective) with alternative group-work patterns as it is with the conventional pattern.
