This research examines three major factors that influence idea creativity in an electronic brainstorming session: GSS tools used in brainstorming, task/technology fit, and perception of idea creativity as group performance. Based on previous research, we found that 1) GSS tools can generate higher number of high-quality ideas than traditional idea generation by reducing production blocking and expanding discussion; 2) The use of creativity software led to significantly more creative ideas and thus improved creativity performance; 3) Establishing norms of behavior regarding communication task-technology use would enhance the performance of global virtual teams, and a good fit between media functionalities of technologies and specific tasks would enable virtual teams to achieve greater levels of effectiveness; 4) Quality of discussion, task completion, process satisfaction, outcome satisfaction, idea quality (originality and feasibility), and creativity were most commonly used as a measurement of group performance in previous GSS research.
