Idea generation software can be useful in electronic brainstorming and creativity tasks. Based on the theory of task/technology fit, we discuss two software features: graphic/outline mode and communication support, and propose that these features can improve group’s creative performance in an electronic brainstorming task. We assess group’s creative performance by idea creativity, which in turn can affect group members’ satisfaction with the outcome of the electronic brainstorming session, and satisfaction with the electronic brainstorming process. We develop a theoretical framework to explain these relationships and state propositions associated with the research model. Practitioners can use the model to improve an electronic brainstorming session and researchers can extend our framework by exploring in depth the software interactive mode and communication support of idea generation software, and the interaction of both features.
