Effective Brainstorming

This chapter reviews the extensive literature on brainstorming to determine potential best practices. It presents the major theoretical perspectives and highlights their relationship to the various factors that influence the effectiveness of brainstorming. It examines the utility of verbal brainstorming, electronic brainstorming, and brainwriting for generation of creative ideas. It evaluates the effects of instructions, breaks, facilitators, training, tapping semantic categories, turnover, and group size. It also notes the gaps that exist in the literature and future research directions. It is clear that there is now considerable evidence to guide effective brainstorming and produce performances in groups that exceed those of comparable sets of solitary brainstormers.
