Creative Thinking: What Is the Right Size for a Brainstorming Group?

In brainstorming, the right size of group is critical to maximize creativity and generate new ideas. The ideal number usually ranges from two to three on the low side to eight to ten on the high side. A group of two to three works best when participants are diverse and adept at multiple strategic thinking perspectives. A larger group might have too many people listening to one person and would require managing through smaller groups. Ultimately, a balanced creative thinking session allows for individual contributions while maximizing other people's idea-sharing opportunities.
