Sharpen the focus
Start with a well-honed statement of the problem at hand. Edgy is better than fuzzy. The best topic statements focus outward on a specific customer need or service enhancement rather than inward on some organizational goal
Write playful rules
Ideo’s primary brainstorming rules are simple: “Defer judgment” and “One conversation at a time.” The firm believes in its rules so strongly that they’re stenciled in 8-inch letters on conference-room walls. “If I’m the facilitator and somebody starts a critique or people start talking, I can enforce the rules without making it feel personal,” Kelley says. Other rules include, “Go for quantity,” “Be visual,” and “Encourage wild ideas.”
Number your ideas
“This rule seems counterintuitive — the opposite of creativity,” Kelley says. “But numbered lists create goals to motivate participants. You can say, ‘Let’s try to get to 100 ideas.’ Also, lists provide a reference point if you want to jump back and forth between ideas.”
Build and jump
Most brainstorming sessions follow a power curve: They start out slowly, build to a crescendo, and then start to plateau. The best facilitators nurture the conversation in its early stages, step out of the way as the ideas start to flow, and then jump in again when energy starts to peter out.
“We go for two things in a brainstorm: fluency and flexibility,” Kelley says. “Fluency is a very rapid flow of ideas, so there’s never more than a moment of silence. Flexibility is approaching the same idea from different viewpoints.”
Make the space remember
Good facilitators should also write ideas down on an accessible surface. Ideo used to hold its brainstorms in rooms wallpapered with whiteboards or butcher paper. Lately, however, the group has started using easel-sized Post-it notes. “When the facilitator tries to pull together all the ideas after the session,” Kelley says, “she can stack up nice, tidy rectangular things instead of spreading butcher paper all the way down the hall.”
Stretch your mental muscles
Brainstorming, like marathon running, should begin with warm-up exercises. Ideo studied various methods of prepping for a session. For a project on the toy industry, for example, Ideo divided the group into three teams: The first team did no preparation. The second listened to a lecture on the technology involved and read background books. The third team took a field trip to a toy store. Far and away, the toy-store team produced ideas in greater quantity and quality than the other two.
Get physical
At Ideo, brainstorming sessions are often occasions for show-and-tell. Participants bring examples of competitors’ products, objects that relate to the problem, or elegant solutions from other fields as springboards for ideas. Ideo also keeps materials on hand — blocks, foam core, tubing — to build crude models of a concept
