Creationstorming is a method conjured up by Teague Labs that contrasts with open Brainstorming. Its is a mechanism by which teams can quickly come up with ideas around very specific topic area. The key word here is QUICK!
One of the things I like about Creationstorming are the rules:
1. There are bad ideas.
It’s okay to disagree with an idea. Encourage critical debate: challenge others, defend yourself. Wild ideas are welcome, but be prepared to back them up.
2. One idea to rule them all.
Keep the focus on building one solid idea that progresses. Ideas can fork and merge, but don’t lose sight of the goal for the session.
3. Time is short. Think fast, talk faster.
Sessions should be kept as short as possible, so be on your toes and be concise. Interrupt long-winded digressions to keep things on track.
Martin Thaler, my officemate and Associate Professor at ID, calls it 'focused brainstorms', suggesting that free for all brainstorms sometimes lead nowhere!
