Very interesting article explaining why brainstorming doesn't work so well, and suggesting another approach, the equally buzzwordish 'brainswarming':
While the traditional brainstorming has always involved a room full of collaborators blurting out ideas, McCaffrey proposes a more silent approach called “brainswarming,” which encourages individual ideation within the context of a larger objective. You start brainswarming by placing a goal or problem at the top of a white board, then listing the resources available to meet these problems at the bottom. Members of your team sit independently and write down ideas for tackling the problem from either end.
McCaffrey has found that natural “top-down” thinkers will begin refining the goal, while “bottom-up” thinkers will either add more resources or analyze how resources can be used to solve problems. The magic happens in the middle, where these two factions connect.
One for the workshop toolbox.
