We’ve all been in brainstorm sessions that went nowhere. At IDEO.org, the goal isn’t a perfect idea, it’s lots of ideas, collaboration, and openness to wild solutions. The last thing you want in a brainstorm is someone who, instead of coming up with ideas, only talks about why the ones already mentioned won’t work. Not only does that kill creativity, but it shifts the group’s mindset from a generative one to a critical one. The only way to get to good ideas is to have lots to choose from.
