"Every week, the teams have two meetings. One in which to brainstorm, to forget about constraints and think freely....to "go crazy". Then they also hold a production meeting, an entirely separate but equally regular meeting which is the other's antithesis. Here, the designers and engineers are required to nail everything down, to work out how this crazy idea might actually work." It seems like a great idea to separate brainstorming and refining into two meetings. From my experience, doing them in the same meeting is hard. You don't know when to cross over from free thinking to critical thinking. Tension arises when some folks end up drilling down into one idea while others are still brainstorming new ones at a very high level.
