...but the fundamental tenets of brainstorming - "no criticism" and "maximize quantity" - are anathema to implementation. "After the initial idea" there is a limited solution set governing "how to do it" or else you failed your due diligence in the first place. "Let's figure out how to tell Janice we're taking the christmas party planning away from her" does not have nearly as many possible solutions as "let's pick a theme for the Christmas party" and the solutions to the first problem have consequences, while the solutions to the second do not. Thus my point - brainstorming works best when it really doesn't fucking matter what the answer is. As I tend not to worry about problems whose solutions are irrelevant and hold a dim view of those who do, I've yet to encounter a brainstorming session that was worth the time.
