I have never seen brainstorming sessions be useful, and they've been heavily in vogue since I was in pre-school.

Nobody ever actually prepares for them, so they don't have the slightest idea what the real constraints of the situation are. So huge amounts of time are wasted getting on the same page, then more as somebody bolts off on an impossible tangent that upsets the whole applecart. No one ever takes any notes, and every participant comes away with a different understanding of what was decided.

A singularly useless endeavor.
