I like this idea, but I've also seen situations where it's become 1 or 2 holdouts against a chorus of yesses, and then the ensuing resentment against them. And the holdouts had some very good points. I think it can work if the leader/manager is good at this kind of approach, but it can also lead to a lot of conflict as well.
Well, I didn't type this in the original post, but I should clarify: When the question of "tell me what is wrong with this idea" - I specifically make the point of being the one to ask the question.
If you make the discussion directed toward the manager/team leader, then the conversation is much easier.
Again, the team needs to put all their irons in the fire to forge a decision. The plan/ideas of the team is the metal to be forged. The fire is the funding and backing for the project. The hammer is the effort of the executing team and the tongs are the skill of the overall project management.
