Agreed. I actually think consensus amongst the team is more important than your boss. If a group of reports under some manager come to consensus on something they need to do, the opinion of the boss is kind of moot. I tend to operate using a bias for action, and the boss is clued in with information about our decision making, but asking for permission (or forgiveness) really just opens the door for micromanagement. This assumes basic trust has been established between the team and the manager, but in the end the technical decisions should be chosen by those on the team who are technical (read: not management).

Management (in my opinion at least) is primarily for resource allocation, career growth, and shielding the team from endless meetings and acting as a point of contact for upper management
