I think there is a problem, in some corners of the Air Force, that everyone has become so busy supporting the bureaucracy that the proper time can't be given to brainstorming sessions and idea development. Guys are treading water in the office while min-running mission knowledge. The only active idea soliciting going on is the "anybody got anything for me" part of the weekly CC call. Guys may have good ideas or bad ones, but they'll never be asked in the first place. Fixing tactical problems is priority #22 in a lot of places.
Leading an open, honest, and non-retributional "bitches/gripes/complaints" session once every couple of weeks might help open things up a bit.
