Depending on how many you have in your staff and your organization structure your methods work very well. I spent 20 years in the military and actually in my first assignment and my last assignment, the work was scheduled very much like what you describe. The assignments in between were another story and were a disaster.

I managed over 300 people (directly or indirectly) in my last assignment. When I showed up at that assignment, my commander described the methodology you discuss and said IMPLEMENT IT. They sent me to some management seminars and we all executed it "yes sir". I had meetings with my senior staff and then if a crisis popped up, we would have a round table.

Meetings never lasted more than 1 hour, and one learned the meaning of delegation. It's nice to see people are using something I learned in the military over 15 years ago. I can't seem to get it over to my civilian counterparts in companies where I consult.
