Many people believe that decentralization means loss of control. That's simply not true. You can improve control if you look at control as the control of events and not people. Then, the more people you have controlling events - the more people you have that care about controlling the events, the more people you have proactively working to create favorable events - the more control you have within the organization, by definition.
Pride is the fuel of human accomplishment.
I'm not wild about accepting responsibility without authority. Why should my people be?
