Much has been written about the management of change, and it usually focuses on the challenges, acknowledging just how difficult change really is.
When you turn it around, and consider what happens in successful change programs, there is very little management, and a lot of selling.
Leaders lead from the front, demonstrating the behaviors necessary, whilst managers push from behind. Demonstration is the oldest, and still the best form of selling, so when those whose work place, and the processes they operate are subject to being changed seeing those with the decision making power demonstrating the altered behavior makes the change easier.
You do not manage change, you sell it.
You sell it to your employees, shareholders, customers, suppliers, and anyone else who will stand still long enough to listen, and most importantly, believe.
