Like a magician reveals his tricks, it's high time to demystify the often-overrated role of big consultancies providing you with services in the field of restructuring, productivity and efficiency. You know full well that, at the end of the day, you are the one who does most of the consultants' work. You don't need the expensive "white collar" advice given to your management board.
What you really need is stimulation for that vital "click" in your head! Something to help you accept the change process in a slightly different way. Some out-of-the-box oversight throughout the change management process never goes amiss. And being given the freedom by your management board to make a few mistakes while changing things is important too. Then just add a small dash of the charisma required to engage a critical mass of people around you, and you are now ready to become a real leader for change. You are the chief change officer and your people will rally around you. They will follow through on your change.
Just remember one thing - once you read the book, change management will not become any easier in itself. You'll just become much better at being able to SCORE your change and WIN.
