I did, having built up a large, multi skilled workforce, delivering what we perceived was excellent Customer Service. Then along came someone who had attended one of Tom Peters' seminars & immediatley identified that I was the epitome of what Mr P was advising them to avoid. He bought me a copy of this book and I read it, I laughed, I cried (when I thought just how smug and conceited I had become) and then I planned to change, and change we did.
Using just a few of the ideas but a lot of the thoughts, it is very simple to identify areas which you think you are good at, but really that is only from your own internal view point and not you customers.
If you manage people, BUY THIS and read it, if you manage managers BUY THEM IT too - it will be the best investment you will have made !!
