"Weinberg's original Secrets of Consulting has a place on every consultant's (at least the ones that are making any money) bookshelf. If you have not read Jerry's original book, you will be surprised at how he makes simple analogies and symbols so meaningful. And how these analogies, rules and symbols lead to a better personal performance from the consultant. This time around he gives us the "consultant's tool kit" of symbols. He devotes a chapter to each of these symbolic tools, from The Wisdom Box to The Fish-Eye Lens to The Oxygen Mask. Jerry Weinberg's career is the envy of most consultants that I know. I find it wonderful that he is prepared to share the secrets of his success.

"Buy this book if you are a consultant, or thinking of becoming one."
