A good meter for a manager to know if he has too many monkeys is by comparing e-mail inbaskets, since that is where so many of us spend much of our time nowadays. My own is usually over 300 items while my staff's is usually under 20. I thought about each of these as a monkey and then also thought back over all the one-on-one conversations I had had with each of them (7 people). In most cases, it was usually left that I would do something next, and that fits in perfectly with this book. True to the book and the tape, I spend countless hours to catch up, only to fall further behind.
The book is pretty good, but the tape is far superior. There are two tapes; the first one is a speech by Bill Oncken Jr, and he is just a fantastic story-teller. He really brings to life the story of the manager whose staff is all waiting on him, the stress he feels, and the revelation that hits him when he sees them golfing when he goes in on the weekend. Of course this is all written before the days of e-mail, but it still works. You can feel the energy in his voice rising as he turns his life around and puts all the monkeys back where they belong, and the final line where he gets the whole audience to shout "HOW'S IT GOING?!" to the new monkey-owner is a great ending.
The second tape is Ken Blanchard delivering the rest of the material, and while he's entertaining, it's not nearly as good as Oncken's "day-in-the-life" tale. He ties the material back to the One-Minute Manager, and touches on some psychological issues.
They also stress that this isn't just an exercise in delegating and taking work off the manager's hand, it is just as important as a developmental process for the subordinate.
As a side-note, it's interesting that there is no mention anywhere in the book of Spencer Johnson, the co-author of the original book The One Minute Manager, who invented the system. In all the author biographies and Thank-You's, he is never mentioned, I wonder if he and Blanchard had a parting of company. And the book itself makes almost no mention at all about what One-Minute Manager is all about, it seems just a way to put a popular title to a book about monkey management, although I think this monkey manual is the better book.
