Like The Dilbert Principle, this book is not a mere collection of Dilbert cartoons, although it includes a number. Instead, it’s a text derivative of the world inhabited by Dilbert, Dogbert, Catbert, Ratbert, Alice, Tina, Wally, Pointy-Haired Boss, Asok, and so on. This book takes the schtick of being a handbook for managers from Dogbert, the evil genius. Within, you find that it explicitly tells the executives reading how to behave as a Dilbert executive should.
Sadly, although the book is 12 years old, the behavior seems timeless. Fortunately, that means the humor is fresh, and you can laugh cynically. Or you can take it to heart and thrive as an executive.
