Take for instance the "project charter" which is widely known as the formal initiation document for a project. Kerzner says the charter has time and cost, resource assignment and other information which logically doesn't even get created until much later in the process! Many, many examples of other illogical statements throughout the book which make it very tough to digest! Good book as a general all round reference... just don't take it as the bible of project management. Many PM's ignore about 70% of what he suggests.
I have used Kerzner as a textual job reference since the 4th Ed. As a fairly experienced PM, the text is an excellent desk reference. A wonderful well rounded text.
However as an instructor, it quickly became clear to me that students without a broader business background need a lot of handholding to understand the assumptions that cross functional mid and upper level managers take for granted. It is good at giving you the skeleton, but you have to know how to attach the flesh yourself. It gives you things to think about but you still have to weed the good from the bad and make decisions on your own. After all, PM isn't about doing things one way. This book will not do your job for you or teach you how to do your job, but it can help you do a better job.
I still believe this is an excellent text, but not for those "green" to the field or for PMP review.
And yes, the cartoons are stupid...
