This book is written for web project managers to-be. I don't believe it will be very useful to experienced project managers. This book is good for people transitioning to web project manager / producer positions. I have several years of marketing management experience and am about to start a web producer position. So this book provided a good basic overview of web project management principles. For a rigorous treatment of navigation, design, info architecture, and other essential topics, I suggest you rely on O'Reilly as so many Amazon web category reviewers have done. I gave this book four stars because it is so thorough (truly a mile wide and an inch deep). But it doesn't get 5 stars because it was so poorly edited. Every chapter includes glaring grammatical mistakes, and in some cases even spelling errors. I question whether the editor (Elizabeth Spainhour) ever read this book!
