content: Everything is first-class in this publication, from its title, presentation, unique binding, and organization. In addition to covering the entire subject in a concise way, the E-Book CD multiplies three-fold the resources provided in this volume. Further extention via a licensed web-page seems to justify the claim that this is the most compete Six-Sigma body of knowledge on the market.Salted with checklists, practical tools,diagrams and expert advice, I found myself enjoying the "sail" through the subject.
