Book excerpt: Unlike other pocket guides, this guide is designed specifically to address topics that the author has found to cause problems, issues, and concerns for most Black Belts over the years. As such, its primary purpose is to serve as a useful reference guide for the Black Belt throughout his or her busy day, and particularly in meetings. Though not intended to be a tool guide like other pocket guides or a preparation guide for the ASQ certifications, it will nonetheless serve as a useful reference guide for both the ASQ Black Belt and Master Black Belt certification examinations. Black belts will enjoy reading this pocket guide and find it invaluable in their daily work.
