Jerry Wishes says: "In this book I provide fifty-four improvement tools. They are focused around two concepts. First, Variation is Evil. Every process has variation but the secret is to restrict it to natural causes and then use improvement tools to 'manage' the variation. Second, use of the tools is not optional. Once you embrace them, you do so forever." He goes on to say: "Embrace the tools, practice them until they become a part of your life, then move on the concept of discipline and a Team Centered Organization. Finally, you will be ready to understand and adopt the principles of perfection."
