Acknowledgments

We would like to acknowledge all the team members we have worked with and learned from in the past. Their work has enabled us to put the concepts in this book into practice. We would also like to thank Myra Strauss, Courtney Chiaparas, and Jill Sulam for transforming our concepts and rough paragraphs into a real book.

Dennis would like to thank Gabe Hoffman, Sherri Turner, and Bryan Thurston for their counsel.

Steve would like to personally acknowledge the Inventory Tracking System team, who came as close to perfecting these concepts as any team could hope to, and Hal Miller, who taught him how science and statistical process control can be applied to the art of software development.

Ralph would like to offer special thanks to Rich Raphael for his enthusiastic and helpful support over many years and to Doug Woods for his suggestions regarding reader feedback.

Finally, we would like to thank our families and friends for encouragement and support.
