This book is truly built on the shoulders of many giants, from the original work of the practitioners who developed MRP, including Joe Orlicky, George Plossl, Richard (Dick) Ling, and Ollie Wight, to the great thinkers behind lean, Six Sigma, and Theory of Constraints—Taiichi Ohno, W. Edwards Deming, and Eliyahu Goldratt. The authors have stood on the shoulders of these giants to unite these different theories and methodologies and take a leap forward—into a future of planning with relevant visibility that mitigates the volatile, uncertain, and variable world that seems impossible to plan. We have known many of these giants personally and wish to express our continued appreciation to them.
Collectively, the authors would like to thank the members of the Demand Driven Institute Global Affiliate Network for a great partnership in bringing demand driven concepts to the mainstream throughout the world.
Additionally, the authors would like to thank various members of the APICS community for their amazing input and support in trying to restore the promise of effectiveness planning and information systems. Those people include Keith Launchbury, Roberta McPhail, John Melbye, Ken Titmuss, Olivia Reary, and Abe Eshkenazi.
The authors would like to point out particular individuals who have made a lasting contribution to the demand driven body of knowledge and awareness. These people include Greg Cass, Debra Smith, Erik Bush, David Poveda, Dick Ling, Paddy Ramaiyengar, Kirk Black, Caroline Mondon, Alfonso Navarro, Dr. Patrick Rigoni, Dr. Steven Melnyk, Christoph Lenhartz, Laurent Vigouroux, Dr. Romain Miclo, and Alfredo Angrisani.
Chad Smith would like to thank his wife, Sarah, and two daughters, Sophia and Lily, for putting up with the process of writing books and courseware. The support and love of these three people has kept him going. Chad would like to thank the team at Constraints Management Group, LLC, for an amazing journey for nearly 20 years. Specifically, Chad would like to acknowledge the inspiration and accomplishments of his mother, Debra Smith; her direction-setting vision has been instrumental in articulating the Demand Driven Adaptive Enterprise model. Finally, Chad would like to thank his partner and coauthor Carol Ptak for an extremely rewarding and fulfilling partnership.
Carol Ptak would like to thank her husband, Jim, for the understanding and the continued support to keep going through the tough times. Words are so insufficient to acknowledge her parents, Dorothy and Bud, who taught her from the youngest age that she was limited only by her imagination even at a time when the glass ceiling was more like concrete. Their love and encouragement has been the wind under her wings. Carol would especially like to thank Chad Smith for an incredible experience and continued partnership—far beyond any that could ever have been imagined. Chad has opened all our eyes to the deeper truth of a new world of planning. The process of writing three books together has been an incredible journey and truly has been an honor and the highlight of a very long career.
“It is not the most intellectual of the species that survives; it is not the strongest that survives; but the species that survives is the one that is able best to adapt and adjust to the changing environment in which it finds itself”.
The above quote is often falsely attributed to Charles Darwin. While undoubtedly inspired by Darwin’s work, it was Leon Megginson, Professor Emeritus at Louisiana State University, who is the source of this quote. Megginson wrote several books on small business management, published over 100 articles, and won numerous awards for teaching and research.1 Regardless of the source of the quote, the message for business leadership should be powerful: adapt or die.
The dodo bird is an extinct flightless bird that was native to the island of Mauritius, first recorded by Dutch sailors in 1598. When the Dutch colonized the island, they brought with them dogs and pigs. This resulted in an immediate and profound change to the dodo’s native environment, one to which it could simply not adapt. The last credible sighting of a dodo was in 1662. In less than 100 years the dodo was gone. It disappeared so quickly many thought it was a mythical creature until researchers in the middle of the nineteenth century thoroughly studied remains of the bird.2
What can be learned from the dodo? The dodo had no say on the changes to the environment; they were imposed upon it. In today’s world of volatility, uncertainty, complexity, and ambiguity (VUCA) there is a high degree of probability that organizations will have environmental changes imposed
