"This work will help cement the demand-driven methodology in the mainstream by dramatically strengthening the case for change with clear logic and common sense. Simon has been a huge advocate for the demand-driven movement and this book is a very welcome contribution to the body of knowledge."

Carol Ptak and Chad Smith, co-founders of the Demand Driven Institute

"The circumstances and environments for which the current and universally used forecast push MPS/MRP model was designed are totally different to those of today's highly uncertain world. In this book, Simon Eagle makes a very strong case for the urgent need of migrating to demand-driven models in supply chain management. You will find a comprehensive description of the knowledge frontier in this fundamental area including the basic equations that should drive it, seldom known by people working in the field. Applying these concepts with rigor will give any company a substantial competitive advantage and a clear path for sustainable growth. A must-read for any industry professional in any area, at any level in any industry."

David Poveda, Owner and Director of Flowing Consultoria, Medellin, Colombia

"Thank you to Simon for this in-depth work that contributes significantly to clearly explaining the what, how and why of Demand-Driven MRP. For example, how forecasts should be used to transform supply chain and operations performance. Thank you also for the very interesting appendix on the story behind DDMRP."
