Testimonials
“At times early in the project, I felt you should be up in front of the room leading the discussions and the overall project. As I look back, I now agree 100% with your approach. You ultimately did the right thing because it ultimately made Moen lead this initiative.
You have an amazing way of “telling the story.” When you speak, people listen and you show very strong leadership. I dread the day that you leave Moen, but I think we will be in good shape – largely due to all of your hard work and mentoring. Thank you!”
~ Jeff Fox, IT Manager, Supply Chain and Quality Systems
“Wonderful read! The Only All-in-One Way to Fix Your Supply Chain should be required reading for all supply chain leaders that have an ERP system. This book has done an excellent job of laying out the transformational “must-knows” that most companies fail to recognize. They often chase fancy bolt-on solutions or additional software applications.”
“David does an excellent job of discussing what is possible using standard ERP functionality, moving away from environments that have significant “offline” or “manual” planning processes. David outlines the importance of executive leadership support and how each layer of management is expected to contribute to the transformation.
“Not only do I think this book is an excellent read, but I experienced what David outlines within the book. I was a supply chain leader who worked firsthand with David, using this methodology to transform a global supply chain. This process broke down silos within the supply chain organization and created efficiencies throughout our organization, especially shop floor efficiency and performance. We realized significant improvements in our enterprise Customer Delivery scores while also reducing inventory holdings by 40%, while utilizing standard SAP processes & transactions. It was not easy, but well worth the effort as the processes have consistently served as the foundation for that supply chain.
“Give this book a read and if your supply chain is in chaos, it will help you to understand how to regain control and transform your supply chain.”
~Brian Koester, Manager, Materials & Production Planning, Moen
