These stats aren’t just grim,
they’re embarrassing.

“David has the unique ability to share this management vision with his customers while at the same time providing the building blocks and skills operational teams need to achieve success.  Combining David’s leadership with the Reveal oVo methodology makes for an unstoppable force!”

~John Bassi, Former Reveal oVo Integration Advisor S&OP Center of Excellence – Bio-Rad Laboratories

“For me what I learnt from you was how you taught planning folk how to align the system with the business, setting all the data correctly, deciding exactly what products were MTO/MTS etc, flowing through from SD, MM to PP and WMS managing by exception to correct the system daily in cross functional teams, that is special and unique and a gift to supply chain planners everywhere – use the force Luke!”

~David Christian, Global Business Transformation Leader

“David is a remarkable leader with a unique ability to engage deeply with complex challenges and translate them into practical, value-driven business solutions across the supply chain. His expertise goes beyond strategic discussions; he possesses the rare skill of translating high-level insights into actionable solutions within the SAP system. This enables companies to fully leverage their SAP investment, driving sustainable business outcomes and creating long-term value.”

~Christy Stokrp, Senior Director @ W. R. Grace & Co. | Global Supply Chain Transformational Leader

“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

“I was fortunate to have the ability to work with David directly for a couple of years with the primary focus on optimizing our production planning and inventory management practices. David is certainly an expert in his field and understands how to utilize SAP to its fullest extent to optimize a business’s supply chain and inventory investment while also driving world class customer service levels. When he refers to Reveal methodology as an “unstoppable force” he is absolutely spot on”.

~Ian Eckman, Vice President of Integrated Supply Chain – GAF Commercial

“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

“I’ve had the pleasure of working with David Carroll as he guided us through a transformation of our use of SAP in our complex operations and supply chain, each with unique challenges. His expertise in SAP, and the Reveal Methodology, brought structure and efficiency to our processes, enabling us to use standard SAP, and achieve significant cost savings. The Reveal Methodology truly is an unstoppable force, driving tangible results by uncovering inefficiencies and optimizing workflows to achieve organizational targets. His insights and hands-on approach not only improved our systems but also empowered our teams with new skills and tools that served us long-term. I can confidently say his impact on our supply chain has been profound, measurable, and sustainable.”

~Andy Tylke, Supply Chain Manager, Project Manager, Loparex

“David is a proven and experienced supply chain professional.  His focus on customer and organizational goals and as well as measurable outcomes was evident on a daily basis.  He is a pleasure to work with as well and assimilates well into all teams he worked with.  Also, I found David’s deep supply chain and SAP knowledge highly beneficial as we sought to optimize planning, sourcing and production execution processes.   5-stars all around!”

~ Mike Livermore, Director, U.S. Operations Systems, Retired

“I have not had much time to read. Halfway through 4 definitely the details (weeds). I keep finding parallels to our company.

Our management team should read before S4 Hana , but their egos would get in the way.”

~ Anonymous, Senior Business Analyst

“I’ve finished the book. I loved it. So much truth. Thanks for sharing with me.”
