In the global marketplace, no business is a self-contained island. No matter how effective your internal material movement, to be a future-thinking business, you must go to the next step and develop long-term supplier partnerships built on a dedication to continuous improvement and the basic concepts of Lean implementation.

Lean Supplier Development: Establishing Partnerships and True Costs Throughout the Supply Chain provides step-by-step instruction on how to build partnerships of mutual improvement and success through supplier development. Offering the same advice that they have successfully applied to corporations across the globe, award-winning consultants Chris Harris, Rick Harris, and Chuck Streeter —

  • Provide criteria on how to choose suppliers that will make good long-term partnerships
  • Demonstrate proven methods for employing Plan for Every Part (PFEP) to link your facility to the supply base
  • Present a true cost model that eliminates guesswork when choosing suppliers to develop
  • Show how to develop and maintain efficient information flow all along your supply chain
  • Use real-world examples to cover likely contingencies
  • Provide a sample quarterly supplier review that you can adapt for your own use

Lean is a journey, not a destination. It requires flexible leaders at the helm who can readily adjust to ever-changing conditions and it requires like-minded partners all along the supply chain. Finding and developing these partners is not about good fortune, it is all about an uncompromising approach to continuous improvement and the application of systematic methods that will build working partnerships that broaden your definition of what is possible


Most companies struggle to move beyond the four walls of their business during a lean journey. Many lean leaders have never ventured to the great world of the unknown related to the supplier, but for lean to reach continued breakthrough levels of performance, lean supplier development is required to extend throughout the entire supply chain. Conversations around supply chain lean activity abounds in the consulting world, but few people can bring real life success stories, experience and processes to the picture as Rick Harris, Dr Chris Harris and Chuck Streeter. Their personal, hands on experience is evident once again in this book, their latest venture in true kaizen. They have the unique ability to shoot straight at the target and never talk over the head of the audience. The reader is able to understand the thinking process and then begin implementation starting with the opening lines of the book. This book is not just thoughts, but a detailed process of why, how and when to begin and implement lean supplier development. If your company accelerated improvement with Rick’s red book and shot life into it with the green book, this book will take performance of the total supply chain to an all new level. Let Rick, Chris and Chuck help you enjoy, not fear, the journey!

—Mark Gooch, VP Lean Enterprise, Pentair, Inc.

Rick and Chris Harris' practical knowledge from so much work in the field helping businesses with lean transformations shines through in this piece of work. The book can be viewed as a checklist adaptable to any business striving to develop an effective supply chain. Be careful not to miss the real gems they offer in the simple and sometimes subtle warnings of traditional behaviors that could impede future success.

— Kathryn A. Miller, Vice President, Lean Enterprise & Quality, Parker Hannifin

For most manufacturing based businesses direct material costs account for 40-60% of COGs. It is therefore absolutely IMPERATIVE that your supply base become LEAN practitioners if your company is to fully capture the strategic and operational benefits of becoming a truly LEAN Enterprise. Rick and Chris Harris provide a roadmap to accomplishing that goal. Read it, understand it, adopt the principles yourself, convert your supply base and watch your top line revenues and bottom line profits grow!
