Design for Lean Six Sigmais the only book that employs a "road-map" approach to DFSS, which allows corporate management to understand where they are in the process and to integrate DFSS methodology more fully into their overall business strategy. This is a similar approach to that used by Forrest Breyfogle in his successful book: "Implementing Six Sigma, 2E". This approach will allow corporate management to understand where they are in the process and to integrate DFSS methodology more fully into the overall business strategy. Another important aspect of this book is its coverage of DFSS implementation in a broad range of industries including service and manufacturing, plus the use of actual cases throughout.

"This book provides the historical context of Lean and Six Sigma then delivers on the evolution to holistic DFLSS (Design for Lean Six Sigma) - what it is, why, and how and when to apply it. DFLSS are covered in the context of designing and developing processes, products, services, and systems. The technical examples and strategies provide conceptual depth and definition, helping the reader appreciate the complexity and rigor that can be brought to bear for competitive innovation."
