Developing Lean Leaders at all Levels: A Practical Guide is a management Must Read. The Lean Leadership Development Model (LLDM) presented in this book is intuitive and aligns well with accepted principles of operational excellence. It expands significantly on the elements of Lean, structuring them in a more specific way that can be operationalized by lean practitioners. You can learn everything you want about the Toyota Way; you can implement the tools they have created, but if you do not have the behaviors established within your culture, it will not be successful for long-term sustainment of operational excellence. Leadership must walk the talk of true north in every aspect of this model. George created the online course to help organizations close the knowledge and experiential gap using the book and online course.
