Lean Thinking (NL)

In 1990, Womack and Jones described in *The Machine That Changed the World* what set Toyota apart from other automakers. That book laid out the facts. *Lean Thinking*, published in 1996, answered the question everyone was asking afterward: how?

The answer provided by Womack and Jones consists of five interrelated principles that together offer a comprehensive alternative to mass-production thinking. This has since become the foundation of the global Lean movement. This book launched that movement.

What do you learn in Lean Thinking?

Lean Thinking is divided into four parts that together provide a comprehensive overview of what Lean is, how it works, and how you can apply it in your own organization.

Part 1 lays the groundwork: the five core principles of Lean— customer value, value stream, flow, pull, and perfection. These five concepts remain the starting point for any serious Lean training and implementation. Womack and Jones also introduce the three crucial management tasks of every organization and the criteria for evaluating Lean processes, moving beyond the traditional definition of efficiency.

Part 2 shows how Lean works outside of Toyota and the automotive industry. Using a variety of companies as examples, the authors demonstrate that the five principles are universally applicable in manufacturing, service industries, and everything in between.

Part 3 focuses on the practical aspects of a Lean transformation: how do you implement it in your own organization, from the first steps to strategic integration?

Part 4, added in the second edition, contains the authors’ reflections after years of Lean adoption worldwide: what worked, what proved more difficult than expected, and what remains to be gained.

Why should I read *Lean Thinking*?

Lean Thinking is the book that brought the term “Lean” to the world outside Toyota and defined what it meant. Nearly thirty years later, it remains a surprisingly powerful foundational text—not because it is historical, but because it lays the groundwork that other books take for granted.

Anyone already familiar with Lean through training, tools, or workbooks will discover in *Lean Thinking* the original context and depth behind concepts that now seem like common sense. That insight not only makes you a better practitioner, but also a better conversation partner—someone who understands why Lean is what it is, and not just how it works.

The book has been published in Dutch by the Lean Management Institute and is therefore accessible to a wide Dutch audience.

Who is *Lean Thinking* intended for?

• Anyone who wants to get serious about Lean and understand the thinking behind the tools
• Managers and executives who are considering a Lean transformation and want to know what it entails from a strategic perspective
• Lean practitioners who want to learn about and explore the origins of the five principles
• Teams looking for a common foundation and a shared language for their improvement efforts

What do fellow writers think of this book?

"Lean Thinking gave the world a language for something Toyota had been doing for decades. Without this book, the Lean movement would have looked very different—if it had existed at all." — Jeffrey K. Liker, author of The Toyota Way

"This is the book I give to every executive who asks me what Lean really is. It’s not a workbook, not a manual, but a way of thinking that sticks with you." — Michael Ballé, author of The Gold Mine and The Lean Manager

About the authors

Jim Womack is co-founder of the Lean Enterprise Institute and one of the most influential Lean thinkers in the world. Together with Daniel Jones and Daniel Roos, he conducted the groundbreaking MIT research that led to *The Machine That Changed the World*; the book that introduced the term “lean production.” Lean Thinking was the logical next step: moving from describing the facts to formulating the principles. Since then, Womack has spent decades guiding organizations worldwide through Lean transformations and is regarded as one of the architects of the global Lean movement.

Daniel Jones is a co-founder of the Lean Enterprise Institute and the Cardiff Business School Lean Enterprise Research Centre. As co-author of both *The Machine That Changed the World* and *Lean Thinking*, he has made a decisive contribution to translating the Toyota Production System into a broadly applicable management philosophy. Jones has been particularly active in applying Lean in the British healthcare, retail, and service sectors, and later co-authored *Handbook of Lean Solutions* with Womack, also available in the Lean Management Institute’s webshop.
