The Back Story – Critique of Lean

This is the back story to the book Critique of Lean.CofLCover Small

Lean is a product. Products are designed. Designs have weaknesses. Critique of Lean examines weaknesses in the product and its design.

In the nearly 30 years since the term “Lean” was introduced, we have a just handful of examples of (Real) Lean transformation. Unfortunately, there are many more examples of Fake Lean and Lean transformation process failures than there are successes – by a wide margin. What accounts for the huge gap between expected and actual outcomes?

I have closely followed the evolution of Lean and its application in industry. As a long-time practitioner, contributor to the body of Lean knowledge, teacher, coach, and careful observer, I have watched people needlessly struggle because of widespread misinformation and misunderstanding about Lean in relation to its association with Toyota’s management practices.

This association began in 1988 with the initial characterization of Lean as synonymous with the Toyota production system (TPS). Post-2008, Lean was characterized as synonymous with Toyota’s management system (TMS). But, was Lean ever actually synonymous with TPS? No. Is Lean synonymous with TMS? No.

The differences between Lean and TPS and TMS are vast, and recognition of this has been dreadfully slow and remarkably incomplete by the people who gave us Lean: James P. Womack and Daniel T. Jones. The organizations that they founded and continue to lead, the Lean Enterprise Institute in the U.S. and Lean Enterprise Academy in the U.K., have dutifully carried forward the myths that Lean = TPS and Lean = TMS for 20 years.

The result is that people have labored under illusions of sameness with TPS/TMS, only to discover that the results they achieve are far less than they anticipated. In addition, people have been harmed by Lean though layoffs and other types of unfavorable outcomes, due in part to mindsets, principles, and practices that are enshrined in TPS/TMS but which have long been missing in Lean.

Critique of Lean explores the many factors that account for the large gap between expected and actual outcomes. In doing this, it exposes the myth that Lean = TPS and Lean = TMS.

This volume utilizes the method of scholarly criticism to illuminate weaknesses in the Lean construct and identify pathways for improving Lean. It gives both the originators of Lean and its practitioners two improvement options: Improve Lean quickly to reduce the gap between TPS/TMS, or abandon Lean and pursue TPS/TMS – both with the intention to achieve better outcomes for all stakeholders.

It is time to stop pretending that Lean is the same as TPS and The Toyota Way. And it is time to move beyond the hype and mindless cheerleading. Learn what is wrong with Lean and improve it. Critique of Lean will show you the way.
