Toyota is often cited as the inspiration for Lean, but its success is rooted in leadership behaviors, management systems, and a deep commitment to learning—not tools or slogans. This archive brings together blog posts, podcasts, and reflections on Toyota’s approach to quality, continuous improvement, psychological safety, and respect for people. Many of these posts explore what leaders outside Toyota often misunderstand—and what truly matters if they hope to learn from Toyota rather than copy it.
Somebody says it in the comments of nearly every post about Lean, usually with a few exclamation points. “Toyota doesn’t call it Lean!” It gets offered as if it settles the matter. I’ve said a version of it myself. Talking…
I’ve been reading The Birth of Lean, a collection of talks and interviews with the people who helped build the Toyota Production System. One passage stood out because it explains something I had never seen described this clearly: Toyota copied…
When I was a young engineer at GM’s Livonia Engine Plant in the mid-1990s, I wrote down some of the things production workers said to me. One of them stuck, a worker in a machining department: “I want to stop…
For years, I’ve been asking a very specific question about Lean history: Where was Toyota’s first andon cord? Jeff Liker didn’t know. Neither did Isao Yoshino. I’ve asked other former Toyota people. Toyota histories and books about the development of…
Most Lean programs treat standardized work and kaizen as opposites. Standardized work is the rigid part. Kaizen is the creative part. One constrains, the other improves. Pick whichever side you prefer and argue with the other camp at the next…
Twenty years ago this month, I recorded the first episode of Lean Blog Interviews. My guest was Norman Bodek, who spent decades studying Toyota and introducing American audiences to the work of people, including Taiichi Ohno and Shigeo Shingo. I’m…
The 1992 Toyota booklet says surprisingly little about leadership. There’s a Kiichiro Toyoda quote about engineers getting their hands dirty. There’s a brief sentence about executives visiting the workplace and acting on what they see. That’s about it. For a…
It came across my LinkedIn feed again last week, and then a day later, a friend sent me the same thing from Instagram. Same story, a few words moved around, or copied word-for-word. If you spend any time in Lean…
I was reading The Birth of Lean, the Lean Enterprise Institute’s collection of interviews with the people who built the Toyota Production System, and one answer from Eiji Toyoda is worth quoting in full. This is Eiji Toyoda on mistakes,…
LinkedIn has a genre of infographic that’s very popular right now… that’s mostly right. You’ve perhaps seen them. A clean illustration of a Toyota assembly line, a worker reaching up for a cord, and a caption along the lines of:…
Nearly two million improvement proposals in a single year. Ninety-seven percent implemented. That doesn’t sound like the suggestion-box model most organizations know. It sounds like something else. The number comes from Toyota’s April 1992 publication “The Toyota Production System.” It…
102 seconds versus 300 seconds. That’s the comparison the 1992 booklet uses to make the case for one-piece flow. Three employees on an assembly line. Three processing steps. Same work, same number of people, same total processing time. The only…
