Lean Thinking: ingredients, incubation and diffusion | John Shook | Planet Lean

“What does it really mean to say that lean thinking is not uniquely Japanese? First, it indicates that not all Japanese companies are ‘lean.’ […] Secondly, we have successful examples of lean applications all around the world – not just in Japan […]. We know these things to be true.
To say, however, that lean is not uniquely Japanese doesn’t mean that there is nothing Japanese about it. So, let’s explore this second, little explored, idea. […] by asking more questions. One critical question we can ask ourselves is: “Could have TPS emerged anywhere other than Japan?” And finally, “What, if anything, is Japanese about lean thinking?”
My attempt to address these questions – an ever-changing effort as I reflect more and the world around us keeps evolving – has taken the shape of the graph you see below, which illustrates what I call the “Toyota double funnels”. There are three main sections to the graphic:
- The left funnel represents a selection of key ingredients that, combined, have led to the creation of Toyota’s way of working.
- The spiral in the middle of the graphic represents the actual genesis of the Toyota Way, TPS, TPD, TMS and lean thinking, which can be traced back to a 30-year period of incubation, between 1950 and 1980.
- The right funnel represents the diffusion of this body of knowledge around the world, which started around the time of the NUMMI experiment, in 1984.

Michel Baudin‘s comments: As usual, John Shook’s post is both grounded in deep knowledge and well written. The infographic is also clear and the popup boxes of information attached to each item on Planet Lean are a valuable enhancement. But I still don’t buy everything in it.

New Year Lost and Found | John Shook | Planet Lean
“As many of us are wont to do, I reflected a bit over the holidays. As always, it wasn’t hard to find ample fodder on both sides of the hope vs despair ledger: we have so much cause for concern around us, but also plenty to rejoice about. […] This year’s reflection confirms what I’ve found over many years: when seeming to lose something of great value, if you look you can find that something new has come along to offer welcome and perhaps unexpected value.[…]
As a noteworthy attempt to shed light on the lean and digital muddle, I turn to Christoph Roser’s Industry 4.0 Discovery Bus Tour of Geeks. Christoph rented a bus and invited interested parties to join in a tour to try to figure out exactly what is all this noise about Industry 4.0. The Geeks visited 10 German factories that claim to be doing exemplary work, with Christoph blogging about the visits along the way. I encourage you to read the entire series of posts on his blog All About Lean.”

Michel Baudin‘s comments:
It’s wonderful to see LEI Chair John Shook recognize Christoph’s tour of Industry 4.0 as a highlight of 2019. The tour takes up half of his picture gallery. In his description, he got the essence right but a few details wrong. It wasn’t a “Bus Tour of Geeks” but a “Van Full of Nerds.”
It was a van because there were only 8 of us, and “nerds” at my insistence. Geeks are wannabee nerds and “nerds” was a more accurate description of Ralph Richter, Franck Vermet, Torbjørn Netland, Christoph Roser, Hironori Hibino, Kai Lorentzen, Mark Warren, and me.
We also visited 7 factories, not 10: Bosch (2 sites), ABB, Kärcher, Siemens, Trumpf, and Audi. In addition, we visited R&D labs, startups, and universities. Altogether, it was the most informative and densely packed tour I have ever been on or organized.
I agree with John Shook that Christoph’s posts about the tour are must-reads, as he covered every visit we made. I blogged about this trip in a complementary way, about tools and ideas that intrigued me rather than companies:
