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

Ford and Toyota

“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.

[…]I believe the spread of lean has been both a matter of diffusion and of dilution.[…] Along with the dilution, there’s been more than a little delusion, aided by consultants selling things under the name of “lean” that are far from the original intent of the thinking, system, and application.”

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.

What is the science in Lean? | Jeffrey Liker | The Leadership Network

“Scientific thinking can be defined as the intentional coordination of theory and evidence, whereby we encounter new information, interpret it and, if warranted, revise our understanding accordingly. In fact, we learn the most when we explicitly state what we expect and compare it to what actually happens. […] This is where practicing PDCA comes in, and Toyota’s view on being scientific.[…] Just explaining the concept of PDCA is not enough to change behavior and mindset, and there are not many master teachers like Ohno to go around — who have an intuitive feel for what to ask next to push the right buttons to help the student learn through practice. This is the reason for the Improvement Kata and Coaching Kata — to have a structured approach to learning and teaching scientific thinking so it can be deliberately practiced by anyone..”

Michel Baudin‘s comments: Is there science to Lean, TPS, or, more generally, manufacturing? There is definitely technology and there is management. Technology is about getting inanimate objects to do what we want them to; management, about working with people. Science is not about getting anything done but about understanding how nature works.

A Rose By Any Other Name,… Don’t Even Try!

Whether you name a company, a product, a machine, a person, a role,… or serialize units in production, you create a key to which information about an entity can be attached and through which it can be retrieved. When you do it, you should think through the different ways the name will be used and, once you have made your choice, stick with it.

These are obvious principles, but not always respected in manufacturing organizations.  It hadn’t occurred to me to post about this until I saw, in yesterday’s New York Times, an unintelligible tennis women champions’ board from Wimbledon, from photographer Duncan Grove,  with annotations  to decrypt it:

The simple, straightforward choice would have been to designate these winners by the full names under which they were referenced in the media and list multiple winners under the same name for all wins. The board maintainers at Wimbledon could also have asked the honorees what they wanted to be called. Their marital status is irrelevant and, if married, so are their obscure husbands’ last names and initials, particularly for the women who won both before and after marriage, or had several spouses. The key takeaway: when naming, forget obsolete traditions.

Managers Should Rethink Rational Decision-Making | Michael Ballé | McGrawHill BusinessBlog

“Managing is making decisions, right? Managing well is making rational decisions – or so we’re told. We’re so steeped in a culture of “rationality” that we’re no more aware of it than a goldfish is aware of the water in the bowl. Yet rationality is a made-up thing, a construct, invented in Germany in the XIXth (as opposed to “reason” or being reasonable, which has been around for a much longer time and is much harder to define). Rationality implies that our actions are in line with the outcomes we seek – the reasons for these actions – premised on the idea that our beliefs are in line with our reasons to believe….”

Max Weber

Michel Baudin‘s comments: The title of the article appears to promote irrational decision making, which should be a hard sell. Michael Ballé seems to know what a goldfish is aware of, and I wonder how. According to Etymology OnLine, “rationality” actually is a 17th-century French word and, to this day, means the quality of being based on reason, not of being “aligned with a goal.” The German connection, perhaps, is Max Weber who described goal alignment as one of two subcategories of rationality in social behaviors (“Zweckrationalität”) in Economy and Society, a book published in 1922, after his death — that is, in the 20th century, not the 19th.

Kaoru Ishikawa

If you are a Lean expert, no one expects you to discuss German philosophy. If, however, you choose to go there, it helps if you start with a paragraph that withstands a 5-min fact check on Google. For an analysis of management decision making, I prefer to start with what Kaoru Ishikawa said in his book on TQC.

What Is Cost?

Costs are the object of heated arguments when working to improve manufacturing operations, with participants assuming that the notion of cost itself is self-evident while, in fact, they understand it differently and talk past each other. This is an attempt to bring some clarity to the subject.

New Karakuri Kaizen Video From Toyota

My colleague Kevin Hop drew my attention to this video of Kazuhiko Furui showing some examples of Karakuri Kaizen at Toyota, the training of Toyota employees in coming up with new devices, and the iterations that go into making them work. It goes deeper into the topic than the videos I had posted earlier.

This is part of a series of videos called econohito, that shows actions by Toyota employees to avoid wasting power or water, and to collect electricity from solar panels. Perhaps the best way forward for sustainable development would be to shift away from cars altogether, but that’s not what this is about.
