See on Scoop.it – lean manufacturing
“Underpinned by thirteen core processes and philosophies, The Toyota Production System pioneered modern manufacturing as we know it. Here’s what each one is and how each one works. The Toyota Production System is the blueprint for modern manufacturing, and is employed in Britain to build the Toyota Auris and Avensis models. Here, we take a look at the thirteen philosophies that underpin it.”
Thanks to Mark Graban for drawing my attention to this blog from Toyota UK and this article in particular. It is always useful to know Toyota’s official line about its own system. Corporate blogs are perversions of the concept of a blog, which is intended to be a conversation between an individual human and the rest of the world. When you read a post, you know who stands behind it and who will respond to your comments. Corporate blogs lack this authorial voice, and are a public relations exercise.
The first “pillar” in this article is the Konnyaku stone. I had never heard of it The only kind of Konnyaku I am familiar with is gelatinous slabs found in Japanese dishes. I didn’t know the name was used in polishing sheet metal, and I am still not sure what kind of a pillar of a production system it may be.
The picture illustrating the Andon paragraph does not appear related to the subject. An Andon board, on the other hand, is shown as an illustration of Kanban.
The picture on Jidoka shows automatic welding by robots, but the text only describes equipment “designed to detect problems and stop automatically when required,” without saying that it happens to be automatic. The paragraph also describes operators stopping production “the moment they spy something untoward,” which, while important, is not jidoka per se.
“Kaizen” is described as “a mantra for continuous improvement.” I thought it was just continuous improvement, not a mantra for it. The paragraph also states that it achieves “efficiency optimization.” If it did, however, you would be at an optimum, and continuous improvement would no longer be possible.

The GM Toyota Rating Scale | Bill Waddell
See on Scoop.it – lean manufacturing
“In a survey of suppliers on their working relationships with the six major U.S. auto makers – Toyota, Honda, Nissan, Ford, Chrysler and GM – GM scored the worst. But of course they did. They are GM and we can always count on such results from them. […] Toyota scored highest with a ranking of 318, followed by Honda at 295, Nissan at 273, Ford at 267, Chrysler at 245, with GM trotting along behind the rest with an embarrassing 244.”
While I am not overly surprised at the outcome, I am concerned about the analysis method. The scores are weighted counts of subjective assessments, with people being asked to rate, for example, the “Supplier-Company overall working relationship” or “Suppliers’ opportunity to make acceptable returns over the long term.”
This is not exactly like the length of a rod after cutting or the sales of Model X last month. There is no objective yardstick, and two individuals might rate the same company behavior differently.
It is not overly difficult to think of more objective metrics, such as, for example, the “divorce rate” within a supplier network. What is the rate at which existing suppliers disappear from the network and others come in? The friction within a given Supplier-Customer relationship could be assessed from the number of incidents like the customer paying late or the supplier missing deliveries…
Such data is more challenging to collect, but supports more solid inferences than opinions.
