The Difference between the Toyota Production System and Lean Manufacturing

The Toyota Production System (TPS) is the archetype of lean manufacturing. Lean is often used as a synonym for the Toyota Production System, and that is generally quite accurate. It is also sometimes referred to as the “Westernized” version of the Toyota Production System. However, there are some smaller differences in the underlying approach, as well as some larger and often unintentional differences in its application. Let’s have a look!

On the Team Structure at Toyota

Toyota is (among other things) famous for its team structure on the front line. They have a quite low ratio of team members to supervisors, and I believe that is part of their success. Whereas many Western companies overstuff their hierarchy, at Toyota supervisors actually have the time to help their people and to also improve the operations. Let me dig deeper into that. This blog post was inspired by the new book by Baudin and Netland, Introduction to Manufacturing.

Akio Toyoda Steps Down as Toyota CEO

Somewhat surprising to industry insiders, the CEO of Toyota Motor, Akio Toyoda, announced on January 26 his resignation, and he will step down as CEO on April 1, 2023, to become the chairman of the board. Hence, I will have a look at his impact on Toyota. However, just to be warned, if you expect glowing praise, you should look elsewhere. I believe he changed Toyota, a company I love, in a worrisome way. I am definitely not a fan of his work. Granted, being a CEO is not easy, and he did have to lead Toyota through a couple of crises (Recall,s Corona, etc.). Compared to other CEO’s, he is probably somewhere around average. But I believe he had a negative influence on the Toyota corporate culture.

Toyota’s New Type of Flexible Assembly Lines—Takaoka Line #2

Toyota Takaoka EntranceFlexible assembly lines are well known at Toyota – except that there are two types of “flexible assembly lines.” The well-known one is making multiple different models on the same line. But Toyota has developed a new type of flexible assembly line, where the entire layout of the assembly line can be changed quickly and easily. Confusingly, this is also called a flexible assembly line, although Toyota itself does not even have a name for it (different from the West, Toyota focuses more on doing something, while the West often puts the most effort into a catchy name). Their pilot line is in the Takaoka plant. Let me show you.

Evolution of Process Placement at Toyota – Part 1

When setting up a new production – or even when rearranging an existing production – one important decision is how to arrange your processes. I have written a lot on line layout, but this post will look at how the arrangement of lines evolved at Toyota. Some of their insights are now accepted wisdoms in lean, but many companies still struggle with it. This post also looks into the manning of machines, especially multi-machine handling. The blog post is based on the appendix in the Toyota Handbook from 1973.
