Jidoka is a term commonly used in lean manufacturing, and widely considered one of the pillars of the Toyota Production System, the other being Just in Time (JIT). However, while the word jidoka is often used to impress others, the ideas behind it are much less frequently found outside of Toyota. Maybe this is because so many people interpret jidoka differently. In this first post of a three post series on jidoka, we look at what jidoka actually is.
This post is the third in this series on how Toyota plans standard work. The first one was the production capacity sheet to define what capacity you have available. The second one was a standard work combination table to define when the operator is doing what. Finally, the third of the “famous three slips”, presented in this post, is a standard work layout sheet to help the layout and arrangement of the machines.
Toyota has a nifty way to plan the work of an operator using their standard work charts. In my last post I explained the production capacity sheet to define what capacity you have available. In this post we will talk about the second of the “famous three slips”, the standard work combination table to define when the operator is doing what. A subsequent post will show a standard work layout sheet.
Toyota is excellent with their standard work. They use a series of worksheets to simplify the creation of these standards. These are sometimes also know as the “famous 3 slips”. The first one is a production capacity sheet to define what capacity you have available. The second one is a standard work combination table to define when the operator is doing what. The third one is a standard work layout sheet to help with the layout and arrangement of the machines. While there are many different ways of doing this, I like the Toyota approach. Since this is a larger topic, I’ve broken it into multiple blog posts. Lets start with the Production Capacity sheet.
This was extremely insightful, and I learned a lot about the differences between the Japanese car makers. Let me give you an overview and some details on Toyota plants before firing off a series of blog posts on the different Japanese automotive companies.
Toyota is one of the the most visionary car makers with respect to its manufacturing. They continuously and radically evolve and update their production system. Recently I learned about their new “flexible assembly line.” Now, you’ve probably heard about Toyota’s flexible assembly lines producing multiple products on the same line. That is old hat; they’ve done that for thirty years. Their new flexible assembly line involves a completely different aspect of flexibility, with which Toyota surprised me (again). Let me show you …
Like most companies, Toyota conducts an annual evaluation of the performance of their employees. Recently I got a chance to look at these evaluation sheets and take notes. There are some surprising differences in the evaluation by Toyota in comparison to the evaluation by most other companies.
While Toyota did not invent the pull system, they did invent kanban, the genius idea of using cards of paper (and later other forms of information) to create a pull system for mass-produced goods. I recently was able to take pictures of Toyota kanbans, and would like to show and explain them to you.
