What Exactly Is Jidoka?

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. Continue reading What Exactly Is Jidoka?

Toyota Standard Work – Part 3: Standard Work Layout

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 Standard Work – Part 2: Standard Work Combination Table

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. Continue reading Toyota Standard Work – Part 2: Standard Work Combination Table

Toyota Standard Work – Part 1: Production Capacity

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. Continue reading Toyota Standard Work – Part 1: Production Capacity

Disabled Employees in Manufacturing – Omron Taiyo in Japan – Part 2

In my last post, I started to describe the factory tour at Omron Taiyo, where more than half of the employees are disabled. This post continues this interesting tour, also looks into the financial situation of their employees, and gives some suggestions for other companies.

Disabled Employees in Manufacturing – Omron Taiyo in Japan – Part 1

In every country, a part of the population has temporary or permanent disabilities that handicap their working ability. While in Japan, I was able to visit two factories of Omron Taiyo, in Kyoto and Beppu, where the majority of the employees have a disability. This was quite an enlightening experience for me, and I would like to share it with you. Due to the length of this post, I have split it into two parts.

My Workshop Structure for Creative Problem Solving

In lean manufacturing – or in fact, in any kind of production system – you have to solve problems. Depending on the problem, you may need a creative solution and have to access the wisdom of the crowd. For this I have a workshop structure that I frequently use for problems that have lots of different options. Let me show you my workshop structure with which I’ve had quite good results.
