JM: Training within Industry – Job Methods

by

Job Methods is the TWI module focusing on improving the workplace. The method is a basic four-step process focused on optimizing mechanical work. The underlying approach is good. The documents from 1945, however, put the improvement squarely on the shoulders of the supervisor.

My belief is that the workers should be involved much earlier and that the decision of what to improve would also benefit from more attention. But the basic method is still sound. The TWI people also saw this problem, but their management told them that it is “good enough.” Hence this module saw a lot of improvements after 1945. Yet, it was the smallest of the three main programs. Let me show you the TWI Job Methods in more details. This is the fourth in a series of five posts on TWI.

JI: Training within Industry – Job Instructions

by

Arguably the most successful module of Training within Industry is Job Instructions, or JI for short. JI has a precise focus on one topic: how to train your workers. The method is very simple and basic but works well.

Of course, there are some limitations. The process works well with pretty much any type of work, but it is best done one-on-one, as it was intended. It is not well suited for classroom teaching of larger groups; the trainer does need to invest time and attention to every individual student. But overall a very useful method. This is the second in a series of five posts on TWI.

Training within Industry – TWI – Oldies but Goldies

by

We Can Do It!Training within Industry – or TWI for short – was a US program during World War II. It significantly improved industrial production and helped the Allies to win the war. While the ideas date to the 1940s, they are still very relevant. In my view, they are pure gold if you have to manage a shop floor. It is to me the best overarching system for training and managing workers, and it significantly influenced Toyota.

While technology has changed a lot since 1945, people have not. The methods of TWI still work, and can really help you to improve. Even better, the original US government documents from 1945 are all in public domain. Let me introduce you to TWI. This is the first in a series of five posts on TWI.

Taiichi Ohno’s Chalk Circle

by

Chalk CircleOne of the famous teaching methods by Taiichi Ohno is the chalk circle. The method itself is simple. A circle is drawn on the shop floor near a point of interest. A disciple is put in the circle and told not to leave it until he is picked up again by the teacher.

In this post I will explain a bit about the chalk circle, how to use it for teaching, and how to use it for yourself.

Poka yoke anyone?

Mistake proofing (or Poka Yoke in Japanese) is one important way to avoid waste in lean manufacturing. In this post, I will present a small game that can be used to teach the basics of poka yoke easily and quickly. The game is based on Kinder Surprise eggs made by Ferrero, also known as a Kinder Egg. These eggs are available almost anywhere – except in the US, in which case there are some alternatives.
