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.

Heroes save the day. Heroes turn around the disaster and rescue the puppy from the burning building. Heroes are admired, and everybody wants to be one. Everybody wants a hero when they need one.
But what about the people who prevent the need of a hero? What about the people that make sure the disaster never happens? What kind of people do you really need in your company? Continue reading Heroes, Firefighting, and Corporate Culture
The Japanese work ethic is pretty amazing, and their work standards are among the best of the world. In previous posts I have often written very favorably on these standards. Yet, not all is right in the Japanese working world. In fact, a lot is wrong and troublesome, and this superior work performance comes at a significant cost of work-life balance. Continue reading The Dark Side of Japanese Working Society
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. Continue reading The Toyota Employee Evaluation System
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. Continue reading Anatomy of the Toyota Kanban
Perhaps you’ve heard of the Japanese word monozukuri (sometimes written as 物作り, but most often written as ものづくり). Literally translated, it means to make (zukuri) things (mono). Yet, there is so much meaning lost in translation. A better translation would be “manufacturing; craftsmanship; or making things by hand.” However, this translation also does not give justice to the weight and influence this idea has in Japan. Let me take you on a tour of the Japanese culture of monozukuri. Continue reading Monozukuri – Japanese Work Ethics
In a previous post I wrote about the relation between utilization, fluctuation, and waiting time, and its approximation by the Kingman formula. Let me show you a quick and easy dice game where we simulate a supermarket checkout to let participants experience the effect of utilization, fluctuation, and the (worse) combined effect of both. Continue reading A Small Dice Game for the Kingman Formula
The spaces around your assembly locations are most precious. In my previous post I explained how to relocate or reduce the overall material quantity. In this post I focus on how to better use the area facing the worker. Ideally, all material should be within easy reach of the worker.
