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.
Shigeo Shingo is a name that everyone in the United States lean community knows. He is sometimes considered “the world’s leading expert on manufacturing practices and the Toyota Production System,” an “engineering genius,” and the foremost guru of lean production. Some sources even claim he invented the Toyota Production System and taught Taiichi Ohno. Shingo greatly helped to popularize the idea of Lean in the USA. However, he invented much less than what is sometimes claimed, and there is also quite some disagreement in the lean community on this. Let’s have a look at his life and his achievements.
