Taiichi Ohno & Seven Wastes

TOYOTA

Taiichi Ohno (大野耐一 Ōno Taiichi, February 29, 1912 – May 28, 1990) was a Japanese industrial engineer and businessman. He is considered to be the father of the Toyota Production System, which became Lean Manufacturing in the U.S. He devised the seven wastes (or muda in Japanese) as part of this system. He wrote several books about the system, including Toyota Production System: Beyond Large-Scale Production.

Ohno’s principles influenced areas outside of manufacturing, and have been extended into the service arena. For example, the field of sales process engineering has shown how the concept of Just In Time (JIT) can improve sales, marketing, and customer service processes.

Ohno was also instrumental in developing the way organisations identify waste, and is also know for his Ten Precepts. Credited as the “father” of the Toyota Production System, Ohno originally identified seven forms of muda (無駄, meaning “futility; uselessness; wastefulness).

Seven Wastes

1. Waiting
2. Overproduction
3. Over Processing
4. Transport
5. Unnecessary Motion
6. Inventory
7. Defects

Ten Precepts

1. You are a cost. First reduce waste.
2. First say, “I can do it.” And try before everything.
3. The workplace is a teacher. You can find answers only in the workplace.
4. Do anything immediately. Starting something right now is the only way to win.
5. Once you start something, persevere with it. Do not give up until you finish it.
6. Explain difficult things in an easy-to-understand manner. Repeat things that are easy to understand.
7. Waste is hidden. Do not hide it. Make problems visible.
8. Valueless motions are equal to shortening one’s life.
9. Re-improve what was improved for further improvement.
10. Wisdom is given equally to everybody. The point is whether one can exercise it.
