Taiichi Ohno (1912 – 1990) was a successful Japanese engineer and the founding father of the Toyota Production System (TPS). This became later the LEAN Management philosophy which is still used in today’s business and manufacturing world.

Biography Taiichi Ohno

Taiichi Ohno graduated of the Nagoya Technical High School in Japan.

After graduation between the World Wars, Taiichi Ohno joined in 1932 the Toyoda family in their first business of Spinning. This was later sold to a British company named the Platt Brothers. After selling the business, the Toyoda family decided to invest the money in manufacturing motor cars (Toyota).

In 1943 Taiichi Ohno worked as a production engineer and met the challenge to boost their productivity during the competitive America car Industry. This was a matter of survival for the Toyoda family which gave a big pressure.

Luckily during the following years, Taiichi Ohno manage the situation and decided to eradicate inefficiency and eliminate waste within the his production process. This became the core for the Toyota Production System (TPS).

Elements like muda (the elimination of waste), jidoka (the injection of quality) and Kanban (the tags used as part of a system of Just In Time stock control) were designed, developed, tested and optimized.

He also kept asking repeatedly why the company needed to (expensively) stockpile vast quantities of components for its production line. Here the Just In Time (JIT) method of stock control was born.

Taiichi Ohno worked his way up from shop-floor supervisor to an executive within Toyota. Later in his career he was sent to consult with suppliers.
The success of the TPS was helped to some extent by the fact that Toyota’s main factory in Japan is situated in Toyoda City, near Nagoya. It was also for Toyota to choose parts on demand and ensure that they arrived at its doors precisely as and when it needed them.

Taiichi Ohno ‘s success of TPS development (Daily Improvements, Good Thinking and Good Products) within Toyota was spread to some extent by the telling of his story in books and articles translated into English.

He was an great originator of new ideas, combined with an unique management style. Taiichi Ohno had the ability to identify the best of a competitor’s systems and to adapt these to the Japanese manufacturing and business environment. This was one of the key successes of the growth of Toyota as a car manufacturer and organization.

Taiichi Ohno quotes

  1. “All we are doing is looking at the time line, from the moment the customer gives us an order to the point when we collect the cash. And we are reducing the time line by reducing the non-value adding wastes.”
  2. “Progress cannot be generated when we are satisfied with existing situations.”
  3. “The Toyota style is not to create results by working hard. It is a system that says there is no limit to people’s creativity. People don’t go to Toyota to ‘work’ they go there to ‘think’.”
  4. “Without standards, there can be no improvement.”
  5. “Having no problems is the biggest problem of all.”
  6. “Standards should not be forced down from above but rather set by the production workers themselves.”
  7. “Something is wrong if workers do not look around each day, find things that are tedious or boring, and then rewrite the procedures. Even last month’s manual should be out of date.”
  8. “Data is of course important in manufacturing, but I place the greatest emphasis on facts.”
  9. “The more inventory a company has, the less likely they will have what they need.”
  10. “No goal, regardless of how small can be achieved without adequate training.”
