Questions & Answers

Q: Who is considered the father of the Tokyo Production system and the creator of Just-In-Time manufacturing?

Chihiro Ohno, a Japanese industrial engineer and businessman, is considered the father of the Tokyo Production system and the creator of Just-In-Time manufacturing.

Q: What is the 7 wastes concept in JIT manufacturing?

The 7 wastes, also known as Buddha in Japanese, are non-value-adding activities in the manufacturing process. These wastes include overproduction, waiting, transportation, excess processing, inventory, unnecessary motion, and defects.

Q: Why did JIT manufacturing become popular in Japan after World War II?

Japan's lack of cash for big batch production methods, limited space for large factories, scarcity of natural resources, and high unemployment led them to adopt JIT. Smaller factories, low inventory levels, and efficient use of resources became the key focus.

Q: What replaced the term "just-in-time" in the 1990s?

The term "just-in-time" was replaced by the term "lean manufacturing" in the 1990s as the preferred term to describe the efficient production methodology.

Summary & Key Takeaways

• Just-in-Time (JIT) is a manufacturing technique developed by Chihiro Ohno, a Japanese industrial engineer and businessman, that emphasizes reducing waste and inventory levels.

• Ohno devised the concept of the 7 wastes, also known as Buddha in Japanese, as part of the JIT system.

• JIT manufacturing became popular in the 1980s but was later overshadowed by the term "lean manufacturing" in the 1990s.
