History of Kaizen
• In 1986 Masaaki Imai introduced to the Western world the Japanese term Kaizen and
made it famous through his book, Kaizen: The Key to Japan's Competitive Success.
Translated in fourteen languages, Kaizen became a fad the world over.
• In 1997 Imai introduced an evolved form of Kaizen in his book Gemba Kaizen: A
Commonsense, Low-Cost Approach to Management, to reassert the importance of the
shop floor in bringing about continual improvement in an organization. In essence, that
translates into something of a corporate 'back to basics' philosophy. Gemba is where the
product is actually manufactured, which could mean the assembly line in a
manufacturing plant or the place where employees interact with customers in the service
sector. It is "the place where the real work is done", as Imai likes to put it.
What is Kaizen in manufacturing?

costs, and greater customer satisfaction.

minimizing manufacturing waste.
