Life and work
Late-1950s Imai worked for five years in Washington DC at the Japanese Productivity Center, where he was responsible to accompany groups of Japanese businessmen on visits to American plants. In 1962 in Tokyo he founded his own Employment agency for the recruitment of management, executive and research personnel.
In 1986 he founded the Kaizen Institute Consulting Group (KICG) to help western companies to introduce the concepts, systems and tools of Kaizen. In the same year he published, in Japan, the book on business management "Kaizen: Japanese spirit of improvement", which helped popularizing the Kaizen concept in the West.
Kaizen, Japanese for "improvement" or "change for the best", refers to philosophy or practices that focus upon continuous improvement of processes in manufacturing, engineering, and business management. It has been applied in healthcare, psychotherapy, life-coaching, government, banking, and other industries. Imai (1986) acknowledged that Kaizen starts with detection of needs and problem definition:
- The starting point for improvement is to recognize the need. This comes from recognition of a problem. If no problem is recognized, there is no recognition of the need for improvement. Complacency is the archenemy of KAIZEN.
- 'Kaizen' means ongoing improvement involving everybody, without spending much money. When 'Kaizen' was first published here in 1986, many U.S. products were of poor quality, and Japanese-made products were gaining market share. Since then, American companies have made great strides in improving product quality, and much of that is attributable to their implementation of kaizen principles, which incorporate TQM.
