In different literature about Toyota the term “Quality Circle” is also used.
Typical improvements achieved by a single Kaizen are: (Wiley, 1999, p.3,7)

|The typical budgets for these projects are 300-400$ plus labor.|

History of Kaizen
Since the definition of Kaizen is quite broad, there are several different
thoughts about the history of Kaizen. The most common version is that
it resulted from the competition between Nissan and Toyota.
The fact that Nissan won the Deming Price for quality in 1961 drove
Toyota even more aggressive in its approach to lean manufacturing.
Toyota therefore vowed that it, too, would win the Deming price. In
order to overcome certain quality issues Shigeo Shingo elaborated a
poke-yoke system. Based on the experience gathered during the
elaboration Tetsuichi Asaka and Kaomi Ishakawa developed the Toyota
Quality Circles in 1962. These Quality Circles were later called the first
real Kaizen event. In the same year Masaaki Imai founded the Kaizen
Institute, which promoted the Kaizen approach through the world.
Other theories about the origin of Kaizen are described in the paragraph
“Impact of cultural differences Japan, US, Europe” (Mika, 2000, p.5 )
