The Japanese word kaizen, found in Japanese dictionaries, simply means "change for better", with the intrinsic meaning of “on-going” and “continuous,” and is in everyday use. The word refers to any improvement, large or small, with the same meaning as the English word “improvement”. The term Kaizen was first used by the Toyota manufacturing plant to identify this approach as a concept for business, particularly in the industrial sense. The word "kaizen" in English terms has been incorporated to provide a measurement for implementing continuous improvement and is synonymous with this phrase.
