Frequently Asked Questions
No, while it originated in manufacturing (particularly Toyota), it is now applied in healthcare, software development, personal productivity, and many other fields.
Kaizen focuses on continuous, small, incremental improvements to existing processes. Innovation typically involves discontinuous, breakthrough changes or creating something entirely new.
It is occasionally used as a verb in business jargon (e.g., 'to kaizen a process'), but this is non-standard. The noun form is far more common and recommended.
The closest direct phrase is 'continuous improvement,' but 'kaizen' carries the specific cultural and methodological connotations of the Japanese lean philosophy.
