A Japanese business philosophy focusing on continuous, incremental improvement involving all employees from management to workers. It emphasizes making small, ongoing positive changes that collectively result in significant improvements over time.
From Japanese 'kai' (change) + 'zen' (good), literally meaning 'change for better.' The concept has ancient roots in Japanese culture but was formalized in business during post-WWII reconstruction, then adopted globally after Toyota's success demonstrated its effectiveness in manufacturing and beyond.
Kaizen proves that tortoise beats hare in business improvement - while companies chase dramatic breakthroughs, kaizen practitioners make tiny daily improvements that compound like interest. A 1% improvement every day results in being 37 times better after a year, which is why Toyota could overtake Detroit despite starting decades behind!
