Kaizen (改善, Japanese for "improvement") is a Japanese philosophy that focuses on continuous improvement throughout all aspects of life. When applie to the workplace, Kaizen activities continually improve all functions of a business, from manufacturing to management and from the CEO to the assembly line workers. By improving standardized activities and processes, Kaizen aims to eliminate waste (see Lean manufacturing). Kaizen was first implemented in several Japanese businesses during the country's recovery after World War II, including Toyota, and has since spread to businesses throughout the world.
