Kaizen is a Japanese philosophy of continuous improvement that involves all employees making small, incremental changes to achieve significant long-term results. The term, which means “good change” or “improvement,” is applied to every aspect of business and even personal life to eliminate waste, increase quality, and enhance productivity. The Kaizen approach emphasizes a culture where every person is responsible for making continuous improvements, often using the Plan-Do-Check-Act (PDCA) cycle.
