Kaizen and continuous improvement
Kaizen means “change for the better”: the ongoing improvement of processes, quality and working conditions by everyone in the organization, run as a management system rather than a one-off program. It ranges from small daily improvements by individual operators to focused kaizen events run by a cross-functional team, and it runs on the Plan-Do-Check-Act cycle so every change is tested, checked and made the new standard. These guides cover the principles, the types of kaizen, how to run events and projects, and how to build a culture where improvement lasts.

FAQ
Questions about kaizen and continuous improvement
Teamwork, personal discipline, improved morale, quality circles and suggestions for improvement. All five need to be in place at the same time for kaizen to work as a continuous improvement system rather than a periodic improvement program.
Daily kaizen is the small improvements operators make within their own authority. A kaizen event, also called a kaizen blitz or rapid improvement event, is a structured three-to-five-day workshop in which a cross-functional team works full time on one defined process problem, puts countermeasures in place and updates standard work before the event closes.
Plan, Do, Check and Act. Walter Shewhart developed the cycle at Bell Laboratories and W. Edwards Deming popularized it in Japan, where it became the structure through which every kaizen change in the Toyota Production System is designed, tested, verified and standardized.
No. Continuous improvement is a broad philosophy of making systematic, incremental improvements that applies across industries and functions. Lean manufacturing is a specific production management system with defined structural elements and a focus on customer value, and it includes continuous improvement as one of its five core principles.
