This PDCA cycle diagram depicts a never-ending cycle of planning, doing, checking (or studying), and acting. It offers a straightforward and effective approach to problem-solving and change management. Before updating procedures and working practices, the PDCA cycle diagram is useful for testing improvement measures on a small scale. The PDCA/PDSA framework applies to all types of organizations. It can be used to improve any process or product by breaking it down into smaller steps or stages of development and exploring ways to improve each one. While PDCA/PDSA is a useful business tool, it can also be used to improve one's performance.
