Shewhart Cycle

The Shewhart Cycle, also known as the PDCA cycle (Plan-Do-Check-Act), is a method for continuous improvement. It involves planning a change or solution, implementing it, checking the results to see if goals are met, and then acting based on what was learned—either maintaining the change, refining it, or starting the cycle again. This iterative process helps organizations systematically improve processes, reduce errors, and increase efficiency over time. It encourages a structured approach to problem-solving and process management.
