The PDCAサイクル, or Plan-Do-Check-Act cycle, is a continuous improvement model used in various fields, including business and quality management. It consists of four stages: planning a change, implementing it, checking the results, and acting on what has been learned. This cycle helps organizations systematically improve processes and products. By repeating the PDCAサイクル, teams can refine their strategies and enhance efficiency over time. Each iteration allows for adjustments based on feedback and results, fostering a culture of ongoing improvement and adaptability in response to changing conditions or challenges.
