The PDCA method, also known as the Deming Cycle or Plan-Do-Check-Act, is a continuous improvement process used in business management. It involves four stages: Plan, where a problem or goal is identified and a plan is developed; Do, where the plan is implemented; Check, where the results are evaluated and compared to the initial goal; and Act, where adjustments are made to improve the process. This method promotes a systematic and iterative approach to problem-solving and encourages organizations to constantly strive for improvement. It is widely used in quality management and has been proven to be an effective tool for achieving long-term success and sustainability in business operations.
