What is the first step in Dr. W. Edwards Deming's PDCA cycle?

The first step in Dr. W. Edwards Deming's PDCA (Plan-Do-Check-Act) cycle is the Plan Phase. This phase is crucial as it sets the foundation for the entire cycle by identifying a problem or opportunity for improvement, defining objectives, and determining the necessary actions to achieve those objectives.

During the Plan Phase, teams engage in thorough planning that includes gathering data, understanding current processes, and analyzing the situation to determine what changes will lead to improved outcomes. Effective planning ensures that the subsequent steps of doing, checking, and acting are based on a well-defined strategy, ultimately enhancing the likelihood of successful implementation and improvement.

The subsequent phases—Do, Check, and Act—are built upon the insights and plans developed in this initial phase, making it integral to the overall process of continuous improvement advocated by Deming.
