PDCA: PDCA (Plan-Do-Check-Act) is a continuous improvement methodology used to enhance processes and systems. It involves four stages: planning (setting objectives and processes), doing (implementing the plan), checking (monitoring results), and acting (adjusting the process based on feedback). The PDCA cycle is widely used in quality management and operational excellence initiatives.
