PDCAby: Diane Cho 304830

• PDCA (Plan-do-check-act or Plan-do-check-adjust): It is a 4-step management method used for control and continuous improvement of processes and products.

• Popularized by Dr. W. Edwards Deming who referred to this process as the “Shewart cycle.” Later in his career modified PDCA to PDSA (Plan, Do, Study, Act)

• Originally based on the scientific method where it uses “hypothesis-experiment-evaluation” in other words “plan, do, and check”

• The fundamental process is repetition. Repeating the PDCA can bring us closer to the goal.

• In Six Sigma, the PDCA cycle is called the DMAIC (define, measure, analyze, improve, and control)
