Abstract

There still seems to be much confusion today surrounding W. Edwards Deming’s plan-do-study-act (PDSA) cycle. How did Deming’s PDSA cycle evolve? Did Deming create the plan-do-check-act (PDCA) cycle? Are PDCA and PDSA related? In the 1950s, W. Edwards Deming brought the scientific method to industry. Later, the method was called the plan-do-study-act (PDSA) cycle. Deming built the method from many problem-solving theories, including Shewhart’s specification, production and inspection process. PDSA remains one of today’s most popular problem-solving methods and continues to evolve.
