Define, measure, analyze, improve, control (DMAIC), developed by W. Edwards Deming in the 1950s, is a statistical and analytical method used to reduce defects by finding the root causes of defects, eliminating them, and sustaining that improvement level.
The roots of DMAIC are from the plan-do-check-act (PDCA) cycle, a method for learning and improvement, also referred to as the “Shewhart Cycle,” developed by Walter Shewhart, the statistician who developed statistical process control (SPC) while employed at Bell Laboratories during the 1930s.
Deming successfully applied the concept of PDCA to the management system processes of industrialized organizations during the 1950s and PDCA became known as the “Deming Wheel.” Deming developed DMAIC to guide quality projects of existing business processes in a continuous effort to reduce defects.
