Which option correctly states the acronym DMAIC?

• A. Plan, Do, Check, Act
• B. Define, Analyze, Measure, Improve, Control
• C. Define, Measure, Control, Analyze, Improve
• D. Define, Measure, Analyze, Improve, Control

Answer: (D)

The sequence used in the DMAIC framework is being tested. The correct order is Define, Measure, Analyze, Improve, Control. Start by defining the project—its goals, scope, and CTQs (customer, time, cost, quality). Then measure the current process to establish a baseline and quantify performance. Next, analyze the data to uncover root causes of defects or variability. After understanding causes, develop and implement improvements to address them. Finally, put controls in place to sustain the gains and prevent regression.

The other options mix in a different cycle (Plan-Do-Check-Act) or reorder steps in ways that break the data-driven flow: measuring before analysis is essential, and implementing improvements without first analyzing causes or establishing controls undermines sustainability.
