Which statement best describes the D step in DMAIC?

• A. D=define customers, project boundaries, and processes
• B. M=measure performance
• C. A=analyze data to identify causes of variation, gaps in performance, and prioritize actions
• D. Control the process to prevent reverting

Answer: (A)

Define is the phase that sets up the project by clarifying who the customers are, what they require, the project boundaries, and which processes are in scope. This establishes the problem statement and goals and determines what will be measured later. The other statements describe the Measure phase (tracking performance), the Analyze phase (identifying causes and prioritizing actions), and the Control phase (preventing regression).
