The DMAIC sequence (Define, Measure, Analyze, Improve, Control) is used to improve which?

• A. New products
• B. Existing products
• C. Process reengineering
• D. Compliance auditing

Answer: (B)

DMAIC is a structured, data-driven approach used to improve existing processes by reducing defects and variation. It guides teams through defining the problem in the current process, measuring baseline performance, analyzing data to uncover root causes, implementing improvements to address those causes, and putting controls in place to sustain the gains. This focus on refining an ongoing process fits improving existing operations, not creating something new. It’s not about radical redesign (that would be a different approach) and it isn’t about compliance auditing, which centers on checking adherence to standards rather than systematically enhancing process capability. For example, if a production line has too many defects, DMAIC would map the current steps, collect defect data, identify root causes, implement fixes, and establish controls to keep the improvements stable.
