The Define, Measure, Analyze, Improve, and Control (DMAIC) methodology is the core framework of Six Sigma, a data-driven process improvement approach that aims to reduce defects, enhance efficiency, and optimize performance.
(A) Correct – Six Sigma.
DMAIC is a structured Six Sigma methodology used for problem-solving and process improvement.
It helps organizations identify inefficiencies, eliminate errors, and standardize processes.
(B) Incorrect – Quality circle.
A quality circle is a group of employees who meet to discuss and resolve work-related issues, but it does not follow the structured DMAIC approach.
(C) Incorrect – Value chain analysis.
Value chain analysis focuses on evaluating business activities to improve competitive advantage, not structured process improvement like Six Sigma.
(D) Incorrect – Theory of constraints.
The Theory of Constraints (TOC) focuses on identifying and eliminating bottlenecks in processes, but it does not use the DMAIC approach.
