Which problem-solving process is most commonly associated with Six Sigma?

• A. PDCA
• B. 8D
• C. FMEA
• D. DMAIC

Answer: (D)

DMAIC is the problem-solving cycle most associated with Six Sigma. It provides a clear, data-driven route: Define the problem and goals, Measure the current performance with data, Analyze the data to uncover root causes, Improve by implementing solutions to address those causes, and Control the process to sustain the gains. This framework guides Six Sigma projects from identifying the issue through to lasting results, supported by statistical tools and structured roles. Other methods like PDCA (a general continuous-improvement loop), 8D (team-based problem solving used in various industries), and FMEA (risk assessment to prevent failures) are valuable tools, but DMAIC is the specific process framework that defines Six Sigma improvements.
