Six Sigma Black Belt Practice Exam 2025 – Complete Prep Resource

DMAIC is a structured problem-solving methodology used in Six Sigma for process improvement, consisting of five distinct phases: Define, Measure, Analyze, Improve, and Control. Each of these phases plays a critical role in guiding teams to systematically identify and eliminate defects, improve processes, and ensure sustained improvement.

The "Define" phase involves clearly establishing the problem, project goals, and customer requirements. The "Measure" phase focuses on gathering data and understanding current performance levels. The "Analyze" phase is dedicated to identifying root causes of issues by analyzing the data collected.

In contrast, "Determine" is not part of the DMAIC framework. While it might seem relevant to decision-making processes, it does not correspond to any recognized phase within the DMAIC model. Understanding this distinction is essential for effectively navigating process improvement initiatives in a Six Sigma environment.
