Six Sigma Green Belt Certification Practice Exam 2025 - Free Six Sigma Practice Questions and Study Guide

The acronym DMAIC stands for Define, Measure, Analyze, Improve, and Control, and it is a fundamental framework used in Six Sigma for process improvement. Each phase serves a specific function in driving projects toward performance improvement.

- In the Define phase, project goals and customer requirements are identified, ensuring that the project is aligned with customer needs.

- The Measure phase involves gathering data on current processes to establish baselines and quantify existing problems.

- In the Analyze phase, data is analyzed to identify root causes of problems, enabling teams to understand what factors are contributing to the defects or inefficiencies.

- The Improve phase is where solutions are developed and implemented to address the root causes identified previously, thereby enhancing the process.

- Finally, in the Control phase, measures are put in place to sustain the improvements over time and ensure that the process continues to meet performance standards.

The other options present variations of the DMAIC terms but don’t correctly represent the established and recognized framework in Six Sigma, which is crucial for ensuring consistency and effectiveness in process improvement initiatives.
