Which of the following is NOT a step in the Six Sigma Problem-Solving Approach?

In the context of the Six Sigma Problem-Solving Approach, the steps involved are commonly summarized using the DMAIC framework, which stands for Define, Measure, Analyze, Improve, and Control. Each of these steps plays a critical role in identifying and resolving issues to improve processes.

The steps "Define," "Analyze," and "Control" align perfectly with the established phases of DMAIC. "Define" involves clearly articulating the problem and outlining project goals, while "Analyze" focuses on digging into the data to discover root causes. "Control" is about maintaining improvements over time and ensuring that solutions are effective.

"Manage," on the other hand, is not recognized as a formal step within the DMAIC process. Instead, the process emphasizes the importance of "Measure" and "Improve" as distinct phases crucial to achieving Six Sigma quality. This distinction clarifies why "Manage" stands out as not being part of the established Six Sigma framework.
