The primary focus of the Analyze phase in the DMAIC (Define, Measure, Analyze, Improve, Control) methodology is to identify root causes of defects. This phase follows the data collection and measurement processes established in the earlier stages. The purpose here is to delve into the data collected to uncover the underlying issues contributing to the problems identified in the Define phase.

In this context, tools such as cause-and-effect diagrams, process mapping, and statistical analysis are commonly employed to dissect the problem and pinpoint the sources of variation or defects. By identifying these root causes, teams can develop targeted strategies in the subsequent Improve phase, ensuring that solutions address the underlying issues rather than merely treating symptoms.

The other choices focus on different aspects of the DMAIC process. Brainstorming potential solutions is a key activity in the Improve phase, while prioritizing customer needs is usually addressed earlier in the Define phase. Finalizing project outcomes is part of the Control phase, where the focus shifts to maintaining the improvements made.
