Which phase in Six Sigma is primarily about analyzing data?

The phase in Six Sigma that is primarily about analyzing data is the Analyze phase. During this phase, the team closely examines the data collected during the Measure phase to identify the root causes of defects or problems within the process. This step involves various statistical analyses and tools to understand patterns, correlations, and relationships among different variables affecting the process.

By thoroughly analyzing the data, teams can uncover insights that are crucial for informed decision-making in subsequent phases. The main goal here is to determine what factors are contributing to issues, which in turn helps to formulate effective solutions in the Improve phase. Therefore, the Analyze phase is crucial for developing a solid understanding of the problem before moving forward with improvement efforts.
