What is the Six Sigma phase that involves visualizing process metrics using charts and diagrams?

In the Improve phase, the primary focus is on developing and implementing solutions to address the root causes identified during the Analyze phase. While metrics may still be reviewed, the emphasis shifts to executing changes rather than visualizing existing data. This phase is about refining processes, not analyzing them.

The Control phase centers on maintaining the improvements made in the previous phases and ensuring that processes remain within desired performance levels. While it may involve monitoring metrics to ensure stability, it does not primarily focus on visualization or analysis of those metrics, which is a key aspect of the Analyze phase.

The Define phase establishes project goals, scope, and objectives but does not involve the visualization of process metrics. Instead, it focuses on identifying the problem, collecting initial data, and understanding customer requirements. Visualizing metrics is not a function of this phase.
