Consider the following diagram: What is the highlighted area of the diagram known as?

The Rule of Seven is a statistical process control concept stating that a run of seven consecutive data points on one side of the centerline indicates an assignable cause rather than random variation. This pattern is highlighted in control charts to alert quality managers that the process has likely shifted and is no longer in statistical control. It is a standard tool in project quality management for identifying trends before they become critical defects.

A control point is a defined threshold or inspection gate in a process workflow, not the name for a pattern of consecutive data points on a control chart.

A control chart is the full diagram used to track process performance over time, not the term for the specific highlighted region of consecutive points within it.

Six Sigma is a broad quality improvement methodology aimed at reducing defects to 3.4 per million opportunities, not a label for any specific highlighted area on a control chart.
