Another very useful analysis option during the control phase and beyond is provided by a control chart. This enables you to identify at a glance whether or not the existing process fluctuations are staying within set limits. It represents the average, maximum and minimum value of a process graphically.
To do this, create a control diagram for the process cycle time as described in chapter Evaluating PPM data in Minitab®.
Procedure
A control chart is displayed based on your settings.
See also chapter Assign a Minitab® macro to the PPM analysis.
You can then use the favorite to easily start the Minitab® evaluation again from PPM.
