To determine process capability it is important that the process is in statistical control. It is meaningless to characterize a process that is unpredictable.
The worksheet is open and shows the data we used in the process control tutorial.
The data is filtered to only the phase when the process was-in control is used.
The 6-up capability analysis shows the process control charts, a histogram of the distribution, a box-plot summary of the distribution, a mean +/- 3 sigma plot, and normal probability plot. Upper and lower specification limits show the specification.
