13. CONCLUSIONS One can look at the Process Variation
over a same period of time on the same day by different operators.
by the same operator at different periods of time on different days.
This is called Process Drift, which can provide an approximate estimate of how well the process is centered towards its target.
One can stabilize the process by taking corrective actions for special cause variations visiting the process by process standardization & standard operating procedures.
