PROCESS DRIFT AN EXAMPLE OF SUBSTANCE OF PAPER AS CTP
Process CTP Measured by Operator A Over a Period of Time – Day 1
The Same CTP Measured By Operator C Over Same Period Of Time the Same Day
Same CTP Measured By Operator A on the 2nd Day Over The Same Period Of Time
The Same CTP Measured on 2nd Day By Operator B Over Same Time
The Same CTP Measured Over The Same Period Of Time on 2nd Day
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.
