Reaction Plan Reference number to a reaction plan flow-chart that tells the data-plotter what to do in the event of an out-of-control or out-of-spec. condition. Reaction plans may be somewhat generic for families of process with similar criticality.
Gage Number Reference number for the gage that corresponds to the calibration tracking system.
Sampling Plan How many samples are drawn at what frequency.
Process Stability Is the process in a state of statistical control - Yes or NO.
Cp/Cpk If process is stable, calculate Cp and Cpk.
