P - CHARTSPC (Statistical Process Control) A process which uses
control charts to evaluate whether any part of the production
process is out of control.
Control charts are graphs that reflect a visual diagram to see
if sample products remain inside of their control limits.
Control charts have two main functionsEstablish control limits
for the processMonitor whether the production process is outside of
these control.
When both occurrence and non occurrence can be measured, P chart
is used.
Assumption While the sample size gets larger, the proportion of
defects can be placed into a normal distribution curve
