Re: Are these examples of stable systems with points outside the control limits?



Richard,

The purpose of a control chart is to gain insight into the process.

What is the process you are investigating?

Is it possible to take measurements rather than counting defects in your
process?   Defects relate to the specification more than the process itself.
