Since $C_{pk}$ is the critical value, the process is not capable at the three$-$sigma level.

Since $C_p$ is the critical value, this indicates that the process variability is too large

c$.$ What remedial actions, if any, do you suggest that management take?

A$.$ Management should use a lower target process capability ratio.

B$.$ The specification limits must be revised.

C$.$ The variability of the process must be greatly reduced.

D$.$ Nothing. The process is capable.
