b$.$ Suppose management would be happy with three$-$sigma performance. What conclusion to draw from the capability analysis?

Since $C_{pk}$ is the critical value, the process is not capable at the three$-$sigr Since $C_p$ is the critical value, this indicates that the process variability is toc

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

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

B$.$ The specification limits must be revised.

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

D$.$ Nothing. The process is capable.
