CpK and Sigma Level - Need help

Hi Team,

I just learnt that “Cpk and Sigma Level are so closely related that you can find the value of Sigma Level simply by multiplying the value of your Cpk by 3.”

 One of the professors (prior Minitab user) is looking at process capability report from JMP and trying to look for Sigma levels. He is looking at non conformance report and trying to relate to that concept.

Is there a way to reach the corresponding Sigma level value for a Cpk.

Kindly advice

Thanks

Hi @Muralidhara,

I think what you're looking for is the Within/Overall Sigma Z Benchmark option in the Capability Red Triangle.
