Marathon Electric India Interview Questions and Answers

Cp and Cpk are statistical process capability indices used in FMEA to measure the ability of a process to produce products within specifications.

• Cp measures the potential capability of a process to produce products within specifications, assuming the process is centered at the mean.

• Cpk measures the actual capability of a process to produce products within specifications, taking into account the process mean and variation.

• Cpk is a more accurate measure of process capability th...read more
