As the process stabilizes, Cp and Cpk will give better readings as new results are compared to older studies. My next step will be to calculate Cp and Cpk with a larger number of samples and make sure the measuring instrument used to size to inspect the wire is not giving a false reading. In this situation, I only used 34 samples and was not sure if the process was reliable. If Cpk is under 1.33, it is advised that changes may need to be made to the process. 61 and more than half of what it should be. The Cpk is a more relied-upon variable and will be lower than Cp.Since this result is less than one, we would consider the process unstable.
