Your company has just purchased a new machine to cut insoles for the top of the line running shoes. You are excited because the company's goal is no more than 3.4 defects per million, and this machine may be the innovation you need. The insoles cannot be more than 0.001 of a centimeter from the required thickness of 0.250cm (also the mean) and a standard deviation o = 0.0005 centimetres. Determine the Cpk of the new machine. If the process capability of the existing machine is Cpk of 1.0, should a new machine be purchased? Your company has just purchased a new machine to cut insoles for the top of the line running shoes.
