A metal fabricator produces connecting rods with an outer diameter that has a 1 ± .01 inch specification. A machine operator takes several sample measurements over time and determines the sample mean outer diameter to be 1.002 inches with a standard deviation of.003 inch 1) Calculate the process capability index for this example. Does the current process achieve 3- sigma quality? 2) Without changing the specification limits, can you propose two different ways to improve the process capability such that it can achieve 3-sigma quality?
