1) What kind of information is used to compare locations during facilities planning?
2) A p-type control chart shows four consecutive points in a row above the centerline and within zone B. Has an “out of statistical control” condition occurred? Upon what do you base your answer?
3) A Process Performance Measure (PPM) is found to vary nominally with a mean of 105 units and a standard deviation of 5 units. If the specification limits of the PPM are 100 units +/- 20 units, compute the Cp and Cpk of the process. Is this process “capable” of delivering “perfect” quality?
4) How do you know if a process is operating normally (i.e., in statistical control)?
