Topic: Process Capability Problem 1 The specification limits of a certain quality characteristics are 10010 units. A process being considered for producing this product has a variance of 9 units. A. WHAT can you say (quantitatively) about the process capability? B. Suppose that the process average shifts to 91 units. CALCULATE the process quality level in terms of the Part/Million (PPM). C. What is the percentage of increase or decrease in the number of nonconforming items due to the shift Note: you can use the PPM table available on the sheet of the Formulas and Tables for both Cp and Cpk
