control. The times to complete the transactions were measured. process standard deviation to be 3.29 (days) for use in the process capability analysis. The lower and upper specification limits (in days) for the mortgage process times were 4 and 18. a. Calculate the process capability index and the process capability ratio values. The process capability index Cpk= (Enter your response rounded to three decimal places.) The process capability ratio Cp= (Enter your response rounded to three decimal places.) b. Suppose management would be happy with three-sigma performance. What conclusions is management likely to draw from the capability analysis? Since Cpk is the critical value, the process capable at the three-sigma level. Since Cp is the critical value, this indicates that c. What remedial actions, if any, do you suggest that management take? A. Management should use a lower target process capability ratio. B. The variability of the process must be greatly reduced. C. The specification limits must be revised. D. Nothing. The process is capable
