a. Calculate the process capability index and the process capability ratio values. The process capability index Cpk=0.404. (Enfer your response rounded to throe decimat places.) The process capabilify ratio Cp=0.5152, (Entor your response rounded to throe decimal places.) b. Suppose management would be happy with three-sigma performance What conclusions is manogement 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 octions, if any, do you supgest thnt management take? A. The specification limits must be revised. B. Management thould use a lower target process capabily ratio. C. The variability of the process must be greatly reduced. D. Nothing The process in capable. The MoGranger Mortgage Company is imterested in monitoring the performance of the mortgage process. Fitteen sarnples of five completed martgage transactions each were faluen during a period when the process was believed to be in control. The times to camplete the transactions wore measured The McGranger Mortgage Company made some changes to the procens and undertook a process capabiity study. The following data were obtained for 15 samples of size 5 . Based on the individual observations, management estimated the process standard dovition to be 4.03 (days) for wse in the process capablity analysis The lower and upper specification limits (in dayb) for the mortgage process times were 4 and 21. a. Calculate the procest capabarty index and the procese capablity rato values The process capability index Cpx= (Enter your rosporse founded to throe decimal places.)
