The following check sheet was constructed on 45 defective motors identified during a final inspection process in a small electronics plant.

a. Construct a Pareto chart for these data.
b. Problems appear to deserve the most attention? Why?.
c. Assume that high leakage and low output at low and high speeds is 5 times as severe as high turn on speed, and that a dead unit or bad voltage set point is 10 times as critical as high turn on speed. Also assume that high turn-on speeds, high ripple current, and a bad regulator are all of equal importance. Construct a weighted Pareto chart and describe how your recommendations would change from your conclusions in part b.
