Chess you plan to evaluate two suppliers A and B on a weighted score. The weights De (out of 10) are assigned in the following table Computed the weighted score for appliers Write in words which supplier would you prefer?

You are a purchaser and a quality management expert. A manufacturer of different automobile products received an order to supply 2,500 shafts 4 inches long and 2 inch- diameter which are driving shafts and fit into ball bearings. The tolerance for the diameter of the shaft is +0.006 inches. It is the shaft-diameter that you need to check for quality assurance. From a sample of shafts produced by your supplier, you computed that the mean and standard deviation of the production process for shaft diameter are 2 inches and 0.0025 inches, respectively. To produce the shaft of within the tolerance limit is not only important but essential because a smaller diameter shaft will be loose in the bearing, and larger diameter shaft will not fit in the bearing Based on your expertise, does the production process meet the Six Sigma requirements? (10) b. What should be the maximum standard deviation of the production process to meet the Six- Sigma quality requirements? (10) 2
