QUESTION 22 (10 points) - Cost of Quality and Pareto Chart Following are data on cost of quality at an automobile manufacturing plant for last year: Components under assembly product quality program ID Cost ($M) Type Assembly-line worker training programs Inspection specialist training programs Testers training programs Design and purchase of quality inspection tools 01 0.5 ? 02 0.3 ? 03 0.3 ? 04 0.4 ? Regular maintenance & recalibration of precision instruments 05 0.2 ? Regular maintenance & recalibration of manufacturing tools 06 0.1 ? Scheduled overhaul of critical machines 07 0.7 ? Inspections of intermediate steps 08 0.2 ? Final-product testing programs 09 0.1 ? Returning repairs and reworks (including warranties) 10 0.7 ? Voluntary-recall repairs and reworks 11 0.5 ? Re-testing of repairs and remakes due to returns & recalls 12 0.4 ? Assembly-line downtime due to step errors or breakdowns 13 0.3 ? Reworks due to production errors 14 0.3 ? Scrap (including labor and parts) 15 0.3 ? Supplier rating and incentive programs 16 0.2 ? Random tests on critical components at arrival 17 0.1 ? Quality planning and improvement initiatives 18 0.2 ? (a)[3] Classify these data into 4 types according to the cost-of-quality model (P/A/I/E). (b)[3] Calculate the totals of those 4 cost types and draw the corresponding Pareto diagram. (c) [2] Based on part (b), describe and interpret the results. (d) [2] Based on part (c), make some managerial recommendation(s). 2 QUESTION 22 (10 points) - Cost of Quality and Pareto Chart Following are data on cost of quality at an automobile manufacturing plant for last year: Components under assembly product quality program ID Cost ($M) Type Assembly-line worker training programs Inspection specialist training programs Testers training programs Design and purchase of quality inspection tools 01 0.5 ? 02 0.3 ? 03 0.3 ? 04 0.4 ?
