You are working as a quality improvement engineer at a firm (ABC) that produces plastic gears for small motors, such as those in hand tools and appliances (e.g., electric screwdrivers and blenders). The primary customer for the gears is ACME Manufacturing. Recently, ACME has been complaining to your sales staff of late delivery of trucks containing ABC gears. ACME has monitored and examined their production process by recording truck delivery time, as shown in the table below. In the past, ACME states that trucks were rarely exceeding eight (8) days for delivery. Truck # 1 2 3 4 5 6 7 88 9 10 11 12 13 Delivery Time 5 10 6 6 7 8 7 8 9 5 9 6 6 Truck # 14 15 16 17 18 19 20 21 22 23 24 25 26 Delivery Time 5 8 8 9 7 9 6 10 5 6 7 8 6 Truck # 27 28 29 30 31 32 33 34 35 Delivery Time 8 7 9 7 10 8 7 7 8 Questions 1. ACME wants to show the variation in delivery time. Select and plot the delivery time data on the most appropriate quality management tool. (Hint: consider classes of delivery days, such as 0-3, 4-6, 7-9, etc.) 2. Does ACME have a valid compliant? (You will need to report the percentage of late deliveries.)
