The Western center has a new order-processing system. You want to determine whether the new system decreases the time that is needed to prepare an order. The center also has two different packing procedures. You want to determine which procedure is more efficient. You decide to perform a factorial experiment to test which combination of factors enables the shortest time that is needed to prepare an order for shipment. You can use this data to demonstrate Analyze Factorial Design, as in Chapter 5 of Getting Started for Minitab Statistical Software.
A team at the shipping center in the western region collects data to find the best combination of order-processing system and packing procedure.
