Exercise 11.11 External Linkages, Customer Costing, Customer Profitability Emery Company sells small machine parts to heavy equipment manufacturers for an average price of $1.05 per part. There are two types of customers: those who place small, frequent orders and those who place larger, less frequent orders. Each time an order is placed and processed, a setup is required. Scheduling is also needed to coordinate the many different orders that come in and place demands on the plant's manufacturing resources. Emery also inspects a sample of the products each time a batch is produced to ensure that the customer's specifications have been met. Inspection takes essentially the same time regardless of the type of part being produced Emery's Cost Accounting Department has provided the following budgeted data for customer- related activities and costs (the amounts expected for the coming year): Frequently Ordering Customers Less Frequently Ordering Customers Sales orders Average order size Number of setups Scheduling hours Inspections Average unit cost* This cost does not include the cost of the following "customer-related" activities 21,000 2,100 26,250 36,750 26,250 2,100 21,000 5,250 5,250 5,250 $0.56 Customer-related activity costs: Processing sales orders Scheduling production Setting up equipment Inspecting batches S 2,310,000 1,260,000 3,780,000 5,040,000 $12,390,000 Total Required: 1.
