Owens Ltd. produces specially machined parts. The parts are produced in batches in one continuous manufacturing process. Each part is custom produced and requires special engineering design activity (based on customer specifications). Once the design is completed, the equipment can be set up for batch production.Once the batch is completed, a sample is taken and inspected to see if the parts are within the tolerances allowed. Thus, the manufacturing process has four activities: engineering, setups, machining, and inspecting.In addition, there is a sustaining process with two activities: providing utilities (plantwide) and providing space. Costs have been assigned to each activity using direct tracing and resource drivers:Engineering 2,000,000; Setups 600,000; Machining 1,500,000; Inspection 700,000; Providing space 300,000; Providing utilities 200,000.Activity cost drivers for each activity have been identified and their practical capacities listed:Machine hours 30,000; Setups 1,000; Engineering hours 5,000; Inspection hours 2,500; The costs of facility-level activities are assigned using machine hours.The only one cost pool that is a unit-level cost is
