Attraction Corporation 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 $1,000,000 Setups 900,000 Machining 2,000,000 Inspection 800,000 Providing space 250,000 Providing utilities 180,000 Activity drivers for each activity have been identified and their practical capacities listed: Machine hours 25,000 Setups 200 Engineering hours 5,000 Inspection hours 2,500 The costs of facility-level activities are assigned using machine hours. What is (are) the product-level activity(ies)? a.engineering b.inspecting c.setups d.All of these choices are correct.
