Nylle Ltd uses a job-costing system at its Melbourne furniture plant. The plant has a Machining Department and an Assembly Department. Its job-costing system has two direct cost categories (direct materials and direct manufacturing labour) and two manufacturing overhead cost pools (the Machining Department overhead, allocated to jobs based on actual machine-hours, and the Assembly Department overhead, allocated to jobs based on actual direct manufacturing labour costs).
