Decision Case 18-1 Harris Systems specializes in servers for workgroup, e-commerce, and ERP applications. The company’s original job costing system has two direct cost categories: direct materials and direct labor. Overhead is allocated to jobs at the single rate of $22 per direct labor hour. A task force headed by Harris’s CFO recently designed an ABC system with four activities. The ABC system retains the current system’s two direct cost categories. Overhead costs are reflected in the four activities. Pertinent data follow:
