5. Percentage of Total Product Cost 1960–1990 Direct Labor Materials Overhead 1960 Percentage Change 1990 Source: National Association of Accountants. Traditional Cost Systems Evolved in an Era Significantly Different From Today’s Business Environment. b Direct labor as a percentage of total cost has dropped by half b Greater diversification in product lines and customer segments. b Data collection and processing costs have plummeted b Decreasing correlation between direct labor usage and overhead consumption

6. TRADITIONAL COST ACCOUNTING ASSIGNS OVERHEAD BASED ON THE NUMBER OF UNITS PRODUCED, OR THE NUMBER OF MACHINING HOURS, OR LABOR HOURS USED TO PRODUCE AN ITEM. ASSUMES THERE IS A RELATIONSHIP BETWEEN OVERHEAD AND VOLUME MEASURES. USUALLY FUNCTIONALLY ORIENTED. TCA WORKS BEST FOR SIMPLE PRODUCTS, WITH SIMILAR VOLUMES, WITH SIMILAR DIRECT LABOR CONTENT.

7. ACTIVITY BASED COSTING A METHOD OF ASSIGNING COSTS TO PRODUCTS, BASED ON ASSIGNING THE COSTS OF RESOURCES USED BY THE REQUIRED TO MAKE THE PRODUCT – REGARDLESS OF WHERE THE COSTS WERE INCURRED A METHOD OF ASSIGNING COSTS TO PRODUCTS, BASED ON ASSIGNING THE COSTS OF RESOURCES USED BY THE ACTIVITIES REQUIRED TO MAKE THE PRODUCT – REGARDLESS OF WHERE THE COSTS WERE INCURRED
