JIT Features and Product Costing Accuracy
Prior to installing a JIT system, Buckner Company, a producer of automobile parts, used maintenance hours to assign maintenance costs to its three products (wheels, rims, and ball bearings). The maintenance costs totaled $4,852,960 per year. The maintenance hours used by each product and the quantity of each product produced are as follows:
Maintenance Hours | Quantity Produced | |
Wheels | 198,000 | 173,250 |
Rims | 198,000 | 173,250 |
Bearings | 223,000 | 195,125 |
After installing JIT, three manufacturing cells were created, and cell workers were trained to perform preventive maintenance and minor repairs. A full-time maintenance person was also assigned to each cell. Maintenance costs for the three cells still totaled $4,852,960; however, these costs are now traceable to each cell as follows:
Cell, wheels | $1,392,520 |
Cell, rims | 1,552,320 |
Cell, bearings | 1,908,120 |
