Essay

Prior to installing a JIT system, Plasticize Company used machine hours to assign maintenance costs to its three products of 3-inch, 5-inch, and 7-inch plastic tubing.
The maintenance costs totaled $120,000 per year. The machine hours used by each product and the quantity produced of each product are as follows:
After installing JIT, three manufacturing cells were created and the cell workers were trained to perform maintenance. Maintenance costs for the three cells still totaled $120,000; however, these costs are now traceable to each cell.
Required:
a. Compute the maintenance cost per roll for each type of tubing before JIT is installed.
b. Compute the maintenance cost per roll for each type of tubing after JIT is installed.
c. Explain why the JIT maintenance cost per roll is more accurate than the cost per roll using the traditional approach.
