(Q2) ETO’s manager picked up 5 components to evaluate the impact of different accounting system.
The reported costs from existing system can be computed as follows, given the burden rate 145%:
Product Direct Labor Burden Total Costs
ICA 917 1,330 2,247
ICB 2,051 2,974 5,025
Capacitor 1,094 1,586 2,680
Amplifier 525 761 1,286
Diode 519 753 1,272
Based on the accounting manger’s proposal, the operation burden can be divided into machine-hour and direct labor burden. We use the revised burden rate 21% and machine-hour rate $80.1 to show the updated costs:

If ETO follows the consultant’s recommend, treats the main test room and mechanical test room as different cost pools. The three-burden-pool system reports the cost: ($63.34 for main room burden rate and $112.63 for mechanical room)

Among the three costing systems, we prefer the consultant’s proposal (Q3). The accounting manager treats the machine hours as separate cost pool because the automated operation process leads to large percentage of total cost comparing to direct labor. Measuring the machine hour costs can help us to assess the total burden more accurate. However, given the same machine hours, the different hours
