1)What caused the existing system at ETO to fail?
This system was based on the assumption that direct costs and overhead are consumed in the same proportion for all product testing. However, this is not the case and therefore the system failed. For example, due to the implementation of the vendor certification and the just-in-time delivery, some products are already tested and do not need any further tests, and ETO faces a decreasing number of the tests performed. On the other hand, new components require more high technology tests. They consume highly automated equipment and require different testing procedures compared to other products.

2)Calculate the reported costs of the five components using: a.The existing system
With a burden rate of 145%:
Burdenproduct = Direct Labourproduct x Burden Rate (in this case, 145%) Total costsproduct = Direct Labourproduct + Burdenproduct

b.The system proposed by the accounting manager

The accountant proposes a division into machine hour and direct labor burden. According to Exhibit 5, the new burden rate is 21% and the machine hour rate is $80,10. Burdenproduct = Direct Labourproduct x Burden Rate (in this case 21%) Machine Burdenproduct = Machine Hourproduct x Machine Hour Rate (in this case $80,10) ProductDirect LabourBurdenMachine HourMachine BurdenTotal Costs ICA91719318,514822591

c.The system proposed by the consultant

The consultant proposes a three-burden-pool system, treating the main test room and mechanical test room as different cost pools. According to Exhibit 5, the costs would be: •For the main test room burden rate: 2.103.116/ 33.201 = $63.34 •For the mechanical test room burden rate: 1.926.263/...
