Assignment
Several years after reengineering its production process, ZippyZippy Corporation hired a new controller, Jane SmithJane Smith. She developed an ABC system very similar to the one used by ZippyZippy's chief rival, SouthstreamSouthstream. Part of the reason SmithSmith developed the ABC system was because ZippyZippy's profits had been declining even though the company had shifted its product mix toward the product that had appeared most profitable under the old system. Before adopting the new ABC system, ZippyZippy had used a plantwide overhead rate based on direct labor hours that was developed years ago.

1. Compute the gross profit per wheel if managers rely on the ABC unit cost data.
2. Compute the gross profit per wheel if the managers rely on the plantwide allocation cost data.
3. Which product line is more profitable for ZippyZippy?
4. Why might the controller have expected ABC to pass the cost-benefit test? Were there any warning signs that Zippy'sZippy's old direct-labor-based allocation system was broken?
