SOLUTIONS TO CRITICAL THINKING CASES
CASE 18.1
SHOULDN'T WE DO THINGS DIFFERENTLY?
30 Minutes, Strong
Mr. Brown:
Thank you for your recent memo. I am glad to see that you have become familiar with our cost
accounting methods and have constructive suggestions. You are correct that we could use job
order costing and, also, that we could base our unit cost computations upon equivalent units,
rather than upon units completed. But let me explain briefly why we are currently doing what
we do.
Given that we have a substantial amount of work in process in our fermenting tanks, you may
ask, Why? The answer is that we always have the same quantity of beer in our fermenting
tanks. As the amount of our work in process does not change from month to month, our
productive effort is essentially equivalent to the amount of finished product coming off our
bottling line.
