Appendix B – Profitability Analysis
App B-2
3. A catering service has contracts with a number of customers to supply lunches on a daily
basis. The chef has complained of the long hours she must work to prepare all of these
lunches and has threatened to quit. It would be very difficult, if not impossible, to replace the
chef. To reduce the pressure on the chef, some contracts may have to be cancelled. (The
catering service can cancel any contract with seven days notice.) To help make this decision,
the profitability of each customer should be measured by dividing the daily incremental profit
from serving each customer by the amount of the time it takes the chef each day to prepare the
customer’s meals.
4. The profitability index for a volume trade-off decision involving products should be
computed by dividing the fully allocated cost of a product by the amount of the constrained
resource required by one unit of the product.
5. A company that makes horsehair cowboy belts cannot meet the demand for belts due to a
limited supply of artisans who know how to make the belts. To determine which models of
the cowboy belts should be emphasized, the company should rank the models by the amount
of time an artisan requires to make the model.
