A local garbage disposal company increased its profitability even though it reduced its prices in order to attract new customers. This was made possible through the use of automated trucks, thereby reducing the number of workers needed per truck. The company also switched from a concentration on household hauling to a concentration on commercial hauling. As a result of its experience, company management planned to replace all their old trucks and increase the overall size of the truck fleet, doubling hauling capacity.

Demand for garbage removal services would increase in the future.

Doubling of capacity would not cause bottlenecks, leading to a decrease in productivity.

Commercial clients have more potential than household customers.
