Practice question: An engineering consulting firm for a small business has designed the production capacity for Jay's Truck Wash to be 50 trucks per day. But due to the truck wash requiring some manual human focused work to hand-dry trucks once they leave the wash cycle, the system capacity is actually 40 trucks per day. However, Jay has noticed a decline in his profits over the past 3 months because the anecdotal data shows on average the business is only seeing 36 cars per day. 1. What is the efficiency and utilization of Jay's truck wash business? 2. If Jay has 2 people drying cars, working 7.5hours each per day - what is their productivity? 3. If Jay wants to increase the productivity of his two staff to 3 trucks, how efficient will this make his business? Is this productivity achievable?
