Many businesses utilize waiting lines to manage customer service. For example, banks, amusement parks, supermarket checkouts, fast food restaurants, call centers, check-in counters at airports, emergency departments of hospitals, and so many more. In the course of your week, consider an experience you had that led to a temporary demand for service that exceeded capacity, for example, variation in service duration or arrival rates, which led to a waiting line. Explain common measures of system performance and which of the common measures may be useful for the business where you experienced a waiting line. Detail why that measure would be useful, and develop a strategy to minimize the waiting line while minimizing cost. Develop a calculation to aid the business in making their operational choices.
