Common measures of system performance

I don’t understand this Management question and need help to study.

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.
