(independent and identically distributed) and follow an exponential distribution. These include the arrival process, the service and departure process, the number of servers, the queuing discipline (such as first-in, first-out), the queue capacity, and the size of the client population. This important data could be fed back into staff schedules for better staff allocations in order to make them more efficient for the customer needs. When looking at the queuing situation of a printer, the customers are the requests that have been sent to the printer, and the server is the printer.

Queuing theory plays an important rule mathematically and qualitatively in calculating the best efficient way of delivering required services under variable conditions. The end result is a set of conclusions that aim to identify any flaws in the system and suggest how they can be ameliorated. The reason such express lanes exist is that grocery stores using queuing theory have found that customer satisfaction is improved by enabling customers who are only buying a few things to check out more quickly, as opposed to having to wait in line behind other customers with full carts of groceries.
