In operations, it is the time between the actual processes. The main aim of a company is to minimize the waiting time between the processes. At times, waiting time depends on how important a process is. This will tell how fast the request will be serviced or which request will be serviced first in case of multiple requests. The customer behaviour varies depending on the waiting time for a service. Eg – There maybe balking customers who may not join a queue due to its length. Or customers maybe reneging, leaving the queue after some time without taking the service.
Eg – Jobs waiting for their turn to be processes in a CNC machine. Here waiting time for a job in queue is the time taken for the job in front to be loaded, machined and removed from a CNC machine
Vehicles waiting at the toll plaza to get a toll receipt. Here waiting time for a vehicle in queue is the time for the vehicle in front to reach the poll booth, obtain the receipt and leave.
