How are queue lengths calculated?
Queue metrics are essentially occupancy metrics that capture activity within defined service
areas, most commonly the till or cash desk.
In addition to measuring the volume of people entering the area ( entries and
entry rates) and the time they spend there (
Total time and
Average time) we also calculate queue size using two key metrics:
- Average queue length: The average number of people in the queue during the selected time period.
- Maximum queue length: The highest number of people observed in the queue during the selected time period.
These metrics can also be used to measure staff occupancy behind the cash desk (if that area has been defined in your store setup), allowing you to generate actionable insights into the ratio of customers to staff
