Look at arrivals, waiting, service time, and open lanes in the same minutes before changing the staffing plan.

Put customer arrivals, open counters, service time, and waiting on the same timeline; then adjust coverage for the recurring peak and compare like-for-like trading periods. 01 · Define the metrics ## Read demand and service on one timeline ### Customer demand - Arrivals to the checkout area - Queue length over time - Customers who leave before service ### Waiting and service - Queue entry to service start - Service start to service end - Incomplete waits at observation end ### Available capacity - Active counters or service points - Minutes without coverage - Time from demand threshold to staff response Report the median and a high percentile, not only the average. Keep completed waits, incomplete waits, departures before service, and missing footage separate. 02 · Explain the queue ## Look beyond the length of the line A long line can come from more arrivals, fewer active counters, longer service time, or a layout that makes an open lane hard to reach. Compare those signals in the same minutes. Existing cameras can show visible arrivals, queues, service states, and staff coverage; authorized POS data is required for transaction or sales analysis. - Map the queue. Agree on the entry boundary, service point, and conditions that count as waiting. - Match demand to coverage. Compare arrivals and queue growth with active counter-minutes. - Review the peak. Open the supporting footage to confirm whether the issue is capacity, service duration, or customer routing. 03 · Plan active capacity ## Open capacity when the agreed threshold is met There is no universal lane count. Open enough active capacity to keep the agreed wait-time and queue-length thresholds under control for the observed arrival rate and service-time distribution. Review the decision in short intervals: arrivals, active lanes, completed services, wait percentiles, queue spillover, and the time between a threshold breach and another lane becoming available. Define the trigger before the peak—for example, a queue or wait threshold sustained for an agreed duration—then test it across comparable trading periods. Keep self-checkout, staffed lanes, returns, and specialized service points separate because their service patterns differ. 04 · Evaluate the change ## Compare the same trading conditions Choose comparable weekdays, trading hours, arrival volumes, promotions, and open counters. Change one operating rule—such as the threshold for opening another lane—then compare the wait distribution, departures before service, and uncovered service minutes. Financial ROI requires verified costs and separately authorized transaction outcomes; customer waiting time is not paid labor saved. 05 · Set boundaries ## Choose views that show the full wait They can be evaluated when their approved views show the queue boundary and service state clearly. Validate lighting, occlusion, camera angle, retention, and access before using the result. Fortune AI does not need to infer identity, emotion, or purchase intent for queue measurement, and fitting-room interiors are excluded.
