Delivery Delay Histogram

This histogram groups late parcel deliveries by the number of hours past their promised arrival time. Most late parcels fall in the first two hours, and the frequency drops as delays become longer. That pattern helps an operations team separate a common small delay from a smaller group of severe exceptions. Use the same promise-time definition across all records and exclude canceled deliveries unless they are part of the question. The chart does not explain why parcels were late, so pair it with route, carrier, weather, and warehouse data when diagnosing causes. Keep the bins consistent when comparing different weeks or service regions.
