How Can Brands Measure On-Time Delivery Performance Across Suppliers?

Measure on-time delivery as the share of due orders or shipments that meet an agreed promised event and date.

Define whether that event is factory readiness, carrier handover, port departure, or warehouse receipt; these are not interchangeable. Establish consistent rules for partial quantities, revised dates, and buyer-caused holds. Compare suppliers using the same definitions, and review delay causes alongside the headline percentage to identify actionable improvements.
