what is on time delivery

On-time delivery is a performance indicator measuring the rate of deliveries made on time. On-time delivery is the No. 1 performance figure everyone tracks. The definition of on-time delivery can vary among shippers based on their performance criteria. Some shippers are very specific and consider arriving a minute early or a minute late not on time, while others have a more generalized idea and consider the shipment on time as long as it arrives on the specified day.
