How is customer delivery on time (cDOT) calculated?

Customer delivery on time (cDOT) is calculated by taking half the total delivery trip time and adding half the age of the order. This formula accounts for both the time taken to deliver the order as well as the age of the order itself, providing a comprehensive view of the delivery performance. By incorporating both elements, cDOT reflects how timely the delivery was relative to when the order was placed, which is crucial for assessing customer satisfaction.

Using just the total delivery trip time or the average delivery time for all orders does not consider the specific context of each individual order, nor does it factor in how long the customer has been waiting. Therefore, the combination of total delivery time and order age offers a more nuanced metric for evaluating delivery efficacy.
