Delivery Schedule Adherence (DSA)
Definition
Delivery Schedule adherence (DSA) is a business metric used to calculate the timeliness of deliveries from suppliers. Delivery schedule adherence is calculated by dividing the number of “on time” deliveries in a period by the total number of deliveries made. The result is then multiplied by 100 and expressed as a percentage.
