DIFOT

Delivered In Full and On Time (DIFOT), a standard for measuring delivery performance in a supply chain. Some consider this standard superior to other delivery performance indicators, such as shipped-on-time (SOT) and on-time performance (OTP), because it focuses on deliveries primarily from the point of view of the customer, rather than from the view of the supplier. DIFOT attempts to measure how often customers get what they want when they want it.
