that is missing only one item on one line is considered to be incomplete. It is also common for companies to track specifically the number of stockouts encountered and number of back orders generated during a time period as indicators of availability.
Operational performance deals with time and is typically measured by average order cycle time, consistency of order cycle time, and/or on-time deliveries. Average order cycle time is typically computed as the average number of days, or other units of time, elapsed between order receipt and delivery to customers. Order cycle consistency is measured over a large number of order cycles and compares actual with planned performance For example, suppose average order cycle time is five days. If 20 percent were completed in two days and 30 percent in eight days, there is great inconsistency around the average. in situations where delivery dates or times are specified by customers, the most stringent measure of order cycle capability is on-time delivery, the percentage of times the customers delivery requirement are actually met.
