A fundamental difference between the Q and P systems is the length of time needed for stockout protection. The P system needs stockout protection only during the lead time because orders can be placed as soon as they are needed and will be received $L$ periods later. The Q system, however, needs stockout protection for the longer $P+L$ protection interval because orders are placed only at fixed intervals, and the inventory is not checked until the next designated review time.
