Also referred to as the “finishing schedule” as it may include other operations than simply the final operation, and also may be used for environments where there is no assembly but only filling, packaging, painting, etc. It is a schedule of end items either to replenish finished goods inventory or to finish a make-to-order product. For make-to-order products, it is prepared after receipt of a customer order, is constrained by the availability of material and capacity, and it schedules the operations required to complete the product from the level where it is stocked (or master scheduled) to the end item level.
