  15. In a traditional inventory system, regularly scheduled deliveries move products from warehouse storage to storerooms until they are needed to stock the shelves. Information Systems Classified by Function

  16. In a just-in-time distribution system, deliveries are smaller and more frequent so that products are only in the storeroom briefly. Information Systems Classified by Function

  17. In a stockless inventory distribution system, deliveries move products from warehouse storage directly to the shelves with no need for a storeroom. Information Systems Classified by Function
