The document discusses Just-In-Time (JIT), an inventory strategy developed in Japan after World War II. JIT aims to increase efficiency and reduce costs by receiving goods only as needed in the production process, keeping stock levels minimal. Toyota was the first to successfully implement JIT in the 1970s. The key aspects of JIT are receiving stocks just before production and maintaining close supplier relationships, with no production occurring without a customer order. Major benefits of JIT include reduced costs from less tied-up capital and storage space.
