Just In Time (JIT) is a production strategy that aims to reduce waste and improve efficiency by receiving goods only as they are needed in the manufacturing process. This approach minimizes inventory costs and ensures that materials are fresh and relevant, allowing companies to respond quickly to customer demands. The JIT system relies on strong relationships with suppliers and precise scheduling. By coordinating deliveries closely with production schedules, businesses can maintain a streamlined operation. This method is widely used in industries such as automotive manufacturing, where companies like Toyota have successfully implemented JIT to enhance productivity and reduce excess inventory.
