Just-In-Time (JIT) Delivery is a supply chain management philosophy and practice which reduces the costs of inventory by shipping goods in response to actual customer demand, rather than having products pre-stocked and waiting for customers. In this way, JIT Delivery helps companies reduce their costs by using fewer resources for production, warehousing, and delivery of items. By utilizing an efficient and reliable supply chain, companies are able to ensure that the right products get to their customers on time and at the right cost. This approach allows them to gain a competitive advantage in the markets they serve.
