In supply chain management and transportation planning, the last mile or last kilometer is the last leg of a journey comprising the movement of passengers and goods from a transportation hub to a final destination. The concept of "last mile" was adopted from the telecommunications industry, which faced difficulty connecting individual homes to the main telecommunications network. Similarly, in supply chain management, last-mile describes the logistical challenges at the last phase of transportation getting people and packages from hubs to their final destinations.
