United Parcel Service (UPS) utilizes advanced information technology systems, such as the Delivery Information Acquisition Device (DIAD) and a web-based Order Management System (OMS), to enhance efficiency and reduce costs while delivering over 15.6 million packages daily. These systems enable optimal routing strategies, real-time shipment tracking, and improved customer service, all aimed at providing 'best service and lowest rates.' If these information systems were unavailable, customer satisfaction would decline, global operations would suffer, and operational efficiencies would be lost.
