UPS relies heavily on information technology and systems to track packages, route deliveries efficiently, and provide customers with visibility and services. The inputs to UPS's package tracking system include package and customer details. Data is processed through handheld devices, scanners, and mainframe computers to track packages and access information worldwide. Key technologies like DIAD devices, scanning, wireless networks, and software for tracking, billing, and logistics management support UPS's business strategy of high customer service and low operational costs. Without these information systems, UPS would not be able to compete effectively, maintain service levels, or leverage data and technology to continuously improve operations.
