The document summarizes a case study on UPS's use of information technology to compete globally. It discusses UPS's package tracking system which takes in package data, collects customer signatures and pickup/delivery times using a DIAD device. This data is transmitted to UPS's central network for storage and global access by customers to track packages. Key technologies used are barcoding, DIAD devices, and network infrastructure. These technologies help UPS achieve its business strategy of providing high quality service at low prices by automating package tracking. The systems provide value by allowing both UPS and customers to always know a package's location, which would be difficult and more expensive without this technology. If the technologies were not available, package tracking would be harder for UPS employees
