Answer ALL questions in this paper. Read the case article below and answer ALL the questions that follow. UPS and Information Systems Technology Since the start of United Parcel Service in 1907, many things have changed but the promise of the best service and low rates" has stayed the same. Daily, UPS delivers 18.3 million packages around the US and 220 other countries around the world. The question arises; how have they been able to compete with other large carriers such as DHL and FedEx? UPS invests billions each year to upkeep a high level of customer satisfaction all the while keeping its own costs low. One of the biggest parts of their success is owed to the scannable barcode label and the handheld computer, the Delivery Information Acquisition Device or the DIAD, where all the information regarding the package is stored. Anyone sending or expecting a package through UPS can track it online. UPS has created its own information systems to aid in their success. The DIAD and Order Management System or OMS are just mere examples. From optimal routing, to tracking shipments - two day delivery is guaranteed nationwide which in turn helps keep customer satisfaction high while keeping costs low. Just like any other information system, the common security risk experienced at UPS is the phishing attack via email. The cloud computing enables UPS customers to access their service anytime, anywhere that is more efficient to operate their business. It provides the UPS Company with the sharing of information about shipment to customers. Source: https://ovellnikol wordpress.com/2017/09/27/ups-case-study!
