With so much technology at their fingertips, customers now want and expect complete visibility of their mail, from entry to delivery. The Intelligent Mail barcode (IMb) program has helped to bring total visibility closer to reality, and other technologies, such as radio frequency identification (RFID) and global positioning system (GPS) tracking, can fill the gaps. Complete visibility of mail provides real-time information about mail to customers and the U.S. Postal Service, including service performance data. This visibility into mailing activities allows the Postal Service to better manage its operations, increase route efficiency, improve service, and control costs. Mail visibility gives customers insight into mailing activities and provides them analytics to drive business decisions. As the IMb program matures and more customers adopt the full service offering, the Postal Service gets closer to total visibility of mail. But gaps in end-to-end visibility still exist, such as when mail travels on contracted highway route transportation and it is no longer “communicating” its location. One solution is to use GPS on HCR trucks to have visibility of mail during transport. In November 2010, the Postal Service initiated a limited-scope GPS program on about 900 of its 15,500 commercially contracted highway transportation routes, which covers about 300 highway contract route (HCR) suppliers. The suppliers were supposed to provide certain GPS tracking information every 30 minutes while hauling mail, including location of the vehicle. However, a recent OIG audit found that this GPS program was capturing only limited data, primarily because suppliers were not consistently reporting the data to the Postal Service. Limited data resulted in reports that were not useful for managing highway transportation routes. Still, the audit found enormous potential in this GPS program. If the Postal Service expanded it and data were captured and reported properly, it would provide the Postal Service with actionable reports that could include enhanced data analytics, real-time alerts, and fuel analysis and route optimization information. GPS data-based reports could be indicators of efficiency improvements, as well as potentially fraudulent activity. Further, the Postal Service could integrate this GPS program with its other mail visibility technologies, such as IMb and the surface visibility program, to enhance total mail visibility, which the Postal Service has cited as a priority and “essential to transforming the business.” The key, however, would be to ensure adequate supplier compliance. Further, integration of the various visibility programs would have to be seamless and cost-effective. What would be the best way to integrate the various visibility technologies? Would extending the GPS program to more surface transportation routes be a logical next step? Are there other technologies that should be considered to close some of the visibility gaps?
