Telecommunications: Agencies Need Better Controls to Achieve Significant Savings on Mobile Devices and Services, Report to Congressional Requesters [open pdf - 15MB]
From the Document: "In 2012, the Office of Management and Budget (OMB) reported that the federal government spent approximately $1.2 billion annually for mobile devices and wireless services with an estimated inventory of about 1.5 million devices. Given that the use of mobile technology in the federal government was expected to increase, OMB identified the potential for achieving efficiencies and reducing spending in this area. At your request, we conducted a study of the federal government's management of mobile devices and services. Our specific objectives were to (1) determine the extent to which federal agencies have developed enterprise-wide inventories of mobile devices and wireless services, and established processes to maintain them; (2) determine the extent to which agencies established effective processes and procedures for monitoring and controlling spending on mobile devices and wireless services; and (3) describe agencies' mobile service rates"
