DHS Service Contracts: Increased Oversight Needed to Reduce the Risk Associated with Contractors Performing Certain Functions, Report to Congressional Requesters [open pdf - 4MB]
From the Document: "DHS's spending on services--such as guard services and technology support--represents over 75 percent of its annual contract obligations. The Office of Management and Budget has recognized that some service contracts require extra management attention because they pose a risk that the government could lose control of its decisions or operations. GAO [Government Accountability Office] was asked to review DHS's use of and planning for service contracts. This report addresses, among other objectives, the extent to which DHS and selected components and offices use, oversee, and budget for service contracts. GAO analyzed Federal Procurement Data System-Next Generation data from fiscal years 2013 through 2018; selected non-generalizable samples of four components with high service contract obligations and eight service contracts requiring heightened management attention; and interviewed DHS officials."
