A letter report issued by the General Accounting Office with an abstract that begins "More small businesses are turning to subcontracting as a way to participate in the federal government's $250 billion procurement program. DOD, accounting for about two-thirds of federal procurements, has a critical role in providing opportunities to small businesses through subcontracting programs such as the Test Program for Negotiation of Comprehensive Small Business Subcontracting Plans (Test Program). In addition, Congress raised concerns about the potential for small businesses to lose opportunities to firms performing work outside of the United States. GAO was asked to review (1) DOD's assessment of the Test Program's effectiveness, (2) the performance of contractors participating in the Test Program, (3) the Defense Contract Management Agency's (DCMA) oversight of contractors' small business subcontracting efforts, and (4) the extent and reasons contractors are subcontracting with businesses performing outside the U.S."
