"The Department of Homeland Security's (DHS) Secure Border Initiative Network (SBInet) is to place surveillance systems along our nation's borders and provide Border Patrol command centers with the imagery and related tools and information needed to detect breaches and make agent deployment decisions. To deliver SBInet, DHS has relied heavily on its prime contractor. Because of the importance of effective contractor management and oversight to SBInet, GAO was asked to determine the extent to which DHS (1) defined and implemented effective controls for managing and overseeing the prime contractor and (2) effectively monitored the contractor's progress in meeting cost and schedule expectations. To do this, GAO analyzed key program documentation against relevant guidance and best practices, and interviewed program officials. "
