摘 要：In recent years, nearly half of all annual apprehensions of illegal entrants along the southwest border have occurred along the Arizona border. Under the Secure Border Initiative Network (SBI net ), CBP deployed surveillance systems along 53 of the 387 miles of the Arizona border with Mexico. After DHS canceled further SBI net procurements, CBP developed the Plan, which includes a mix of radars, sensors, and cameras to help provide security for the remainder of Arizona's border. GAO was asked to review the status of DHS's efforts to implement the Plan. This report addresses the extent to which CBP (1) developed schedules and Life-cycle Cost Estimates for the Plan in accordance with best practices, (2) followed aspects of DHS's acquisition management guidance in managing the Plan's programs, and (3) identified mission benefits and developed performance metrics for surveillance technologies to be deployed under the Plan. GAO reviewed schedule, cost, and acquisition documents and analyzed fiscal year 2010 through June 2013 data on apprehensions and seizures.
