Homeland Security Acquisitions: Opportunities Exist to Further Improve DHS's Oversight of Test and Evaluation Activities, Report to Congressional Requesters [open pdf - 5MB]
From the Highlights: "DHS invests several billion dollars in major acquisition programs each year to support its many missions. Conducting T&E [test and evaluation] of program capabilities is a critical aspect of DHS's acquisition process to ensure systems work as intended before being delivered to end users, such as Border Patrol agents. GAO [Government Accountability Office] was asked to review DHS's T&E activities for major acquisition programs. This report examines, among other objectives, the extent to which DHS has (1) assessed programs' test results and used this information to make acquisition decisions; (2) policies and guidance that reflect key T&E practices; and (3) a workforce to effectively oversee programs' T&E activities."
