DHS Science and Technology: Additional Steps Needed to Ensure Test and Evaluation Requirements Are Met

Description: A letter report issued by the Government Accountability Office with an abstract that begins "In recent years, GAO has reported on challenges the Department of Homeland Security (DHS) has faced in effectively managing major acquisitions, including programs which were deployed before appropriate testing and evaluation (T&E) was completed. In 2009 and 2010 respectively, DHS issued new T&E and acquisition directives to address these challenges. Under these directives, DHS Science and Technology Directorate's (S&T) Test & Evaluation and Standards Office (TES) is responsible for overseeing T&E of DHS major acquisition programs--that is, those with over $300 million in life-cycle costs--to ensure that T&E and certain acquisitions requirements are met. GAO was asked to identify (1) the extent to which TES oversees T&E of major acquisitions; and (2) what challenges, if any, TES officials report facing in overseeing T&E across DHS components. GAO reviewed DHS directives and test plans, interviewed DHS officials, and reviewed T&E documentation from a sample of 11 major acquisition programs from each of 11 different DHS components. The results of the sample cannot be generalized to all DHS programs, but provided insights."
