We evaluated the Defense Intelligence Agency’s (DIA’s) efforts to assess, standardize, and coordinate open source intelligence (OSINT) tools and data sets across the Department of Defense Components. This included DIA’s role in standardizing tools and data sets and the Agency’s internal coordination efforts. We identified deficiencies in DIA’s ability to meet its responsibilities and issued nine recommendations. Our findings and recommendations provide our assessment and insight to Agency decision makers to use as they address risk gaps relating to our FY 2021 DIA Top Management Challenge—Leadership Controls and Oversight. Management agreed with our recommendations.
