I am pleased to present the Defense Intelligence Agency (DIA) Office of the Inspector General (OIG) semiannual report (SAR) to the U.S. Congress for the reporting period April 1, 2018, through September 30, 2018. This summary of accomplishments is reported in accordance with the Inspector General (IG) Act of 1978, as amended. This year marks the 8th year since we became a statutory IG— marking the 8th anniversary of our SAR—and coincides with the 40th anniversary of the IG Act.
Our professional staff of auditors, inspectors, and investigators continues to provide relevant and timely oversight to detect and deter fraud, waste, and abuse and protect the integrity and effectiveness of DIA programs. Within this period, our Audits Division completed an audit of DIA's unliquidated obligations where we found the Agency was unlikely to spend $250 million of its FY 2017 appropriations due in part to lack of proper monitoring of full use of funds throughout the purchase order lifecycle and deobligation timeliness. Inspections highlights include an evaluation of DIA's human capital services determining the need for a comprehensive human capital strategy; an evaluation of human intelligence (HUMINT) collection operations management identifying successful integration efforts with a few opportunities to improve; and an evaluation of the Defense Intelligence Analysis Program (DIAP), which identified areas to improve DIAP integration, management, and automation. Our Inspections Division also evaluated DIA information security practices under the Federal Information Security Modernization Act (FISMA), which identified areas for improving the overall information security posture. Finally, we concluded an evaluation of the Agency Whistleblower program where we issued five recommendations including a need to strengthen program management and inclusion of all Presidential Policy Directive 19 requirements.
I would also like to highlight our team's increased collaboration with Agency officials. As a result of persistent dialogue with management, we strengthened coordination efforts to better inform management of our intent and to meet the expectations of our issued recommendations. This increase in collaboration led to the closure of 21 recommendations by our Audits and Inspections teams this period. Because of this, we can dedicate more work hours to the eight announced audits and inspections we are currently working that include topics such as counterintelligence, cyber, IT services contracts, and the annual financial statements. Not to be excluded, our Investigations Division opened 19 cases and closed 23, and has 68 ongoing investigations.
In closing, I thank our OIG team members for their enduring focus and quality contributions to the work outlined in this report. I would also like to recognize the collaboration and support of DIA managers at all levels, without which we would not be able to perform our mission in a timely, independent, and objective manner. Finally, I thank Congress and the DIA Director for their lasting commitment to supporting the important work of our office.
