According to the document:
“The Department of Defense and Central Intelligence Agency conducted a joint inspection of the National Reconnaissance Office (NRO) from October through December 1995. The goal of the inspection was to determine the efficiency and effectiveness of the processes and mechanisms to manage and administer NRO resources and administrative programs. The objectives to: evaluate the authorities and delegations of thc NRO and oversight organizations; evaluate the processes to identify mission requirements and plan and organize resources for them; evaluate internal administrative and management programs; and, evaluate internal management oversight processes.”
I requested the document under the Freedom of Information Act (FOIA) in June of 2016, and it was finally released in April of 2018.
Note: Strangely, the letter erred on multiple dates. It said the date of the letter was April 27, 2017, but was actually sent the same day in 2018. It also notes my request was from 2006, but actually, it was 2016. Unclear why the mistakes, but alas, I wanted to point them out for clarity.
