On October 5, 2008, Department of Defense Acting Inspector Gordon S. Heddell established the Office of Professional Responsibility (OPR) to provide a system of checks and balances that will assist him in leading and managing the organization in the most effective manner possible.  

The new office reports directly to the Acting Inspector General and is responsible for conducting system reviews and analysis of each DoD IG component to determine managerial, operational, and administrative efficiency and effectiveness. This will be accomplished primarily by conducting periodic inspections of headquarters, regional, and field offices. OPR will also be responsible for conducting independent objective professional investigations into allegations of employee misconduct.

OPR is staffed by a multidisciplinary team of auditors, analysts, administrators, and special agents.
