How does an investigation differ from an audit or an inspection?
The Office of Investigations conducts investigations of criminal, civil, and administrative misconduct related to organizational programs and operations. Investigations examine specific allegations, reports, or other information indicating possible violations of law or regulation. Investigations conducted by OIG criminal investigators usually are the result of allegations received from Department or agency management or employees, other OIG units, Inspectors General of other agencies, the Congress, or the public. As necessary, the assistance of auditors, inspectors, and other experts may be enlisted in investigative operations. OIG conducts investigations according to investigative procedures established by the professional community, which include reviews of relevant files and documentation and interviews with and written statements from complainants, witnesses, technical experts, and subjects of inquiries.
