The Audits specialty is responsible for conducting independent and objective audits of DIA operations. Audits provide essential accountability and transparency over Government programs and enable decision makers to improve operations, reduce costs, comply with laws and regulations, and strengthen internal controls to reduce the potential for fraud and illegal acts. The OIG initiates audits based on legal requirements, risk assessments and input from legislators, oversight bodies, DIA leadership and officers, and the public. DIA OIG auditors generally conduct two types of audits: performance and financial statement audits. Audits cover a wide range of topics, and require auditors to develop general auditing skills including data gathering, analysis and critical thinking, as well as subject matter expertise in areas such as contracting, information technology and financial statement audits.

The Inspections specialty is responsible for evaluating, inspecting and promoting the efficiency and effectiveness of DIA organizations, programs and functions, and provides OIG with a flexible and effective mechanism for oversight and review of programs by using a multi-disciplinary staff and multiple methods for gathering and analyzing data. The division accomplishes this responsibility by conducting in-depth reviews across the Agency that examine and assess processes, procedures, internal controls, performance measures, compliance with regulatory and policy guidance, interrelationships and customer satisfaction. All evaluations and inspections are conducted in accordance with quality standards for inspections established by the Council of Inspectors General for Integrity and Efficiency.

Forensic auditors serve as team members in support of fraud, waste and abuse investigations. Forensic auditors establish investigative plans to document investigative activity in the performance of data analytics to detect fraud, waste and abuse, including the use of data visualization and creating statistical models for fraud detection. Using data analytical skills, forensic auditors ensure data quality, perform data cleaning and track data alignment to support investigative findings and recommendations. Working in concert with the OIG Counsel, they sort through data ambiguity to ensure investigative alignment with administrative findings and Federal criminal code violations.
