The objective of this audit is to determine whether DoD officials effectively used policies, procedures, and data systems to identify Government Travel Charge Card (GTCC) misuse, abuse, or fraud. Specifically, this audit report is on the effective use of the Visa IntelliLink Compliance Management data mining system (VICM system). According to the General Services Administration SmartPay® statistics, during FY 2023, the DoD GTCC program spent $6.4 billion on 2.3 million open individually billed accounts and 9,416 open centrally billed accounts. The VICM system is a web-based tool which provides the DoD with automated compliance analysis, recordkeeping for all GTCC transactions, and identification and tracking of potential misuse, abuse, and policy violations.
