Assessing and tracking all compliance audit findings is the best way to support the effectiveness of a compliance program. This allows an organization to identify areas of non-compliance, take corrective action, and monitor improvements over time12. While implementing an awareness plan, using a governance, risk, and compliance (GRC) tool, and monitoring applicable regulations can contribute to a compliance program, they do not provide the same level of continuous improvement and effectiveness as assessing and tracking audit findings.
