The objectives of this type of audit are to determine whether financial transactions are related to an agency's programs, are reasonable, and are recorded properly in the accounting systems. This type of audit may also focus on specific performance issues. Where appropriate, these engagements may also provide economy and efficiency comments. Audits are selected using a risk-based approach. Larger departments are audited on a divisional, agency, or program basis rather than on a department-wide basis because of their size and complexity.
