Data Privacy	100% compliance with NPC mandates	Privacy Impact Assessment (PIA)
Reporting Accuracy	99% accuracy in sample reconciliation	Statistical sampling (n=30)

Acceptance Benchmark: A "Satisfactory" rating requires zero critical findings (High Risk) and fewer than three minor findings.

7. Practical Troubleshooting Scenarios

Scenario 1: Auditee Refusal to Provide Records

Issue: Dept. Head cites "internal policy" to withhold tax documentation from the audit team.
Protocol: Immediately escalate to the Audit Committee. Issue a formal Notice of Impediment. Remind the auditee of their contractual obligation to provide transparency per the internal charter.

Scenario 2: Discrepancy between ERP and Manual Logs

Issue: Financial records in SAP do not match manual petty cash vouchers.
Protocol: Halt testing for that sub-cycle. Perform a 100% full-population reconciliation rather than sampling. Classify as "High Risk" and trigger an immediate investigation by the Loss Prevention Unit.

Scenario 3: Missing Tax Identification Numbers (TIN) on Vendor Invoices

Issue: Failure to meet BIR Revenue Regulation requirements on source documents.
Protocol: Flag the invoice as "Non-Compliant." Issue a memo to the Procurement team to cease payments until valid documentation is secured. Add to the "Watchlist" for future quarterly audits.
