Which item is NOT listed as part of internal oversight mechanisms?

• A. Internal investigation
• B. EWS (Early identification system)
• C. Bureaucratic procedure
• D. External audit

Answer: (D)

Internal oversight mechanisms are controls built into the organization to monitor operations and enforce accountability from within. Internal investigations are conducted by the agency to examine alleged misconduct, and early identification systems flag warning signs before problems escalate. Bureaucratic procedures codify rules and standardize processes to ensure consistent behavior and accountability. An external audit, carried out by an outside party to assess performance and compliance, is not an internal mechanism. Therefore, external audit is the item not listed as part of internal oversight mechanisms.
