How do audits verify the effectiveness of control measures?

• A. They check procurement records and vendor performance.
• B. They interview staff without observing operations.
• C. They check implementation, functioning, and resulting risk reduction; identify gaps and recommend improvements.
• D. They focus solely on incident counts.

Answer: (B)

Audits verify the effectiveness of control measures by assessing how well a control is actually working in practice, not just whether it exists on paper. The focus is on implementation, the way the control operates during real operations, and whether its use leads to a measurable reduction in risk. This means examining evidence of how the control is put into action, observing operations, testing the control through sampling or re-performance, and reviewing relevant records to see if the intended risk reduction is achieved. From this, auditors identify gaps between design and operation and then propose concrete improvements to strengthen the control environment. Relying solely on interviews without observing processes or on incident counts misses how controls perform day to day and how they contribute to overall risk reduction.
