CRISC Practice Question: A company has implemented an automated control…
A company has implemented an automated control monitoring system that generates alerts when transactions exceed predefined thresholds. The system has been in production for six months. The risk team notices that the number of alerts has been decreasing, while actual control failures have remained constant. Which of the following is the MOST likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The data feed from transaction systems has degraded, causing missing data
A degraded data feed can cause the monitoring system to miss transaction records, resulting in fewer alerts while actual control failures remain constant. Option A is incorrect: if employees bypass the system, actual failures would likely change, not remain constant. Option B is incorrect: improved control effectiveness would reduce actual failures, which contradicts the given condition. Option D is incorrect: adjusting thresholds to be more restrictive (e.g., higher limits) would reduce alerts but should also reduce actual failures, not keep them constant.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Employees have learned to bypass the monitoring system
Why it's wrong here
Bypassing would lead to more failures, not constant failures.
- ✗
The control effectiveness has improved significantly
Why it's wrong here
If controls improved, actual failures would decrease, but they are constant.
- ✓
The data feed from transaction systems has degraded, causing missing data
Why this is correct
Degraded data reduces input, resulting in fewer alerts despite constant failures.
- ✗
The thresholds were automatically adjusted to be more restrictive
Why it's wrong here
More restrictive thresholds would increase alerts, not decrease them.
