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 percentage of recurring incidents is decreasing over time
A decreasing number of recurring incidents indicates that root causes are being identified and resolved, which is a key measure of incident management effectiveness. Option A focuses on resolution speed, which is not the best indicator of effectiveness; Option B may indicate better detection, not effectiveness; Option C is about logging timeliness, which is a process compliance metric, not effectiveness.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The average time to resolve incidents is under 1 hour
Why it's wrong here
Speed is not the same as effectiveness; if root causes are not fixed, incidents recur.
- ✗
The number of incidents reported per month is increasing
Why it's wrong here
An increase may indicate more issues, not effective management.
- ✗
All incidents are logged within 10 minutes of detection
Why it's wrong here
Timely logging is good practice but does not measure the effectiveness of incident resolution.
- ✓
The percentage of recurring incidents is decreasing over time
Why this is correct
A reduction in recurrence shows that the process is identifying and eliminating root causes.
