Any evaluation of network operations tooling ends up asking whether it made incidents shorter or quieter. These metrics suit any NOC, including MSPs. Answering honestly requires definitions agreed before the measurement starts, and enough context that the numbers cannot be misread.
Why a single MTTR misleads
An average resolution time blends very different events: a quick reboot and a multi-day carrier repair. A few long incidents dominate the mean. It also mixes stages that different tools affect differently. Report the median and a high percentile, and segment by incident type, so improvement in one category is not hidden by another.
Break the lifecycle into stages
- Time to detect: from the fault occurring to the first signal a person or system could act on
- Time to acknowledge: from alert to a responsible engineer taking ownership
- Time to diagnose: from acknowledgement to an evidence-supported cause
- Time to resolve: from diagnosis to confirmed recovery
- Time to verify: from the fix to proof that dependent services are healthy
Measure noise directly
Track how many raw alerts, notifications or tickets are produced per distinct incident. State the counting method: what counts as one alert, and over what window. A lower ratio is only good if independent faults are still reported separately, so pair it with a false-correlation check.
Measure the mistakes
- False correlation: unrelated faults merged into one incident
- Missed incidents: real faults with no incident raised
- Wrong or unsupported diagnosis: causes proven incorrect on review
- Reopened incidents: marked resolved and then recurred
Capture diagnostic effort, not only elapsed time
Ask engineers how many tools or devices they consulted and whether the evidence they needed was already attached to the incident. A short elapsed time can hide heavy manual work, and a long one can hide waiting on a carrier.
Get a baseline first
Measure the current process for a defined period before changing anything, using the same definitions you will use afterward. Without a baseline, improvement claims are anecdotes.
What not to claim
- A universal percentage reduction that applies to every network
- Results from a lab or simulation presented as field performance
- Improvement without stating the sample size, period and exclusions
