How do you calculate MTTR?

MTTR is calculated using the formula: MTTR = Total Resolution Time / Number of Incidents. For example, if you had 5 incidents with total resolution time of 10 hours, your MTTR would be 2 hours (120 minutes).

What is a good MTTR benchmark?

Industry benchmarks vary, but generally: Excellent teams have MTTR under 30 minutes (top 10%), Good teams are under 1 hour (top 25%), Average teams are under 2 hours (top 50%). High-performing organizations like Google and Amazon target single-digit minute MTTRs for critical services.

What's the difference between MTTR and MTTA?

MTTR (Mean Time To Resolution) measures the total time to fully resolve an incident. MTTA (Mean Time To Acknowledge) measures only the time from detection to when someone acknowledges the incident. MTTA is typically much shorter and measures response speed, while MTTR measures total resolution effectiveness.

How can I reduce my team's MTTR?

Key strategies to reduce MTTR include: 1) Implement automated alerting and monitoring, 2) Create runbooks for common incidents, 3) Use a single communication channel during incidents, 4) Practice incident response through regular drills, 5) Conduct blameless post-mortems to learn from each incident.

Q: What is MTTR (Mean Time To Resolution)?

MTTR (Mean Time To Resolution) is the average time it takes to fully resolve an incident from the moment it's detected. It's calculated by dividing the total resolution time of all incidents by the number of incidents. MTTR is a key SRE and DevOps metric for measuring incident response effectiveness.

What is MTTR?

Mean Time To Resolution (MTTR) is the north-star metric for incident response teams. It measures the average time it takes to fully resolve an incident from detection to service recovery.

At Runframe, we believe MTTR isn't just about speed—it's about operational maturity. Teams with low MTTR typically have better automation, clearer runbooks, and superior communication.

The Formula

MTTR = Σ Durations / n

Sum of all incident resolution durations divided by the total number of incidents in a specific period.
