Frequently asked questions
What is MTTR?
Mean Time to Resolve (MTTR) measures the average time it takes to fully resolve an incident from the moment it is detected. It includes detection, acknowledgement, diagnosis, and remediation. A lower MTTR indicates a more effective incident response process.
What is MTTA?
Mean Time to Acknowledge (MTTA) measures the average time between when an alert fires and when an engineer acknowledges it. MTTA reflects the responsiveness of your on-call team and the effectiveness of your alerting and escalation policies.
What is MTBF?
Mean Time Between Failures (MTBF) measures the average time between the resolution of one incident and the detection of the next. A higher MTBF indicates greater system stability and reliability.
How can I improve MTTR?
To improve MTTR, focus on reducing each phase of the incident lifecycle: set up effective alerting to reduce detection time, implement clear escalation policies to speed up acknowledgement, create runbooks for common issues to accelerate diagnosis, and practice incident response through game days. Automating remediation for known failure modes can also dramatically reduce resolution times.
