MTTR
metricMean time to resolve, restore, recover or repair, depending on who is defining it. In incident management it usually means the average time from detection to service restoration. MTTR measures how fast service comes back, not whether the cause is understood, which is why an organisation can have a good MTTR and still repeat the same outage monthly.
