Overview: Mean Time to Resolution (MTTR)

Quick Definition

MTTR (mean time to resolve) is the average time it takes to fully resolve a failure. This includes not only the time spent detecting the failure, diagnosing the problem, and repairing the issue, but also the time spent ensuring that the failure won’t happen again.

Mean time to respond is the average time it takes to recover from a product or service failure from the time the first failure alert is received. The difference between the mean time to recovery and mean time to respond gives the time it takes for an alert to come in

As modern organizations increasingly depending on software to run their businesses, these interruptions around MTTR aren't just inconvenient; they endanger the bottom line by potentially disrupting the increasingly important digital customer experience, not to mention adding significant cost, risk, and complexity to the software development process.
