What Is Mean Time to Acknowledge?
Mean time to acknowledge (MTTA) is the average delay from when an alert is raised to when a responder acknowledges it and takes ownership. It isolates the human-response portion of an incident timeline, separate from detection or repair. A rising MTTA can signal alert fatigue, paging gaps, or understaffed rotations.
Why it matters
Fast detection is wasted if no one responds promptly. MTTA exposes that handoff gap, helping teams tune escalation and paging so alerts are picked up quickly.
