What does MTTA mean?
MTTA (Mean Time to Acknowledge) is a metric that measures a company's response time to any incidents (failures, alarms, complaints, etc.). The lower the MTTA, the faster problems that occur are detected and can therefore be resolved more quickly.
How to calculate the MTTA?
The MTTA is calculated by dividing the total response time required to acknowledge all incidents by the number of incidents that occurred in a given time period.
In one week, there were 12 incidents. The response time to all 12 incidents was 7 hours (420 minutes).
420/12 = 35
The MTTA for this week was therefore 35 minutes.
