What’s the difference between MTTA and MTTR?

MTTA and MTTR are both highly relevant response metrics, meaning they measure the response time to a specific event.

MTTA (Mean Time To Acknowledge) tracks the time it takes for your team to acknowledge an incident after it has been detected. We also like to refer to it as Time to First Response in our Engagement Report. “Mean” refers to the average time to acknowledge of all your incidents within a certain period of time.

MTTR (Mean Time To Acknowledge) describes the average time it takes your team to resolve incidents after they pop up. Again, “Mean” describes the average value over all resolved incidents in a certain period of time. As acknowledging an incident is part of the process, improving your MTTA will also improve your MTTR.

Both, MTTA and MTTR are key metrics to track your team’s incident response efficiency. Improving these KPI’s means you are reducing downtime and outages.

All Quiet's Engagement Report automatically tracks these KPI’s for your team and allows to easily analyze details if things went wrong, maximizing your team’s operational resilience over time.
