There are several different ways to measure the effectiveness of your major incident management procedures and solutions, but which is the most important indicator of success? Different measures will tell you different things about how you are doing and where you can improve.
This article explores the essential metrics you need to know and why one, in particular, should be the North Star for your incident response strategy.
Major incident management: Key metrics
Before diving into the debate between response and mitigation, let's establish the foundational metrics that track an incident from alert to resolution.
What is MTTD? (Mean Time to Detect)
Mean Time to Detect measures the interval between the moment an incident begins and the moment your team becomes aware of it. High MTTD usually indicates a gap in your monitoring and observability tools. If you can’t see the fire, you can’t put it out.
What is MTTA? (Mean Time to Acknowledge)
Mean Time to Acknowledge is the time it takes from an alert being triggered to a human or automated system "claiming" the issue. It’s a measure of responsiveness and team availability.
What is MTTR? (Mean Time to Respond/Repair/Recover/Resolve)
MTTR is the most commonly referenced metric for major incident management, but it is also the most prone to confusion. Depending on who you ask, the "R" can stand for:
- Respond: The average time it takes to recover from a product or system failure.
- Repair: How long it takes to fix the technical fault, not including logistics.
- Recovery: How quickly you can get the system back up and running.
- Resolution: How long it takes to close the ticket entirely, with the technical issue fully resolved.
What is MTTM? (Mean Time to Mitigate)
This is where the focus of many organizational leaders is shifting. Mean Time to Mitigate measures how quickly you can stop the "bleeding" for the customer.
Unlike resolution, which implies the underlying bug has been fully resolved, mitigation is about restoring service. If a bank's mobile app is down due to a memory leak, mitigation might involve failing over to a secondary region. The bug still exists, but the customer can once again access their funds.
MTTR vs. MTTM: What are the key differences?
The distinction between these two is more than just semantics; it’s a difference in philosophy.
Which metrics really matter for continuous improvement in major incident management?
While all metrics are important indications of the effectiveness of your response, MTTM is the most accurate reflection of customer impact. In the enterprise world, this is often measured in "Bad Customer Minutes."
If a cyber incident or a major system failure occurs, prevention has already failed. At that point, the only thing that matters is the delta between the start of the outage and the restoration of service. Experienced leaders drive their teams to reduce MTTM because it prioritizes the human experience over the technical "cleanliness" of the fix.
According to Cutover CEO Ky Nichol, "Customers don't care when you fix the bug — they care when you stop the bleeding; that's why MTTM can focus the mind more than MTTR.”
Resolution can happen in the calm of the following day; mitigation must happen now.
