MTTR, MTBF, MTTA & MTTF - Metrics, examples, challenges, and tips
When your system crashes at 3 AM and customers start flooding your support channels, every minute feels like an eternity. Mean Time to Repair (MTTR) measures exactly how long these painful moments last and more importantly, how you can make them shorter. MTTR tracks the average time between when a failure occurs and when your system is fully operational again. This metric directly impacts customer satisfaction, revenue, and your team's sanity during incident response.
