What Is MTBF (Mean Time Between Failures)? How to Measure & Improve It

MTBF (Mean Time Between Failures) is a key reliability metric that measures the average time a repairable system runs before failing. It’s crucial for understanding system dependability and predicting potential issues, impacting availability, user experience, and operational costs. While calculated simply as total uptime divided by the number of failures, MTBF is most valuable when tracked as a trend over time and used alongside metrics like MTTR to build more resilient systems through proactive monitoring and preventative maintenance.
