  • MTBF, MTTR, MTTF, MTTA: Understanding incident metrics

    2021-12-17 · MTBF is a metric for failures in repairable systems. For failures that require system replacement, typically people use the term MTTF (mean time to failure). For example, think of a car engine. When calculating the time between unscheduled engine maintenance, you''d use MTBF—mean time between failures.
