5. Mean Time Between Failures = (Total up time) / (number of breakdowns) "Mean Time" means, statistically, the average time. "Mean Time Between Failures" is literally the average time elapsed from one failure to the next. Usually people think of it as the average time that something works until it fails and needs to be repaired (again). "Mean Time To Repair (MTTR)" is the average time that it takes to repair something after a failure. For something that cannot be repaired, the correct term is "Mean Time To Failure" (MTTF). Some would define MTBF – for repair-able devices – as the sum of MTTF plus MTTR. In other words, the mean time between failures is the time from one failure to another.
