WebMTTF: Mean time to failure describes the expected time to failure for a non-repairable system. For example, assume you tested 3 identical systems starting from time 0 until all of them failed. The first system failed at 10 hours, the second failed at 12 hours and the third failed at 13 hours. The MTTF is the average of the three failure times ... WebMTTF (mean time to failure) is a very basic measure of the reliability of non-repairable systems. It represents the length of time a project is expected to continue running until it fails. MTTF is calculated as total business hours divided by the total number of items to be tracked. MTTF is referred to as the life cycle of any product or device.

WebMTBF is the average time elapsed from one failure to the next. MTTR is the average time it takes to repair something after a failure. Meantime to failure is generally used for devices beyond repair. The above: MTTF = 3 years and MTTR = 1 Day. MTBF = MTTF + MTTR = 3 Years + 1 Day = 1095 + 1 = 1096 Days.
