How to Evaluate Acceptable MTBF?

Acceptable MTBF evaluator uses Acceptable MTBF = 1/Probability of Synchronizer Failure to evaluate the Acceptable MTBF, The Acceptable MTBF is a measure of the average time that a system, component, or device operates without failure. It's commonly used to quantify the reliability of a system. A higher MTBF indicates better reliability. Acceptable MTBF is denoted by MTBF symbol.

How to evaluate Acceptable MTBF using this online evaluator? To use this online evaluator for Acceptable MTBF, enter Probability of Synchronizer Failure (P_fail) and hit the calculate button.
