Question

Quizplus · Accepted Answer

The average length of time before failure of a product or component is generally referred to as Mean Time to Failure (MTTF). This is different from Mean Time Between Failures (MTBF), which includes not only the time it takes for a product or component to fail, but also the time it takes to repair or replace it. Failure rate and reliability are related concepts, but not exactly the same as MTTF. Average time to failure is not a commonly used term.
