Mean time to first failure

Mean time (to) first failure (MTFF, sometimes MTTFF) is a concept in reliability engineering.

It describes time to failure for non-repairable components like an integrated circuit soldered on a circuit board. For repairable components like a replaceable light bulb the concept of mean time between failures is used to describe the failure rate.
