INCORRECT
Another valuable metric typically provided is the mean time to repair
(MTTR), which describes the average amount of time it will take to
get the device fixed and back online.

CORRECT
Another valuable metric typically provided is the mean time between
failures (MTBF), which describes the amount of time that elapses
between one failure and the next. Mathematically, this is the sum of
mean time to failure (MTTF) and MTTR, which is the total time required
to get the device fixed and back online.
