MTTR

MTTR is an abbreviation that has several different expansions, with greatly differing meanings. It is wise to spell out exactly what is meant by the use of this abbreviation, rather than assuming the reader will know which is being assumed. The M can stand for any of minimum, mean or maximum, and the R can stand for any of recovery, repair, respond, or restore. The mean is also subject to interpretation, as there are many different ways in which a mean can be calculated, so the method to be used should also be made explicit.
