Generally, mean time to repair indicates efficiency in correcting processes, and mean time between failures indicates the reliability of a system. auch Mean Time To Repair (abgekürzt jeweils MTTR) wird als die mittlere Reparaturzeit nach einem Ausfall eines Systems definiert. Next, divide the figure by the total number of repairs made during the same period. Normalerweise betrachtet man es als die Durchschnittszeit, während der etwas funktioniert, bis es ausfällt und wieder repariert werden muss. MTTR (mean time to repair) is the average time it takes to repair a system (usually technical or mechanical). They reached this time over 10 separate incidents. The measure doesn’t include just repairing the issue but also accounts for time spent testing. While MTTR calculates the time it takes to make a repair following a failure, MTBF -- mean time between failures -- refers to the average time between one failure and the next. If the total time required to fix the issue is 120 minutes, and four breakdowns caused that downtime, an organization can conclude that a breakdown will take approximately 30 minutes to repair.

MTBF, or Mean Time Between Failures, is a metric that concerns the average time elapsed between a failure and the next time it occurs. The Mean Time to Repair is a measurement of the maintainability of equipment and repairable parts. This includes repair time, testing period, and return to the normal operating condition. MTTR, MTBF and MTTF can also be tracked by software that issues reports detailing failure rates and repair cycles for individual products. Maintenance time is defined as the time between the start of the incident and the moment the system is returned to production (i.e. The goal of any organization should be to decrease MTTR and increase the MTBF of a system. In organizational management, mean down time (MDT) is the average time that a system is non-operational.
