What is MTTR and MTBF?

MTBF, or Mean Time Between Failures, is a metric that concerns the average time elapsed between a failure and the next time it occurs. Whereas the MTTR, or Mean Time To Repair, is the time it takes to run a repair after the occurrence of the failure.

How many hours do you work in a year?

What is MTBF if no failure?

We calculate MTBF by dividing the total running time by the number of failures during a defined period. As such, it is the inverse of the failure rate. MTBF = running time / no. of failures. During normal operating conditions, the chance of failure is random.

How can we calculate MTBF?

To calculate MTBF, divide the total number of operational hours in a period by the number of failures that occurred in that period. MTBF is usually measured in hours.
