(MTTRは平均復旧時間(Mean Time To Recovery)や平均解決時間(Mean Time To Resolve/Resolution)を意味することもあります。) 平均障害間隔または平均故障間隔(MTBF:Mean Time Between Failures):デバイスやシステムの障害が1度発生してから次に発生するまでの平均稼働時間。システムやコンポーネントの...
MTBF is a measure of how long a system or product is expected to operate before it fails, and it is used to plan for maintenance or replacement. MTTR is a measure of how long it takes to repair a system or product after it fails, and it is used to minimize downtime and reduce repa...
Unsure about the differences between MTTR, MTTD, MTTF, MTBF and other incident KPIs are? Learn terms, meanings, and how each is calculated!
Low-MTTRassets takeless timeto service and are considered highly maintainable. Alternatively, assets withhigh MTTRvalues typically indicate room for improvement. MTTR and MTBF MTTRis often used alongsideMean Time Between Failures(MTBF)to measure the availability and reliability of assets.MTBFrefers to ...
Total elapsed time from initial failure to the reinitiating of system status. Mean Time To Restore includes Mean Time To Repair (MTBF + MTTR = 1.) What is Root Cause Failure Analysis (RCFA)? A technique for uncovering the cause of a failure by deductive reasoning down to the physical and...
What is MTBF? Mean time between failure (MTBF) is a measure of the reliability of a system or component. It’s a crucial element of maintenance management, representing the average time that a system or component will operate before it fails. The MTBF formula is often used in the ...
MTBF represents the time duration between a component failure of the system. Similarly, organizations may also evaluate theMean Time To Repair (MTTR), a metric that represents the time duration to repair a failed system component such that the overall system is available as per the agreed SLA ...
To further simplify, MTBF is a key reliability metric for systems that can be repaired or restored and MTTF is the expected time to failure of a system. To calculate MTBF, you need MTTF and MTTR values. Let’s look at an example. ...

MTTR is another metric whose acronym can lead to some confusion. Like MTBF, it is used to assess repairable equipment. Maintenance professionals calculate MTTR by dividing the time they spend repairing an asset by the total number of repairs performed. Why...
