Mean time to repair (MTTR) is a metric used by maintenance departments to measure the average time needed to determine the cause of and fix failed equipment. It is a basic technical measure of the maintainability of equipment and repairable parts. MTBF can be calculated by dividing the total uptime by the total number of breakdowns. Overview Mean time to repair or recover (MTR), also abbreviated as MTTR, is a metric that is used to assess maintenance effectiveness. To do so, you could track open tickets, unresolved issues, total work hours per project, and other productivity measures. MTTR (mean time to repair) is the average time required to fix a failed component or device and return it to production status. The goal of any organization should be to decrease MTTR and increase the MTBF of a system. Indeed, although issues are being resolved, it seems your critical systems are offline more often than not. Global Standards Mean Time to Repair (MTTR) The mean time to repair is given by .

Die Mean Time To Repair (MTTR) wird als die mittlere Zeitspanne zur Wiederherstellung nach einem Ausfall eines Systems definiert. Mean Time to Repair (or MTTR) measures the average amount of time it takes to go from an incident report initially being filed to the incident being resolved and marked closed. Generally, mean time to repair indicates efficiency in correcting processes, and mean time between failures indicates the reliability of a system. Note 1 to entry: The MART is the expected effective time to repair c, (see Figure 5, Figure 6 and Figure 7). Mean Time to Repair is a measure of how long it takes to get a product or subsystem up and running after a failure. Traditionally, customer impacting events have been measured by the mean-time-to-repair (MTTR). It is measured from the point of failure to the moment the system returns to production. The average may be broken down by platform, service or application. Mean Time To Repair (MTTR) refers to the amount of time required to repair a system and restore it to full functionality. 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. the formula for which is: This takes the downtime of the system and divides it by the number of failures. Next, divide the figure by the total number of repairs made during the same period. If the MTTR is high, that information can lead to improvement changes within the organization. To give you an MTTR definition; MTTR is one of many service-related KPIs, but it is perhaps the easiest way to gain a quick perspective on how effectively your IT department is providing resolution. It is a basic technical measure of the maintainability of equipment and repairable parts. 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. Using this up-to-date information, an organization can establish its MTTR and MTBF, allowing engineers to run preventative maintenance and to plan for repairs before a failure occurs. What Is Mean Time to Repair? MTTR (mean time to repair) is the average time required to fix a failed component or device and return it to production status. MTTF -- mean time to failure -- predicts the failure rate for products that cannot be repaired. Mean Time to Repair is generally defined through the following equation: Mean time to repair (MTTR) MTBF and MTTF measure time in relation to failure, but the mean time to repair (MTTR) measures something else entirely:how long it will take to get a failed product running again. These lapses of time can be calculated by using a formula. Sadly, operators don’t get to pick the nature of service issues and dedicating more resources isn’t an option.
