Mean Time to Repair (MTTR)
MTTR (Mean Time to Repair) Definition
Mean Time to Repair (MTTR) describes the average time required to repair a defective system, device or technical component after a failure. It is an important indicator of the efficiency of repair processes in IT, production, technology and service.
Mean Time to Repair is often confused with Mean Time to Recovery, which is also abbreviated as MTTR. However, Mean Time to Recovery refers to the total time of the failure from the detection of the malfunction to the resumption of operation, while Mean Time to Repair specifically refers to the repair itself.

MTTR calculation & formula
MTTR begins at the moment repair work commences and ends when functionality has been successfully restored. A low MTTR therefore means that faults are rectified quickly, processes are up and running again, and downtime is minimised.
The formula for calculating the mean time to repair is:
MTTR = total duration of all repairs / number of repair operations

Mean Time to Repair vs. Mean Time to Recovery
Although mean time to repair is often the go-to metric for many companies, mean time to recovery might be more important, especially when it comes to the total response and recovery time after a disruption or incident.
| Term | Focus |
|---|---|
| Mean Time to Repair | Pure repair time, once work has begun |
| Mean Time to Recovery | Total time from the occurrence of the fault to recovery, including detection, alerting, coordination, repair and completion |
For companies with critical processes (e.g. in production, IT, energy, transport), mean time to recovery is an equally relevant metric because it reflects the overall recovery behaviour – and therefore goes beyond technical remediation.

How safeREACH helps optimise MTTR
safeREACH is a platform for digital alerting and structured crisis communication. It does not assist with the repair itself, but with everything that needs to happen before and during the repair to minimise repair times – and, above all, to speed up the entire recovery process.
Features such as:
- Automatic alerting of technical teams
- Escalations in case of non-response
- Standardised processes & checklists
- Real-time transparency
... ensure that failures are detected immediately, the right people are reached quickly and measures are implemented effectively.
The result:
- Faster initial response
- Shorter coordination times
- Less downtime between alert and repair start
- And thus: a lower MTTR and a significantly optimised mean time to recovery

MTTR as a central KPI in production facilities
Mean time to repair is a key metric for measuring the efficiency of technical service and maintenance processes. Reducing MTTR saves time, costs and resources while increasing the reliability and availability of systems.
Solutions such as safeREACH enable repair measures to be initiated more quickly, processes to be made more efficient and escalations to be avoided – a decisive lever for companies that want to actively optimise the time it takes to resume regular operations.
