Why it Matters ?
Reduces average repair times for customer satisfaction.
In-depth Use Case / Real-world Example
MTTR is calculated by dividing the total downtime from repairs by the number of repair incidents. For example, if a machine has been down for 100 hours over 5 incidents, the MTTR would be 20 hours. This KPI is crucial for measuring service efficiency. In manufacturing, reducing MTTR is vital to minimize production downtime and maintain operational efficiency. A lower MTTR indicates a faster, more effective response to failures.
