Why it Matters ?

Reduces repair times for increased availability.

In-depth Use Case / Real-world Example

MTTR is calculated by dividing total repair time by the number of breakdowns. For instance, if a machine takes 10 hours to repair after 5 breakdowns, MTTR is 2 hours. Lower MTTR is an indication of efficient repair processes and quick response times. Minimizing MTTR helps reduce production downtime, increases machine availability, and lowers the overall impact on manufacturing operations. This can be achieved through effective maintenance strategies, spare parts inventory management, and well-trained technicians.
