What is PM, MTTR, MTBF? etc..

Question

Accepted Answer

PM stands for Preventive Maintenance, MTTR is Mean Time To Repair, and MTBF is Mean Time Between Failures.

PM is a proactive maintenance strategy that involves regularly scheduled maintenance to prevent equipment failure.
MTTR is the average time it takes to repair a piece of equipment after a failure.
MTBF is the average time between equipment failures.
These metrics are important for measuring the effectiveness of maintenance programs and identifying areas for improvement.
For example, if the MTTR is high, it may indicate a need for better training or more spare parts.
Similarly, a low MTBF may indicate a need for more frequent maintenance or replacement of equipment.
