MTTR (Mean Time To Repair) and MTBF (Mean Time Between Failures) are core reliability KPIs used to measure maintenance efficiency and machine reliability in manufacturing and asset-intensive operations.
How MTTR & MTBF Are Tracked
Breakdown Recording
- Automatic (PLC / IoT) or manual entry
- Start time (failure)
- End time (machine running)
Work Order Linkage
- Breakdown work order created
- Technician start & end time logged
- Spare parts & actions recorded
System Calculation
- CMMS auto-calculates MTTR & MTBF
- Machine-wise, line-wise, plant-wise view
What Good Values Indicate
| KPI | Improving Trend Means |
| MTTR ↓ | Faster repair & response |
| MTBF ↑ | Better machine reliability |
Benefits
- Reduced downtime
- Data-driven maintenance planning
- Improved OEE & productivity
- Better asset lifecycle decisions
