Key Maintenance Metrics to Track

There are numerous maintenance metrics that can be tracked, but focusing on a few key indicators is essential for getting started. Here are some of the most important metrics to consider:

Mean Time Between Failures (MTBF)

MTBF measures the average time between failures of a repairable system or component. A higher MTBF indicates greater reliability. The formula for calculating MTBF is: Total Uptime / Number of Failures. For example, if a machine operates for 1000 hours and experiences 2 failures, the MTBF is 500 hours.

Mean Time To Repair (MTTR)

MTTR measures the average time required to repair a failed system or component. A lower MTTR indicates more efficient maintenance processes. The formula for calculating MTTR is: Total Repair Time / Number of Repairs. For example, if it takes 4 hours to complete 2 repairs, the MTTR is 2 hours.

Overall Equipment Effectiveness (OEE)

OEE is a comprehensive metric that measures the overall performance of a piece of equipment or a production line. It takes into account availability, performance, and quality. The formula for calculating OEE is: Availability x Performance x Quality. A higher OEE indicates better overall equipment performance.

Preventive Maintenance Compliance (PMC)

PMC measures the percentage of planned preventive maintenance tasks that are completed on time. A higher PMC indicates a more proactive maintenance approach. The formula for calculating PMC is: (Number of PM Tasks Completed On Time / Total Number of PM Tasks Scheduled) x 100%.

[Maintenance Cost](/learn/definitions/maintenance-cost) as a Percentage of Revenue

This metric shows how much of your revenue is being spent on maintenance. It helps you understand the cost-effectiveness of your maintenance program. Calculated as: (Total Maintenance Costs / Total Revenue) x 100%.

It's crucial to select the metrics that are most relevant to your specific industry and business objectives. Regularly review and adjust your metric selection as your needs evolve.

Calculating and Interpreting Maintenance Metrics

Once you've selected the key maintenance metrics you want to track, the next step is to accurately calculate and interpret them.
