Maintenance indicators are the vital signs of a maintenance department.

They provide the data necessary to move from a 'gut feeling' management style to a data-driven strategy.

Tracking these Key Performance Indicators (KPIs) is essential for identifying areas for improvement and demonstrating the value of maintenance to the overall business.

Key indicators are typically grouped into categories: - **Reliability KPIs:** Mean Time Between Failures (MTBF) is the most common, measuring how often equipment fails.

- **Availability KPIs:** Uptime and Availability percentages show how often an asset is ready to work when needed.

- **Reactive Work KPIs:** Mean Time To Repair (MTTR) measures how quickly the team can fix a breakdown.

The percentage of planned vs.

unplanned maintenance is also critical.

- **Cost KPIs:** Tracking maintenance cost as a percentage of the asset's replacement value, or cost per mile/hour, helps control budgets.

- **Compliance KPIs:** Ensuring that the percentage of on-time preventive maintenance tasks is high.

By monitoring these indicators, managers can objectively assess performance, justify investments in new tools or strategies, and ultimately drive the optimization of their entire maintenance process.
