Maintenance metrics are quantitative measures used to assess the performance and effectiveness of maintenance activities within an organization. These metrics help track key aspects such as equipment reliability, downtime, and maintenance costs, enabling businesses to identify areas for improvement and optimize their maintenance strategies. Common maintenance metrics include Mean Time Between Failures (MTBF), which measures the average time between equipment breakdowns, and Mean Time to Repair (MTTR), which indicates the average time taken to fix a malfunction. By analyzing these metrics, organizations can enhance operational efficiency and reduce overall maintenance expenses.
