View global indicators for maintenance and availability performance


Mar 01, 2007

When a company wants to compare maintenance and availability performance internally or externally, they need a common platform in terms of predefined indicators so that they can compare apples to apples. This challenge is being met by the SMRP (Society for Maintenance & Reliability Professionals) and the EFNMS (European Federation of National Maintenance Societies). These two maintenance organizations have launched a joint activity to compare and document existing indicators for maintenance and reliability performance. This will help the maintenance manager to understand the indicators and the definitions for the indicators.

SMRP has defined a number of Best Practice Metrics to measure maintenance performance. The process is ongoing, and metrics are publicly available at In 2000, EFNMS defined a set of indicators to measure maintenance performance (see These indicators are now incorporated in the European standard prEN 15341 “Maintenance Key Performance Indicators.”

The comparison activity is now aiming at a documentation of the similarities and the differences in the SMRP metrics and the prEN 15341 standard.

With the increased globalization and with companies acting globally, the need for a common understanding of the indicators to measure maintenance and availability performance is paramount, and there is no doubt that this activity in a short period of time will play a part in a global standard for maintenance indicators. This is highlighted by the fact that COPIMAN (Technical Committee on Maintenance of the Pan American Federation of Engineering Societies) is joining the comparison effort.

The result of the activity will be a document pointing out the similarities and documenting the differences in the indicators. The document is in progress, and the first step has been taken to identify the similarities between the EN standard and the SMRP metrics.

The first indicators compared and identified as similar from prEN 15341 and the SMRP Metrics are:

To increase understanding and the application of the indicators, EFNMS and SMRP organizes workshops based on the indicators or metrics.
