Sammanfattning:
Maintenance is an ongoing process for any system with the purpose to maintain its given function during its lifetime. Since maintenance is an integrated part of the business process, correctly performed maintenance creates increased business values. For this, the management must strive for continuous improvement of maintenance process. One powerful tool for this purpose is benchmarking, eg comparing own performance with best in the class or other high performance organizations and learning what they do to achieve their high level of performance. To make a successful comparison, common performance indicators must be identified and used. Performance indicators can broadly be classified as lead or lag indicators, where lead indicators are performance drivers and lag indicators are outcome measures. Today, there is a lot of performance indicators in use connected to maintenance, covering for example the area of safety, asset condition and asset reliability, maintenance performance and cost control.

This paper presents two case studies, the first one deal with benchmarking the maintenance process and where as the second one compares the use of maintenance performance indicators at the Swedish National Rail Administration (Banverket). We discuss some benchmarking results indicating for example how maintenance strategies, i.e. proactive or reactive, impact the maintenance costs and the ratio of unplanned maintenance. We also emphasize that many of the maintenance performance indicators are used by various organizations abroad and thus provide Banverket an opportunity to benchmark its operation internationally to improve its performance. One of the findings in both case studies is that there are two critical parameters that are missing from the list of indicators, namely traffic volume and infrastructure age. An attempt is also made to analyze the impact of chosen indicators, as well as suggesting future maintenance indicators for future benchmarking.
