Risk-based dependability approach to maintenance performance measurement

摘要

Purpose - The purpose of this paper is to describe how a risk-based dependability approach can be used to link maintenance performance measurement and management to overall objectives within an organization. Design/methodology/approach - The applied study approach is a case study at Trafikverket (the Swedish Transport Administration). Qualitative data were collected through interviews, workshops and document studies, while quantitative data was collected through data bases. As a framework for analysis, international standards within the risk and dependability areas were applied. Finally, the conclusions of the study were verified by key informants. Findings - Through the proposed risk-based dependability approach, critical availability goals are communicated with and involve top management. The approach also contributes to enhanced data and information quality by pinpointing critical data and information for dependability management activities. The proposed availability indicator can be used to monitor the effect of dependability management activities aimed at different indenture levels of the infrastructure and related to the responsibility of different hierarchical levels of the organization, e.g. different maintenance echelons. Practical implications - The proposed approach strengthens the internal control of an organization by supporting the achievement of: objectives that are aligned with and support the mission; operations with an effective and efficient use of resources; reliable operational and financial reporting; compliance with applicable laws and regulations. Originality/value - By integrating risk management in the work with availability goals included in the balanced scorecard, a more holistic and risk-based dependability management practice is achieved.
