This paper aims to examine the relationship between quality management orientation dimensions and maintenance performance. The concept of quality management orientation is proposed and defined as a set of norms and values regarding customer orientation, quality responsibility, prevention and process orientation. Empirical data were drawn from a sample of Slovenian organisations in order to address the research question. The data were analysed using exploratory factor analysis, confirmatory factor analysis, correlation analysis and regression analysis. The findings indicate that quality management orientation is important predictor of maintenance performance. Data analysis results also show that quality management orientation dimensions are positively related to maintenance performance. By testing the impact of quality management orientation on maintenance performance, this study shows that strong foundation on quality management orientation is an effective way of improving maintenance performance.
