Quality management, by means of total quality management (TQM), is considered to foster organisational performance characterised by competitiveness and long‐term profitability. Since the benefits of quality management cannot be achieved without the sustained performance of equipment affecting product quality, maintenance management has become important. This has led to the development of maintenance methodologies, such as total productive maintenance (TPM) and reliability centred maintenance (RCM). TQM, TPM and RCM implementation have, however, often failed or been poorly executed. This has affected organisations' performance and ultimately survival in a competitive environment. This paper includes a comparative study of literature on TQM, TPM and RCM implementation, focusing on organisational change. The study found several common categories of activities when implementing TQM and the maintenance methodologies. These categories can be considered crucial to obtain management and employee commitment. Case studies on TQM, TPM and RCM implementation are used to validate the categories identified, and to yield recommendations on the handling of activities within these.

For several branches of industry, an increasingly competitive environment has raised important questions concerning maintenance in plant systems. For example, the 1996 deregulation in Sweden’s electricity sector has resulted in increased competition among the country’s power producers. To survive the competition, suppliers have to reduce maintenance costs, i.e. handle maintenance more efficiently. Risk analysis is one tool decision makers can use to help them prioritise as they plan maintenance actions. There are a number of different approaches to risk analysis. As the results of an analysis must form a reliable basis for decision making, it is important to consider whether the quality of the results will vary significantly with the risk analysis approach chosen. This paper presents a comparative study based on three independent risk analyses performed on a specific hydro‐power plant. The comparison and evaluation of the analyses reveal major differences in performance and results, along with various factors that affect the quality of the analyses. The study establishes the importance of a well‐planned requirement specification and the need to analyse and interpret risk analysis results, before making maintenance decisions.
