Maintenance, as a form of production support, has become increasingly important to ensure equipment availability, quality products, on-time deliveries, and plant safety. Condition based maintenance, where it fits, is one maintenance solution that can increase the effectiveness of maintenance execution. Condition based maintenance is though not utilized in Swedish industry to the extent one would have expected. One reason for this is a gap between theory and practice when it comes to implementing and operating a condition based maintenance approach. Therefore, the purpose of this paper is to investigate how a condition based maintenance approach can be implemented in an industrial setting, and to develop a method that can assist companies in their implementation efforts. The conclusions can be summarized as follows: implementing condition based maintenance consists of many general enabling factors, and it is highly important to consider the interplay between technology, humans, and the organization, rather than just focusing on technology.
