At the same time, thelimitations of maintenance systems are becoming increasingly apparent, no matter how much they are computerized. In the face of this avalanche of change, managers everywhere are seeking a new approach tomaintenance. They want to avoid the false starts and dead ends that always accompany major upheavals.

If it is applied correctly, RCM transforms the relationships between the undertakings that use it, their existing physical assets and the people who operateand maintain those assets.
