Operational reliability - that is what we actually achieve in our Plants, is almost always lower than the intrinsic reliability that the Plants were designed and built to achieve. To bridge this gap, some managers look for silver bullets. Thus RCM, TPM, Six Sigma or some other process is selected to improve reliability performance. If these are not part of a well thought out plan, sustained results are hard to achieve. The plan will follow steps such as those described below.
Event data analysis can be a very useful in understanding how and when assets fail. It can also provide insight to help plant personnel understand what action to take and when to take it. In other words, it helps in the process of building a strategy for asset performance management.
When we think about maintenance strategies, the words predictive, preventive, corrective, and breakdown spring to mind. There is however an important class of tasks that we do to ensure that our equipment and Plant remains safe and productive. These tasks are based on a Detective Maintenance strategy.

With machinery and Plants becoming increasingly more complex, the proportion of such tasks in the total maintenance program is growing.
