Reliability Centered Maintenance, often known as RCM, is a process to ensure that assets continue to do what their users require in their present operating context.
It is generally used to achieve improvements in fields such as the establishment of safe minimum levels of maintenance, changes to operating procedures and strategies and the establishment of capital maintenance regimes and plans.
Successful implementation of RCM will lead to increase in cost effectiveness, machine uptime, and a greater understanding of the level of risk that the organization is presently managing.
Let's look at Reliability-centered Maintenance as a process to establish the safe minimum levels of maintenance. RCM starts with the seven (7) questions below, worked through in the order that they are listed:
- What is the item supposed to do and its associated performance standards?
- In what ways can it fail to provide the required functions?
- What are the events that cause each failure?
- What happens when each failure occurs?
- In what way does each failure matter?
- What systematic task can be performed proactively to prevent, or to diminish to a satisfactory degree, the consequences of the failure?
- What must be done if a suitable preventive task cannot be found?
