Protect critical functions
Start with the effect of failure on safety, quality, delivery, and continuity.
RCM turns possible failures into verifiable decisions: which function to protect, which evidence to observe, and when preventive work actually reduces risk.
Start with the effect of failure on safety, quality, delivery, and continuity.
Define an intervention only when a failure mode and an observable signal support it.
Compare recurrence and subsequent performance to improve the maintenance plan.
Reliability Centered Maintenance was born in commercial aviation with the 1978 Nowlan and Heap report, which showed that most failures do not depend on equipment age. SAE JA1011 defines what a process must meet to be called RCM.
What the asset functions are, how it can fail to fulfill them, what causes each functional failure, what happens when it fails, what the consequences are, which proactive task prevents it, and what to do when no suitable task exists.
Failure modes and effects analysis lists, for each function, the failure modes and their effects. Without that inventory, task selection is done by habit. With it, every task in the plan answers a specific failure mode.
Hidden failures (unseen until something else fails), safety or environmental, operational (affecting production) and non-operational (only the repair cost). The consequence decides how much is worth investing to prevent the failure.
A scheduled routine without a failure mode, consequence and observable signal becomes administrative cost. RCM requires explaining what risk each task reduces.
Criticality changes with the line, the shift and backup availability. iGromi lets you see that context before turning an observation into an intervention.
Select a critical asset, define a function, record the failure mode and agree on a verification signal. Then expand only what proves value.
When RCM concludes that an on-condition task is right, a signal is needed: vibration, temperature, current or acoustics. The sensor and the threshold are the execution of the analysis, not a separate project.
