Where traditional preventive maintenance breaks down—and how reliability thinking fills the gap.
Preventive maintenance was designed for stable operating conditions. Modern plants rarely operate under those assumptions.
The limits of time-based maintenance
Fixed intervals ignore operating variability and failure behavior.
PM overload creates false confidence
More tasks do not equal better reliability.
Reliability focuses on failure mechanisms
Understanding how and why assets fail changes maintenance priorities.
Integrating PM with condition and inspection
Preventive tasks work best when informed by asset condition.
Preventive maintenance remains useful—but only as part of a broader reliability strategy.
