UNDERSTAND THE CONCEPT
Reactive work responds after a fault is discovered. Preventive work follows a time or usage interval. Condition-based work responds to observed degradation, while predictive methods estimate a future condition or event from data. These approaches can coexist on the same equipment.
Choose tasks by failure mechanism, consequence and the ability to detect useful warning. A calendar replacement does not address every failure mode, and a sensor does not automatically create a predictive programme. Record why a task exists, what finding changes the decision and when its effectiveness will be reviewed.
Questions to take back to your team
- Which failure mode does this task address?
- Is there enough warning to act on a condition finding?
- Who reviews the strategy when failures recur?
