Predictive Maintenance
Predictive maintenance uses measured equipment condition to identify deterioration and plan work before failure.
Predictive maintenance uses measurements of equipment condition to detect deterioration and determine when maintenance is needed. The aim is to act before the equipment experiences significant degradation or failure.
It differs from preventive maintenance performed solely on a preset calendar or operating-hours schedule. Its decisions rely on condition evidence, such as measurements showing a change in how equipment is functioning.

Frequently Asked Questions
Is predictive maintenance just another fixed service schedule?
No. Its defining feature is equipment-condition evidence. A preset calendar or operating-hours interval is a preventive approach.
