Predictive vs Preventive Maintenance
Apply predictive technologies to condition-dependent assets while retaining schedule-based maintenance for safety-critical equipment under IEC 61508.

Regulations
Business Context
Preventive maintenance follows predetermined schedules regardless of
actual equipment condition. Predictive maintenance uses real-time
condition monitoring to determine when intervention is genuinely
required.
The Contradiction
Preventive maintenance provides structured planning.
Predictive maintenance improves maintenance efficiency through
condition-based decisions.
Why It Exists
Preventive maintenance simplifies scheduling but frequently replaces
equipment that remains serviceable, while predictive maintenance depends
upon reliable monitoring technologies and engineering interpretation.
Direction
Combine preventive maintenance for regulatory and safety-critical
equipment with predictive technologies for condition-dependent assets.
