Choosing the Right Strategy

"Predictive will save millions!"

Or will it? Let's cut through the noise.

Clear Definitions

📅 Preventive (PM)

Time-based or usage-based

  • Oil every 3 months
  • Filter every 1000 hours

📊 Predictive (PdM)

Condition-based

  • Replace when vibration trends up
  • Act when data shows degradation

Decision Framework

1
Can failure be predicted?No → PM
2
Is asset critical?Yes → PdM
3
Have the capability?No → PM first
4
Cost effective?Often → Both
