Maintenance Strategy

What this topic covers

How corrective, preventive, predictive and redesign choices form an asset care plan.

Core ideas

A strategy should connect each significant failure mode with an appropriate control.

Over-maintenance can create cost and maintenance-induced failures, while under-maintenance increases risk.

Task effectiveness should be reviewed using failure history and condition evidence.

Program tradeoffs

Condition-based maintenance only works when degradation can be detected with enough lead time to act.

What good evidence looks like

Backlog and work priority should reflect risk, readiness and consequence—not age alone.

Lifecycle perspective

Repeat failures are opportunities to remove causes through design, installation, operating or maintenance improvements.
