Run‑to‑Failure Maintenance: When It Makes Sense & How to Plan It

Run‑to‑failure maintenance is a deliberate strategy that only triggers repair when equipment actually breaks. When applied correctly, it can reduce overall maintenance spend while maintaining reliability. Below, we explain when this approach is appropriate, how to plan it, and how a CMMS can streamline the process.

When to Consider Run‑to‑Failure

1. Predictable Failure Probability

Equipment whose failure likelihood stays low over time—often because of stable wear‑and‑tear or robust design—are prime candidates. Conversely, devices that spike in failure as they age or when they are new (due to defects or installation errors) are better served by proactive care. Reliability‑Centred Maintenance (RCM) charts these patterns, helping managers decide which assets fit the run‑to‑failure model.

2. Low Criticality

If an asset’s failure poses minimal safety risk or financial impact—think a roof light or a non‑critical pump—it can be safe to let it run until it breaks. The cost of downtime is outweighed by the savings from avoiding unnecessary maintenance.

3. Accessibility Challenges

When routine checks are difficult—due to height, confined spaces, or remote locations—run‑to‑failure can be a practical interim solution until infrastructure changes enable easier access.

4. Cost Comparisons

Run‑to‑failure is justified when the total cost of preventive upkeep exceeds the expected cost of failure, including indirect impacts such as lost production or customer dissatisfaction. A thorough cost‑benefit analysis should capture all direct and indirect expenses.

Planning Is Key

Even a run‑to‑failure strategy requires rigorous planning. Define who will handle the repair, what spare parts are on hand, and the exact steps to follow once a failure occurs. This pre‑planning transforms a reactive response into a controlled, efficient operation.

Leveraging Your CMMS

Use your Computer‑Aided Maintenance Management System (CMMS) to create a Run‑to‑Failure maintenance template. When an asset fails, the template auto‑generates a work order, ensuring consistency and speed.

Conclusion

Run‑to‑failure can be a cost‑effective maintenance strategy when chosen for the right assets and backed by comprehensive planning. By integrating it into your CMMS, you maintain control, reduce surprises, and keep maintenance budgets in check.
