Repeat failure analysis turns scattered work orders into recurring failure patterns. The goal is not to prove a root cause from text alone. It is to identify where restoration keeps repeating and where deeper investigation or a different maintenance strategy is justified.

The asset repeatedly trips, leaks, jams, overheats, loses pressure, or produces the same abnormal condition.
The same bearing, sensor, belt, coupling, seal, valve, drive, or other component is repeatedly repaired or replaced.
A documented underlying contributor recurs, such as contamination, misalignment, inadequate lubrication, wiring damage, or a process condition.
CMMS recurrence is rarely a perfect match on one failure code. Work-order language varies by technician, shift, component name, shorthand, symptom, and level of detail. Useful analysis normalizes those differences without pretending uncertain records are exact.
Resolve aliases, parent assets, line-level charging, retired IDs, and duplicate equipment records before comparing recurrence.
Group comparable terms such as “belt tracking,” “belt walking,” and “conveyor belt off center” while keeping the original text available for review.
Define a recurrence window appropriate to the asset and failure. Three events in one week may represent a different problem than three similar events over five years.
When records are vague, label the pattern as suspected recurrence and identify what better closeout or inspection evidence is needed.
| Signal | What it adds |
|---|---|
| Event count | Shows recurrence frequency. |
| Downtime | Shows operational interruption when captured consistently. |
| Labor hours | Shows maintenance capacity consumed by restoration. |
| Parts / cost | Shows material burden and repeat replacement. |
| Emergency priority | Shows schedule disruption and response urgency. |
| Safety / quality consequence | Can justify escalation even when event count is low. |
| Time between repeats | Shows whether recurrence is accelerating or repair life is shorter than expected. |
For each high-priority recurrence, document the evidence, current hypothesis, required investigation, action owner, target date, and what future condition will demonstrate that the problem improved. Without verification, the organization can complete corrective actions while the same failure pattern continues.
Combine recurrence with downtime, labor, cost, and consequence to rank asset priorities.
Improve the history needed to distinguish symptom, finding, correction, and verified cause.
Turn repeat failures and other work history into a prioritized maintenance action register.
