Root cause analysis on a fifteen-minute budget
Formal RCA is too heavy for most failures, so it never happens at all. A light version run consistently beats a rigorous one run twice a year.
Ask a maintenance team whether they do root cause analysis and the honest answer is usually: on the big ones. Which means the failures that repeat quietly — the ones actually consuming the budget — are never examined, because each individual instance is too small to justify a formal process.
The fix is not more rigour. It is a version cheap enough to run on the small ones.
Trigger it with a rule, not a judgement
If deciding whether a failure deserves analysis is itself a decision, it will not get made under pressure. Set a rule and let it fire automatically.
- Any failure on a critical-tier asset.
- Any repeat failure on the same asset within ninety days.
- Any failure that cost more than your approval threshold.
- Any failure that caused an unplanned stop, regardless of cost.
Everything else closes normally. This typically flags a handful of work orders a week, which is a sustainable volume.
Five whys, in the work order, at closure
The analysis happens where the work already is, at the moment the technician has the context. Not in a separate document, not in a meeting the following week.
The discipline is to keep asking until the answer stops being a component and starts being a decision. "The bearing failed" is a component. "The bearing failed because the alignment was never checked after the last motor swap, because motor swaps have no post-work check" is a decision — and decisions are fixable.
Write the finding where the next person will see it
A finding filed in a report is a finding lost. A finding written into the asset record is read by whoever next opens a work order against that asset, which is exactly the person who needs it.
One paragraph is enough: what failed, why, and what should change. Nobody has ever complained that an RCA note was too short.
Convert findings into something structural
An analysis that ends in a note has produced knowledge. An analysis that ends in a changed PM task, a new checklist line, a revised spare, or a design change has produced reliability. Aim for the second, and accept the first when that is all the evidence supports.
The post-work check in the example above becomes a two-line addition to the motor-swap task. That is the whole return on the exercise.
Review the set quarterly
Individual findings are useful. The pattern across thirty of them is where the real signal lives, and it is invisible unless someone reads them together. An hour a quarter, with the findings sorted by asset class, reliably surfaces one thing nobody had noticed.
