Running a bad-actor review meeting
A bad-actor review is a recurring cross-functional meeting that identifies the small number of assets responsible for a disproportionate share of failures, downtime or cost, and assigns owned actions to eliminate their recurring problems. It focuses scarce reliability effort on the worst offenders rather than spreading it thinly across the whole plant.
What it is
Bad actors are the assets that fail repeatedly or cause the most lost production — the classic vital few among the trivial many. The review is a regular forum, typically monthly, where maintenance and operations rank failures by impact, agree which assets are the current worst offenders, and commit named owners and dates to the root-cause actions that will stop the recurrence.
Why it is done
Without a deliberate focus, maintenance effort scatters across every fault report and the same machines keep failing because nobody owns their underlying problem. A bad-actor review applies the Pareto principle to reliability, concentrating analysis and corrective action where the payback is largest, and creates the accountability that turns a list of repeat failures into a list of permanently solved problems.
How it is done
Failure and downtime data are pulled from the maintenance system and ranked by cost or lost-time impact to surface the top offenders. The meeting reviews the current list, confirms which assets warrant deeper root-cause analysis, and assigns each an owner and target date for the corrective action. Progress on previously agreed actions is reviewed first, so commitments are tracked to closure, and assets drop off the list only once their failures genuinely stop.
- Rank failures by impact
- Confirm worst offenders
- Review prior actions
- Assign owners & dates
- Trigger root-cause work
- Track to closure
What to watch for
The meeting fails when it becomes a status report with no owned actions, or when the same bad actors reappear month after month because actions are assigned but never closed. Ranking by failure count rather than business impact also misdirects effort toward frequent but trivial faults.
