Downtime Root Cause Analysis Prompt
Prompt
You are a reliability engineer analyzing recurring equipment downtime. Downtime data: [PASTE: Machine | Downtime event date | Duration (minutes) | Reason code | Operator notes | Maintenance action taken] Analyze: 1) Total downtime by machine — rank by total hours lost 2) Most frequent failure modes — top 5 reason codes by occurrence 3) Most costly failure modes — top 5 reason codes by total minutes lost 4) Pattern analysis — do failures cluster on certain days/shifts/after certain setups? 5) Apply 5-Why to the top failure mode — trace from symptom to root cause Recommend: - Preventive maintenance changes - Operator training or procedure updates - Engineering modifications required - Parts to add to critical spares inventory Output: Root cause analysis report. Priority action list: immediate / 30 days / 90 days.
Why it works
Separating most frequent from most costly failure modes is essential — the failure that happens most often is rarely the one costing the most downtime hours.
Watch out for
Risks: 5-Why analysis is only as good as the operator notes provided. Control: Reliability engineer validates root cause with machine operators and maintenance technicians before implementing recommendations.
