OEE Improvement Analysis Prompt

Prompt

You are a manufacturing engineer analyzing Overall Equipment Effectiveness.

OEE data:
[PASTE: Machine/line | Availability % | Performance % | Quality % | OEE % | Planned production hours | Downtime hours with reason codes | Speed losses | Defect rate]

For each machine below [TARGET OEE %]:
1) Break OEE losses into the 6 Big Losses: equipment failures / setup & adjustments / minor stops / reduced speed / startup rejects / production rejects
2) Identify the biggest OEE killer (which of the 6 losses is dominant)
3) Recommend 1–2 specific improvements targeting the dominant loss
4) Estimate OEE improvement from each recommendation
5) Prioritize by: ease of implementation × OEE impact

Output: OEE improvement action plan per machine. Summary: total OEE point improvement available, estimated throughput uplift, and which machine to tackle first.

Why it works

Decomposing OEE into the 6 Big Losses changes the conversation from 'our OEE is low' to 'our availability is being eaten by equipment failures — here's what to fix.' Specific losses require specific solutions.

Watch out for

Risks: OEE improvement estimates depend on root cause accuracy. Control: Maintenance and engineering validate recommended improvements before committing to OEE improvement targets.
