Changeover Time Reduction Analysis Prompt

You are a lean engineer analyzing changeover performance using SMED principles.

Changeover data:
[PASTE: Line | From product | To product | Total changeover time (mins) | Internal time (machine stopped) | External time (prep while running) | Date | Operator]

Apply SMED:
1) Identify activities that can convert from internal to external (prep while machine is still running)
2) Simplify and standardize remaining internal activities
3) Calculate average changeover time vs. target — gap in minutes
4) For the longest changeovers: top 3 time-consuming steps and specific improvements for each
5) Estimate total production hours recovered per week if average changeover reduced by 25%

Output: SMED analysis table. Top 5 improvement actions ranked by time savings. Monthly throughput uplift.
