QAPP CI · SUPPORTING CI METHOD
SMED
Reduce changeover time by separating internal from external activities and simplifying the remainder.
When it helps
Reduce changeover time by separating internal from external activities and simplifying the remainder.
Data and preparation
Activity times, sequence, resources, movements, adjustments and first good piece
Practical workflow
- Time the real changeover from last good to first stable good piece.
- Separate internal versus external work.
- Convert as much internal work as possible to external.
- Simplify clamps, adjustments and movements.
- Standardise and confirm repeatability.
What QAPP records
| Before | During | After |
|---|---|---|
| Scope, baseline, ownership, evidence | Actions, timestamps, observations, exceptions | Result, effectiveness, standard update, follow-up |
Connection to AIAG
This is a supporting Continuous Improvement method, not an AIAG Core Tool. In QAPP, findings can feed a CQI-20/8D problem-solving workflow and, when the process risk/control changes, trigger review of PFMEA, Control Plan, MSA/SPC or other applicable Core Tool records.
Interpretation limits
Do not use the tool as a ritual. Define a measurable problem, baseline and decision rule, then verify whether the change improved the process without creating another risk.
