QAPP CI · SUPPORTING CI METHOD
Andon
Turn an abnormality into a visible signal with owner, response time and escalation.
When it helps
Turn an abnormality into a visible signal with owner, response time and escalation.
Data and preparation
Abnormality type, station, timestamp, status, owner, response and restoration
Practical workflow
- Define conditions that trigger the signal.
- Define who responds and in what time.
- Allow visible acknowledgement and escalation.
- Record cause/stoppage and restoration.
- Use history for problem solving and prevention.
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.
