What problem it solves
Structure the response to significant problems from customer protection through demonstrated cause, permanent corrective action and recurrence prevention.
Connected system
QAPP links the method with ownership, evidence, actions and upstream/downstream quality records.
Inputs
- Verifiable problem description and impact
- Team and responsibilities
- Containment and its validation
- Demonstrated causes and escape point
- Permanent corrective actions and verification criteria
- Lessons learned and system updates
Method flow
- D1 — establish the team.
- D2 — describe the problem using verifiable data.
- D3 — protect the customer/process with validated containment.
- D4 — demonstrate root cause and escape point.
- D5/D6 — select, implement and validate permanent corrective action.
- D7/D8 — prevent recurrence, standardise and close with evidence.
QAPP implementation
| Need | QAPP implementation |
|---|---|
| Structure | Controlled fields, revisions, linked records and required evidence. |
| Actions | Owner, due date, approval, escalation and effectiveness verification. |
| Traceability | History of changes and links to related Quality / CI / Analytics records. |
AIAG alignment
AIAG provides dedicated 8-D training and CQI-20 guidance for robust problem solving. QAPP treats 8D as an evidence- and gate-based workflow rather than a form that can be closed by filling fields.
Open official source →Common mistakes
Do not treat the digital form as proof that the method was applied correctly. The method requires competent analysis, representative evidence and customer-specific requirements where applicable.
