When to use it
Turn critical process controls into short recurring checks performed by different management layers and linked to reaction and KPIs.
QAPP principle
The application structures the workflow, evidence, ownership and links. Engineering judgement and customer-specific requirements remain with the competent team.
Inputs and preparation
- Process- and risk-specific questions
- Audit frequency and layers
- Owners and escalation rules
- Findings, actions and effectiveness KPIs
Workflow
- Select questions that verify important controls rather than generic statements.
- Define who audits and at what frequency.
- Record the finding and immediate reaction.
- Link actions to owner and due date.
- Measure LPA effectiveness and adjust the checksheet.
How QAPP can digitise it
| Element | Digital implementation |
|---|---|
| Data | Structured fields, controlled lists, revisions and attached evidence. |
| Ownership | Owners, due dates, notifications, approvals and escalation. |
| Traceability | Links between records, actions, revisions and resulting evidence. |
| Review | Status, open risks, overdue actions and management dashboards. |
AIAG alignment
AIAG CQI-8 · Layered Process Audit Guideline
AIAG CQI-8 links LPA with KPIs, expands ownership beyond Quality, recommends roles/responsibilities, process-specific questions and management review. QAPP can schedule audits, distribute ownership and track findings, closure and trends.
