Nonconformity / complaint
Record issue, product/process context, containment and evidence.
How the tools connect
AIAG describes APQP, Control Plan, PPAP, FMEA, MSA and SPC as interconnected Core Tools. QAPP keeps the relationships visible instead of treating each document as an isolated file.
APQP→PFMEA→Control Plan→MSA/SPC→PPAP
What QAPP adds
Version history, ownership, links between risks and controls, action tracking, evidence and dashboards. QAPP supports the workflow; it does not replace engineering judgement or certify compliance.
Quality methods
Open a method to see when to use it, required inputs, workflow, links to other tools, implementation ideas in QAPP and official sources.
01AIAG CORE TOOL
APQP
Plan product and process maturity through risks, gates, ownership and launch-readiness evidence.
Open method →02AIAG CORE TOOLControl Plan
Turn risks and requirements into concrete controls: what to check, how, how often and how to react.
Open method →03AIAG CORE TOOLPPAP
Organise evidence that the production process can consistently meet engineering and specification requirements.
Open method →04AIAG & VDAPFMEA
Structure process functions, failure modes, effects, causes, controls and action priorities.
Open method →05AIAG CORE TOOLMSA
Check whether the measurement system is good enough for decisions made from the data.
Open method →06AIAG & VDA 2026SPC
Separate common variation from special signals and connect stability to control and capability decisions.
Open method →07PROBLEM SOLVING8D
Structure the team, containment, demonstrated root cause, corrective action and effectiveness verification.
Open method →08AIAG CQI-20Effective Problem Solving
A robust framework for problem definition, analysis, cause, action, verification and recurrence prevention.
Open method →09AIAG CQI-8Layered Process Audits
Connect short frequent checks to ownership, KPIs, escalation and process improvement.
Open method →Important distinctionAIAG alignment means the workflow is designed around the intent and relationships described by the referenced publications. It does not mean QAPP reproduces licensed manual content or guarantees customer-specific compliance.
Operational quality workflows
CAPA / 8D
Move from correction to demonstrated root cause and verified corrective action.
Audits
Plan, findings, ownership, deadlines, closure evidence and effectiveness.
Change feedback
Use lessons learned to update PFMEA, Control Plan and related process controls.
