APQP — Advanced Product Quality Planning

APQP is a structured framework used in the automotive industry to define and establish the steps needed to ensure a product meets customer requirements. It organises product development into five phases with defined deliverables, culminating in PPAP submission.

Why companies use it

·Mandated by major automotive OEMs (Ford, GM, Stellantis) and codified in the AIAG APQP manual
·Creates a shared, structured timeline between customer and supplier to manage launch risk
·Ensures quality planning deliverables (DFMEA, PFMEA, Control Plan, MSA, SPC) are completed before production
·Reduces costly production launches and warranty claims through front-loaded risk elimination

What hiring managers look for

·APQP experience signals that a candidate can manage complex, cross-functional quality programmes
·Understanding all five APQP phases shows end-to-end product development knowledge
·Tier-1 suppliers need engineers who can be the customer-facing quality lead, not just complete templates
·Being able to create and maintain an APQP timing plan demonstrates project management capability

Typical interview questions

Describe the five phases of APQP and the key deliverable from each phase.

How do you manage customer-specific requirements within the APQP framework?

What would cause you to recommend delaying a production launch during APQP?

How does APQP differ from a standard engineering project plan?

Have you ever run an APQP for a new product launch? What was the biggest challenge?

Common mistakes

·Treating APQP as purely a document-completion exercise rather than a risk management process
·Starting PFMEA and Control Plan too late — they must inform tooling and process design, not follow it
·Missing cross-functional team involvement in early phases — purchasing, manufacturing, and quality must all engage from Phase 1
·Not tracking open actions through the APQP timing plan, allowing gate approvals to slip
·Confusing APQP (the planning process) with PPAP (the deliverable package for customer approval)

Real engineering example

A Tier-1 automotive electronics supplier used APQP when launching a new motor control ECU for an EV platform. During Phase 2 (Product Design and Development), the DFMEA identified a power surge failure mode the customer had not specified a requirement for. By adding a TVS diode array in Phase 2, they avoided a mid-production ECR that would have cost €280k in tooling changes and delayed launch by six weeks.
