APQP Guide: Advanced Product Quality Planning
APQP is the structured way a manufacturing team plans a new product launch so that problems are found on paper and in trials, not at the customer. This guide walks through the phases in the order they are used on real projects.

What it means
Advanced Product Quality Planning (APQP) is a cross-functional framework that defines what must be done, by whom and by when, from concept to series production. It is organised in five phases, and PPAP is one of its final outputs.
Why it matters in manufacturing
Most launch problems — wrong gauges, unstable processes, missing packaging, late tooling — are planning failures. APQP gives the team a shared timeline and clear gate reviews, so risks are raised early when they are cheaper to fix.
The five APQP phases
- 1
Plan and define
Capture customer requirements, targets and special characteristics. Form the cross-functional team and build the project timeline.
- 2
Product design and development
Design reviews, DFMEA, prototype build and drawing release, where the supplier is design-responsible.
- 3
Process design and development
Process flow, PFMEA, pre-launch control plan, floor layout, work instructions and packaging standards.
- 4
Product and process validation
Significant production run, MSA, preliminary capability studies, production control plan and PPAP submission.
- 5
Launch, feedback and corrective action
Monitor early production, reduce variation, track customer feedback and capture lessons learned.
Practical shop-floor example
Illustrative learning example — not a client result
Example: launching a new bracket assembly
At phase 3 the team's PFMEA shows a high risk of a missing weld nut. Instead of adding final inspection, they design a sensor on the welding fixture that stops the cycle if the nut is absent. At phase 4 the trial run confirms the error-proofing works, and the control plan includes a daily check of the sensor.
Common mistakes
- Starting tooling before process risks are reviewed.
- Holding gate reviews only as status meetings with no real decisions.
- Leaving Production and Maintenance out of the team until launch week.
- Not carrying lessons learned from previous launches into the new plan.
Practical checklist
- Customer requirements and special characteristics listed
- Cross-functional team and timeline agreed
- DFMEA/PFMEA completed and reviewed
- Pre-launch and production control plans ready
- Gauges approved through MSA
- Trial run results reviewed
- Lessons learned recorded
Frequently asked questions
What is the difference between APQP and PPAP?
APQP is the complete planning process for a launch. PPAP is the approval package submitted near the end of APQP to show the process is ready.
Who owns APQP?
It is cross-functional. A project or quality lead usually coordinates it, but Design, Production, Purchasing, Maintenance and Logistics all own deliverables.
