APQP Documents Checklist
This comprehensive APQP (Advanced Product Quality Planning) Documents Checklist provides a structured approach to ensure all advanced product quality planning requirements are systematically fulfilled. The checklist guides cross-functional teams through every critical phase — from capturing the voice of the customer and analyzing historical lessons learned, through project goal definition, product and process design development, full validation testing, and post-launch continuous improvement activities. Use this checklist to verify completeness, track progress, and maintain compliance with customer and industry APQP standards throughout the entire product lifecycle.

How to Use This Checklist
- Assign a cross-functional team member to own each phase and record completion against the answer scale.
- Work through the items in sequence, attaching or referencing the supporting document for each one as you go.
- Escalate blockers — missing customer-specific requirements, incomplete design reviews, or open change-control actions — to the project lead.
- Repeat the checklist at each phase gate to evidence progress and keep the audit trail current.

What APQP is
Advanced Product Quality Planning (APQP) is a structured method for planning and managing the development of a new product so that it meets customer requirements the first time and every time. It organises the work into defined phases and requires documented evidence at each one, so that a cross-functional team can move from understanding what the customer wants to proving that the process can deliver it consistently. This checklist walks you through every phase of that work, from capturing the voice of the customer through to continuous improvement after launch. It covers the full sequence: pre-planning and foundation, planning and project definition, product design and development, process design and development, product and process validation, and launch and continuous improvement.
Why it matters
APQP ties together the activities that most often cause quality problems when they are skipped or rushed. Capturing the voice of the customer, identifying customer-specific requirements, and reviewing historical lessons learned early means the team designs to real needs rather than assumptions. Risk analysis through Design FMEA and Process FMEA, along with control plans and process capability studies, surfaces failure modes and variation before they reach production. Validating the product and process, submitting Production Part Approval, and confirming packaging and measurement systems gives the customer objective evidence of conformance. After launch, collecting customer feedback, tracking corrective actions, and verifying reduction in process variation keeps the product improving rather than drifting.
What a good APQP process covers
A complete APQP effort addresses six phases: 1. **Pre-planning and foundation** — capture and document the voice of the customer (VOC), align with quality policy, business plans, and marketing strategies, review the historical lessons-learned database, conduct benchmarking, complete reliability studies, identify customer-specific requirements (CSRs), and establish project priorities and KPIs. 2. **Planning and project definition** — define project goals, verify the customer purchase order, obtain engineering drawings and specifications, set measurable design, quality, and reliability goals, develop the preliminary bill of materials and process flow chart, identify preliminary special characteristics, and develop a product assurance plan. 3. **Product design and development** — complete the DFMEA, perform DFMA analysis, conduct the design verification plan and report, hold formal design reviews, develop the prototype build control plan, finalise engineering drawings and specifications, implement change control, and define new equipment, tooling, and facilities requirements. 4. **Process design and development** — conduct the quality system review, develop the floor plan layout, complete the PFMEA, finalise the detailed process flow chart, develop the characteristics matrix, prepare the pre-launch control plan and detailed process instructions, and plan MSA and preliminary process capability studies. 5. **Product and process validation** — execute the production trial run, complete the measurement systems evaluation, conduct the preliminary process capability study, prepare and submit PPAP, perform production validation testing, conduct packaging evaluation, and finalise the production control plan. 6. **Launch and continuous improvement** — collect and document customer feedback, conduct performance assessments, implement and track corrective actions, verify reduction in process variation, and rate customer satisfaction improvement. Throughout, documentation is the deliverable. The checklist is structured so that every requirement has an owner, a status, and an artefact behind it.
How to carry it out
Work through the checklist in phase order. Start by confirming the customer's requirements and any customer-specific requirements, and by reviewing past lessons learned so earlier problems are designed out. Define measurable goals and KPIs before design work begins. Use DFMEA and DFMA to shape the design, then verify it against the design verification plan and hold formal design reviews at defined points. Before committing to production, complete the PFMEA, finalise the process flow, build the characteristics matrix, and prepare the pre-launch and production control plans. Validate by running the production trial, evaluating the measurement system, studying process capability, submitting PPAP, and testing production and packaging. After launch, keep the loop closed: gather customer feedback, assess performance, act on corrective actions, and confirm variation is reducing. The document set this checklist calls for typically includes engineering drawings and specifications, a preliminary bill of materials, process flow charts, DFMEA and PFMEA records, control plans, a product assurance plan, MSA plans, process capability studies, PPAP submission, and packaging specifications. Each item in the checklist corresponds to one of these documents or one of the activities that produces it.
Who this checklist is for
This checklist is for quality engineers, project and programme managers, design and manufacturing engineers, and cross-functional product teams working in manufacturing environments where APQP is required by the customer or expected by the industry. It is also useful for auditors and reviewers who need to confirm that the required documents exist and are current at each phase of a product development programme.
