DFSS Instructor Prep · Module 4 Layer C — Industry & Quality Framework

APQP, PPAP & IATF 16949 in the Design Context

The framework inside which DFSS lives. The DMADV roadmap doesn’t exist in isolation at Yazaki — it runs in parallel with APQP gates, feeds the PPAP submission, and is governed by IATF 16949 Section 8.3. This module gives you the literacy to map DMADV onto the framework your participants actually operate inside.

DFSS is sometimes taught as a parallel universe with its own vocabulary. At a real Tier-1, it is not. Every DMADV project happens inside an APQP timing chart, must produce PPAP-ready evidence, and lives under IATF 16949 audit scrutiny. If you can show your participants exactly how their DMADV outputs map onto these existing artefacts, DFSS stops being “extra work” and becomes “the engineering that strengthens our existing system”. That single framing shift is the most valuable thing this module gives you.

1. The big picture — IATF, APQP, PPAP at a glance

Before going into detail, get the layering straight. Three things sit on top of each other:

Layer	What it is	Who issues it
IATF 16949	The automotive quality management system standard. Adds automotive-specific requirements on top of ISO 9001. Yazaki Pune must hold this certification to supply OEMs.	International Automotive Task Force (IATF)
APQP 3rd Edition (2024)	The methodology for running a new product development program in a disciplined, phase-gated way. A core tool referenced by IATF 16949.	AIAG (Automotive Industry Action Group)
PPAP 4th Edition (2006)	The deliverable at the end of APQP — the package of 18 documents the supplier submits to the customer to gain approval for serial production.	AIAG

The simplest way to keep them straight

IATF 16949 is the “what” (what must be in your QMS). APQP is the “how” (how you develop a part). PPAP is the “show” (how you prove the part is ready to ship). All three are referenced in every Tier-1 customer-supplier conversation.

IATF 16949 — current edition: 1st (2016), Sanctioned Interpretations live APQP — 3rd Ed (March 2024) replaces 2nd Ed (2008) PPAP — 4th Ed (2006), still current Control Plan — 1st Ed (2024), now decoupled from APQP

2. APQP 3rd Edition — the 5 phases and what’s new

APQP is the master timing/methodology framework for any new product launch. Five phases, gated transitions, multiple deliverables per phase.

Plan & Define Program

Customer voice, design goals, reliability & quality goals

Product Design & Development

DFMEA, DVP&R, prototypes, drawings, specifications

Process Design & Development

PFMEA, process flow, tooling, work instructions

Product & Process Validation

Run @ rate, PV samples, MSA, capability studies, PPAP

Feedback & Corrective Action

Safe launch, post-SOP monitoring, lessons learned

2.1 What changed in the 3rd Edition (2024) — and why your cohort will notice +

The 2nd Edition dated from 2008. The 3rd Edition was released March 2024 with mandatory implementation by GM and Stellantis as of Sept 2024, and Ford by Dec 2024. Your participants have lived through this transition very recently — knowing the changes earns instant credibility.

Change	Why it was added
Gated review system (Gate 0 through end)	Phases now have explicit entry/exit gates with checklists. Project cannot advance past a gate without leadership review. Replaces informal phase transitions.
APQP Program Metrics	New dashboard/scorecard for tracking program health phase-by-phase. Defines metrics for cost, timing, quality.
Risk Assessment & Mitigation Plan	A formal risk register at program kickoff (Gate 0) — feeds into FMEA but is broader (commercial, supply-chain, regulatory risks).
Control Plan decoupled into separate manual	Control Plan is now Control Plan 1st Edition — a standalone document. Allows it to be updated independently of APQP.
Change Management section	Formal process for handling form/fit/function changes during APQP up to PPAP approval. Change Management Checklist (Appendix A-8).
“Safe Launch” requirement	Production Control Plan must include a Safe Launch period — tighter controls during initial production, then transition to normal controls once stability is proven.
Stronger supplier sourcing emphasis	Sub-supplier selection and qualification now explicit. Reflects that a Tier-1’s quality is hostage to its Tier-2s.
Updated terminology aligning with AIAG-VDA FMEA	Cross-references the 2019 FMEA Handbook — replaces older AIAG 4th Ed FMEA language.

Why this matters for DMADV

The new gated approach is structurally similar to DMADV phase gates. You can credibly say in the room: “APQP 3rd Edition just adopted the gate-review philosophy that DFSS has always had. The two methodologies are now even more naturally aligned.” This is a real intellectual point your senior participants will appreciate.

3. Gate management & APQP metrics

The gated approach is the most visible difference from the 2nd Edition. Each gate is a formal review with defined entry criteria, deliverables, and management sign-off.

Gate	Transition	Typical entry deliverables
Gate 0	Program initiation	Risk Factors Checklist, customer input, sourcing decision, business case, draft timing plan
Gate 1	End of Phase 1 → start of Phase 2	Reliability/quality goals, preliminary BoM, design goals, special characteristics list
Gate 2	End of Phase 2 → start of Phase 3	DFMEA, DVP&R, design records, prototype build plan, drawings released
Gate 3	End of Phase 3 → start of Phase 4	PFMEA, process flow, draft Control Plan, MSA plan, packaging spec
Gate 4	End of Phase 4 → SOP	PPAP approved, run-at-rate verified, capability demonstrated, Safe Launch plan

Instructor pattern

Ask your senior participants — particularly the GM-SD Coordination, the AGM-CDDC, and the SGM-EI — which gates their programs typically struggle to clear. The pattern is almost always Gate 2 (DFMEA quality) and Gate 4 (capability demonstration). This becomes a natural bridge to why DFSS is the answer: DMADV’s Analyze and Design phases strengthen DFMEA; Verify strengthens capability.

The DFSS-APQP gate alignment

DMADV gate reviews and APQP gate reviews can — and should — be the same review. Treating them as separate is double work. A good DFSS program at a Tier-1 doesn’t add gates; it adds rigour to the existing ones.

4. Phase 1 — Plan & Define Program

This is the “before design begins” phase. The team agrees on what’s being built, for whom, by when, against what targets.

Key deliverables

Voice of customer (VOC) — customer expectations, complaints history, warranty data
Business plan & marketing strategy
Product / process benchmark data
Product / process assumptions
Product reliability studies (from existing products / similar programs)
Customer inputs (engineering specs, packaging, customer-specific requirements)
Design goals (translating VOC into engineering targets)
Reliability & quality goals
Preliminary Bill of Materials (BoM)
Preliminary Process Flow Chart
Preliminary list of Special Characteristics — safety, regulatory, key product/process
Product Assurance Plan
Management Support & Sponsorship

Phase 1 ↔ DMADV Define + Measure

Almost everything in Phase 1 is DMADV Define and the start of Measure. VOC, QFD inputs, reliability goals, and the Special Characteristics list are produced here in either framework — they are the same artefacts seen through different lenses. A DMADV team and an APQP team doing Phase 1 should produce one unified output, not two.

5. Phase 2 — Product Design and Development

The design itself takes shape here. For a Tier-1 like Yazaki, this is where most engineering effort lives.

Key deliverables

DFMEA (per AIAG-VDA 2019 — see Module 3)
Design for Manufacturability & Assembly (DFMA)
Design Verification Plan and Report (DVP&R)
Design Reviews — formal, with cross-functional team
Prototype build & Control Plan
Engineering drawings (released)
Engineering specifications
Material specifications
Drawing & specification changes (controlled change process)
New equipment, tooling, facilities requirements
Special Product & Process Characteristics finalised
Gages / testing equipment requirements
Team feasibility commitment & management support

Phase 2 ↔ DMADV Analyze + Design

The DMADV Analyze (concept selection, P-diagram, robust design) and Design (tolerance design, design optimisation) phases produce content that directly populates the DFMEA, DVP&R, and design specifications. This is the densest overlap between DFSS and APQP.

6. Phase 3 — Process Design and Development

How the product will be built. For Yazaki, this is where the harness layout-board design, crimping process design, SMT line setup, and quality gates are defined.

Key deliverables

Packaging standards & specifications
Product/Process Quality System Review
Process Flow Chart (final)
Floor Plan Layout
Characteristics Matrix (linking product characteristics to process operations)
PFMEA (per AIAG-VDA 2019)
Pre-Launch Control Plan — tighter controls for first production runs
Process Instructions / Work Instructions
Measurement Systems Analysis plan
Preliminary Process Capability Study Plan
Management Support

The DFMEA → PFMEA handoff

DFMEA failure causes that are process-induced (e.g., insufficient crimp height) must flow into PFMEA as failure modes. This handoff happens between Phase 2 and Phase 3. Weak handoff = weak PFMEA. Trace this connection in any DMADV project you facilitate.

7. Phase 4 — Product & Process Validation

This is the proof. The product is built on production tooling, at production rate, by production operators — and then evaluated against every requirement.

Key deliverables

Significant Production Run (per PPAP requirements: 1–8 hours, minimum 300 consecutive parts, on production equipment, at production rate)
Measurement Systems Analysis (MSA) — Gauge R&R, bias, linearity, stability
Preliminary Process Capability Study — Ppk values demonstrating capability
Production Part Approval (PPAP submission)
Production Validation Testing (DVP&R execution complete)
Packaging evaluation
Production Control Plan (final)
Quality Planning Sign-Off & Management Support

Phase 4 ↔ DMADV Verify

DMADV Verify is dominantly Phase 4. The acceleration tests (Module 2), DVP&R execution, reliability demonstration, and MSA all happen here. PPAP is the closing artefact of both methodologies.

8. Phase 5 — Feedback, Assessment & Corrective Action

The “after SOP” phase. Product is in production; outputs are evaluated; lessons feed back into the next program.

Key deliverables

Safe Launch period — tighter inspection & monitoring for first weeks/months
Reduced variation (continuous improvement)
Customer satisfaction monitoring
Delivery & service quality monitoring
Lessons learned & best-practice capture

Why “Safe Launch” matters strategically

Most field-failure escapes happen in the first ~3 months of production — before the process has reached steady-state. The 3rd Edition makes Safe Launch a required Control Plan element specifically to catch escapes before they propagate to warranty claims. Senior teams should treat Safe Launch as part of the program plan, not as an afterthought.

9. The Control Plan — now its own standalone manual

Until 2024, the Control Plan was an appendix of the APQP manual. The 3rd Edition decoupled it into Control Plan 1st Edition. This signals its importance and allows it to be updated independently as systems evolve.

What a Control Plan does

The Control Plan documents — for each process operation — the characteristics being controlled, the specifications, the measurement method, the sampling plan, and the reaction plan if results go out of spec.

Column (typical)	Content
Part / Process	Specific part number, operation
Machine / Device / Tool	What equipment is used
Characteristic — Product	Dimension, feature, attribute
Characteristic — Process	Speed, temperature, pressure, torque
Special Characteristic Classification	SC, CC, KPC, KCC (customer-specific symbols)
Product/Process Specification & Tolerance	From drawing
Evaluation/Measurement Technique	Gauge, vision system, hi-pot tester, etc.
Sample Size & Frequency	n / hour, 100%, every shift, etc.
Control Method	SPC chart, error-proofing (poka-yoke), checklist
Reaction Plan	What to do if out of spec — stop, segregate, escalate

Three flavours of Control Plan

Prototype: covers dimensional measurements, material/performance tests during early build.
Pre-Launch: for the period after prototype and before normal production — typically tighter controls.
Production: the steady-state Control Plan used in serial production. Includes the Safe Launch period at the start.

10. PPAP — the 18 elements explained

PPAP is the deliverable that converts “we developed the part” into “the customer formally approved the part for production.” Without an approved PPAP warrant, no serial shipments. The 4th Edition (2006) defines 18 elements — listed below.

ELEMENT 01

Design Records

Released drawings (ballooned), specifications, design records. Every feature mapped to dimensional results.

ELEMENT 02

Authorized Engineering Change Documents

Any approved change notices (ECN) that altered the design after release.

ELEMENT 03

Customer Engineering Approval

Where required by customer — formal sign-off on the design.

ELEMENT 04

Design FMEA (DFMEA)

Required if supplier is design-responsible. Per AIAG-VDA 2019. Module 3 covers this in detail.

ELEMENT 05

Process Flow Diagram

Visual of the manufacturing process — every operation, inspection, transport, storage.

ELEMENT 06

Process FMEA (PFMEA)

Per AIAG-VDA 2019. Must be consistent with DFMEA and Control Plan.

ELEMENT 07

Control Plan

Now governed by Control Plan 1st Edition. Production version submitted.

ELEMENT 08

Measurement System Analysis (MSA)

Gauge R&R studies on the gauges used for production measurement.

ELEMENT 09

Dimensional Results

Measured results from sample parts against every drawing requirement.

ELEMENT 10

Material / Performance Test Results

Material certifications + performance test data (DVP&R results).

ELEMENT 11

Initial Process Study (Ppk)

Process capability indices for special / key characteristics. Typically Ppk > 1.67 required.

ELEMENT 12

Qualified Laboratory Documentation

Evidence that testing labs (internal or external) are accredited (e.g., ISO/IEC 17025).

ELEMENT 13

Appearance Approval Report (AAR)

For parts with appearance requirements (colour, grain, texture). Rare for Yazaki internal harness components; relevant for visible parts.

ELEMENT 14

Sample Production Parts

Physical sample parts from the significant production run, identified and traceable.

ELEMENT 15

Master Sample

A retained reference sample (signed, dated, controlled).

ELEMENT 16

Checking Aids

Fixtures, gauges, templates used to check the part. Maintained for the life of the part.

ELEMENT 17

Customer-Specific Requirements (CSRs)

Compliance records to OEM-specific PPAP rules (each OEM has its own).

ELEMENT 18

Part Submission Warrant (PSW)

The cover document — signed by supplier, approved by customer. NO PARTS SHIP without an approved PSW. Includes IMDS materials reporting status.

The Yazaki-relevant truth

For a Tier-1 like Yazaki, Elements 4 (DFMEA), 6 (PFMEA), 7 (Control Plan), 11 (Ppk), and 18 (PSW) are typically the highest-scrutiny elements. Weaknesses in any of these can block PPAP approval and delay program launch — translating directly to revenue impact. DFSS rigour focused on these elements pays back the most.

11. PPAP submission levels (1–5)

Not every PPAP submission requires all 18 elements physically delivered to the customer. The customer specifies a level based on risk.

Lowest

PSW only. Other elements retained at supplier.

Low

PSW + product samples + limited supporting data.

Standard

PSW + product samples + complete supporting data. The most common level for Tier-1 submissions.

Variable

PSW + as specified by customer (custom subset of elements).

Full

PSW + product samples + complete data, all reviewed at supplier site.

Yazaki context

For most Yazaki Tier-1 work, Level 3 PPAP is the default. New programs, safety-relevant parts, and major design changes typically require Level 3 with full evidence. The full 18-element package is prepared regardless of submission level — the level only determines what is physically sent to the customer.

12. IATF 16949 Section 8.3 — Design & Development

IATF 16949 is built on ISO 9001:2015. Section 8.3 covers “Design and Development of Products and Services.” For a Tier-1 like Yazaki, this section governs almost everything DFSS does.

12.1 What 8.3 requires (high level) +

Sub-clause	Requirement
8.3.1	General — establish, implement, maintain a design and development process
8.3.2 Planning	Plan stages, controls, verification, validation, responsibilities. This is where APQP lives.
8.3.3 Inputs	Functional, performance, statutory/regulatory, safety, environmental requirements. VOC and CSR live here.
8.3.4 Controls	Reviews at planned stages, verification, validation, change control. Gate reviews live here.
8.3.5 Outputs	Drawings, specifications, monitoring & measurement requirements, acceptance criteria. DFMEA, DVP&R, Control Plan outputs live here.
8.3.6 Changes	Document changes, review effects, approve changes. Engineering change process lives here.

The IATF supplemental clauses (the automotive-specific bit)

IATF 16949 adds automotive-specific sub-clauses on top of ISO 9001’s 8.3, including 8.3.2.1 (design and development planning — supplemental), 8.3.3.3 (special characteristics), 8.3.4.4 (product approval process — references PPAP), 8.3.5.2 (manufacturing process design output). These are the hooks where DFSS evidence lives during an IATF audit.

Why this matters for instructor credibility

When a participant says “our customer audits our DFMEA against IATF 8.3.5.2”, you should be able to nod and follow. You don’t need to recite the clauses — you need to recognise them and know they’re the audit framework that makes DFMEA quality non-optional. Cite them once in the program and the room knows you understand their world.

13. Customer-Specific Requirements (CSRs)

IATF 16949 and APQP/PPAP are the baseline. On top, every OEM imposes its own Customer-Specific Requirements. CSRs are mandatory and override more general rules.

OEM (illustrative)	Typical CSR-specific things
Tata Motors	Tata-specific PPAP format, special characteristic symbols, supplier portal submission
Mahindra & Mahindra	Mahindra Engineering Standards (MES), specific test specifications, supplier scorecard rules
Maruti Suzuki / Suzuki	SQAM (Supplier Quality Assurance Manual), specific FMEA rating tables
Stellantis	Stellantis CSR for IATF — additional 8.3 requirements, eAPQP, SQA-specific portals
Ford	Q1 supplier rating, FAR (Field Action Reporting), Manufacturing Site Assessment
GM	BIQS (Built In Quality Supply Base), GM-specific PPAP forms
Toyota	Toyota-specific design review (DR) approach, layered audits, hourly capability monitoring

The CSR trap

Many quality issues at Tier-1s come from forgetting that the OEM’s CSR overrides the AIAG default. If a participant says “PPAP requires X” but their customer requires Y, the customer wins. Always ask: “What does the CSR for this customer say?” This question alone signals deep industry literacy.

14. The DMADV ↔ APQP ↔ PPAP map

This is the single most useful artefact in this module. Memorise it.

DMADV Phase	APQP Phase	Key Outputs (also PPAP Elements)
Define	Phase 1 (Plan & Define)	Project charter, VOC, CTQ tree, Design Goals, Reliability Goals, Special Characteristics
Measure	Phase 1 + early Phase 2	QFD Level 1, CTQ measurement plan, baseline data, BoM, preliminary characteristics matrix
Analyze	Phase 2 (Product Design & Dev)	Concept selection (Pugh), DFMEA (Element 4), P-diagram, robust design parameters, design records
Design	Phase 2 + early Phase 3	Detailed design, tolerance design, Design Verification Plan (DVP&R), drawings released, Process Flow (Element 5), PFMEA (Element 6) begins
Verify	Phase 3 + Phase 4	ALT execution, MSA (Element 8), Initial Process Study Ppk (Element 11), Control Plan (Element 7), full DVP&R results, PPAP submission (Element 18 PSW)
(Post-Verify monitoring)	Phase 5 (Feedback & Corrective Action)	Safe Launch monitoring, field data, lessons learned, next-cycle DFSS inputs

The one-slide message for your participants

DMADV doesn’t replace APQP. It strengthens the engineering rigour inside it. Every DFSS tool produces evidence that flows into APQP gates and PPAP elements. If a participant runs a DMADV project that doesn’t produce APQP/PPAP-ready evidence, the project is detached from the business. Make this point visible on Day 1.

15. Instructor facilitation by function

Function	APQP/PPAP angle that lands
GM — SD Coordination / Project Management	This is their world. They live in APQP timing charts and PPAP submissions. Treat them as the gate-management subject expert.
WH (LV/HV)	Phase 2 (DFMEA) and Phase 3 (PFMEA) are where harness design lives. DVP&R per OEM spec is their daily concern.
Testing Center	Owns Phase 4 (Product & Process Validation). MSA, capability studies, DVP&R execution.
CDDC — Connectors / JB / BMS / PDU	Phase 2 design rigour. For HV products, Phase 4 capability and 100% Hi-Pot testing dominate. CSR-driven validation matrix.
EI — AR HUD PM / System Eng Lead	Software-bearing products bring ASPICE on top of APQP. Software lifecycle and PPAP intersect at IMDS, change management, and CSR.
EI — Mech / Sensor designers	Phase 2 design rigour; design records and DVP&R per OEM spec.
Shared Service — Thermal/EMI/CFD	Their simulation outputs feed Phase 2 DFMEA evidence. Often appear in PPAP Element 10 (Material/Performance Test Results).
Shared Service — Advance Materials	Material certifications (IMDS, REACH, RoHS) feed Element 17 (CSR) and Element 1 (Design Records).
Shared Service — Data Mgmt / Budget	APQP Program Metrics dashboards — new in 3rd Edition. They could become the program-metrics champion.
Innovation Cell / Tech Assistant	Lessons-learned capture (Phase 5) and future-program input. Less daily APQP, more strategic.
AGM — CDDC / SGM — EI	Senior-most. They sign PPAP warrants and approve gate exits. Engage them on gate-review effectiveness and program-metrics dashboards.

The one question to plant on the wall for all 9 days

Alongside the architectural question from Module 1, plant this APQP question: “At what APQP gate does this DMADV project deliver value, and which PPAP element does it strengthen?” Forcing every team to answer this anchors DFSS in their existing business reality.

Instructor self-check

Ten questions covering APQP 3rd Edition, PPAP 4th Edition, and IATF 16949 in the design context.

Q1. A participant says, “We submitted our PPAP last week.” Which artefact is the formal cover document and the actual approval gate?

A. The DFMEA

B. The Control Plan

C. The Part Submission Warrant (PSW) — Element 18

D. The IMDS report

Correct — PSW is the document signed by the supplier and approved by the customer. Without an approved PSW, no production parts ship.

Q2. The APQP 3rd Edition (2024) introduced which of the following as a significant change from the 2nd Edition?

A. Replaced PPAP with a new submission process

B. Formal gate management with Gate 0 to final gate, APQP Program Metrics, and decoupled Control Plan into its own manual

C. Eliminated the DFMEA requirement

D. Replaced the 5 phases with 7 phases

Correct — the 3rd Edition’s headline changes are gated review, metrics dashboards, change management formalisation, Safe Launch, and the Control Plan becoming its own standalone manual.

Q3. DMADV’s “Verify” phase most directly maps to which APQP phase(s)?

A. Phase 1 only

B. Phase 2 only

C. Phase 5 only

D. Phase 3 (PFMEA, Control Plan) and Phase 4 (MSA, capability, PPAP)

Correct — Verify produces evidence that feeds Phase 3 and Phase 4 artefacts, culminating in the PPAP submission.

Q4. The “Safe Launch” requirement added in APQP 3rd Edition refers to:

A. A period of tighter inspection and monitoring during initial production until process stability is proven

B. A safety meeting before SOP

C. A new PPAP element

D. ISO 26262 functional safety analysis

Correct — Safe Launch is the practice of running tighter controls in the Production Control Plan for the first weeks/months of serial production to catch escapes before they propagate.

Q5. PPAP Level 3 (the most common for Tier-1 work) requires:

A. PSW only

B. PSW + product samples + complete supporting data submitted to customer

C. Customer site visit only

D. No supporting documentation

Correct — Level 3 is the standard “full documentation” level for most Tier-1 production parts.

Q6. A team complains “we passed our DFMEA review but failed Gate 4 capability.” What’s the most likely root cause?

A. The DFMEA was wrong

B. The customer changed their mind

C. Weak handoff from DFMEA failure causes into PFMEA / Control Plan / capability study design — the design wasn’t aligned to be manufacturable to its capability target

D. Gate 4 doesn’t exist

Correct — Gate 4 failures usually trace back to a Phase 2-3 handoff weakness. Process-induced failure causes from DFMEA must drive PFMEA design and Control Plan rigour.

Q7. Customer-Specific Requirements (CSRs) relative to AIAG default rules are:

A. Optional add-ons that can be ignored

B. Mandatory; CSRs override more general AIAG defaults where they differ

C. Only applied to safety parts

D. The same across all OEMs

Correct — CSRs are customer-specific and mandatory. Each OEM has its own. Confusing the AIAG default with the CSR is a common Tier-1 error.

Q8. IATF 16949 Section 8.3 governs:

A. Financial reporting

B. Human resources

C. Calibration only

D. Design and development of products and services — the clause inside which APQP, DFMEA, DVP&R, and PPAP all sit during an IATF audit

Correct — 8.3 is the audit framework for everything DFSS does. Knowing this single reference signals industry literacy.

Q9. The Control Plan is now:

A. A standalone 1st Edition manual (2024), decoupled from APQP to allow independent updates

B. Still an appendix of the APQP manual

C. Replaced by the PFMEA

D. Eliminated

Correct — one of the headline 3rd Edition changes. Control Plan becoming its own manual signals its strategic importance.

Q10. The single most powerful question to plant on the wall for the 9-day program, alongside the architectural question from Module 1, is:

A. “What is the unit cost?”

B. “Who is the project sponsor?”

C. “At what APQP gate does this DMADV project deliver value, and which PPAP element does it strengthen?”

D. “What is the colour of the product?”

Correct — this question anchors every DMADV project to the real business cycle. Projects that can’t answer it are detached from the company’s value chain.
