Welcome back. In the last lesson, you built a controlled standards register: the source-control layer that identifies whether a regulation, standard, customer requirement, or core tool applies, which revision governs, and what evidence it calls for.
This lesson turns that register into a working development system. You will map quality-system standards, customer overlays, and automotive core tools to a simulated set of development gates for the assumption-based EDV projects. The central discipline is to keep their roles distinct: ISO 9001 and IATF 16949 define expectations for the management system; APQP organizes product-quality planning; FMEA and Control Plans manage risk and process control; PPAP provides a customer-facing production approval submission; and CSRs add customer-specific obligations.
Start with the correct mental model: layers, not synonyms
In automotive programs, documents are often casually grouped under “quality requirements.” That is convenient shorthand, but it produces weak engineering decisions. These items interact, yet none can substitute for another.
| Item | What it is | Its main job | What it is not |
|---|---|---|---|
| ISO 9001 | General quality-management-system standard | Defines disciplined organizational processes for planning, documented information, competence, control of nonconformity, improvement, and more | A component test specification or an APQP timing plan |
| IATF 16949 | Automotive QMS standard used with ISO 9001 | Adds automotive expectations, including stronger attention to product safety, supplier development, contingency, traceability, change management, and manufacturing-process control | A PPAP package or a customer engineering specification |
| Customer-specific requirements (CSRs) | Customer-owned supplemental requirements | Specify how a particular customer expects relevant QMS, core-tool, submission, approval, portal, and record requirements to be handled | A universal requirement applicable to every OEM |
| APQP | Product-quality planning framework | Organizes cross-functional work, timing, risks, deliverables, reviews, and readiness decisions across a program | A certification standard or evidence that a part is approved for production |
| AIAG-VDA FMEA | Risk-analysis methodology | Identifies functions, failure chains, controls, and actions to improve a design or process before failures reach the customer | A final inspection plan or a PPAP approval |
| Control Plan | Controlled manufacturing-process document | States what characteristics and process parameters are controlled, by whom, how often, with what method, and what happens when results are unacceptable | An FMEA, drawing, or one-time launch report |
| PPAP | Production-part approval process and evidence submission | Demonstrates that production-intent parts and processes meet agreed design-record and specification requirements | The entire APQP process or a substitute for ongoing process control |
A useful way to think about the relationship is this:
- ISO 9001 and IATF 16949 establish the organization’s operating discipline.
- CSRs overlay specific customer expectations onto that discipline.
- APQP provides the program roadmap and gate structure.
- FMEA identifies and prioritizes risk within that roadmap.
- Control Plans convert relevant manufacturing risks and requirements into recurring controls.
- PPAP assembles selected evidence to support a customer decision on production readiness.
The APQP flowchart below shows why confusion occurs: its phases contain deliverables from several different tools. The flowchart is an integration view, not proof that all the tools are the same thing.

APQP phases and management gates
APQP is normally described through five overlapping phases:
- Plan and define the program.
- Product design and development.
- Process design and development.
- Product and process validation.
- Feedback, assessment, and corrective action.
A company gate is the management decision point placed at a meaningful program boundary. It asks whether the team has sufficient evidence, resources, and risk control to proceed. A gate is therefore not merely a meeting, and it is not a ceremonial signature after the engineering work is complete.
The APQP third-edition gated-management example uses six gates because it separates initial concept approval from detailed program approval. Your simulated EDV program will use the same practical convention:
| Simulated gate | Primary decision | APQP emphasis |
|---|---|---|
| G0 — Concept initiation | Should the team authorize planning work and resource the concept? | Before or at the start of Phase 1 |
| G1 — Program approval | Are requirements, timing, risks, sourcing assumptions, and quality planning sufficient to proceed? | End of Phase 1 |
| G2 — Design feasibility | Can the proposed design meet requirements and be manufactured, assembled, and serviced? | End of Phase 2 |
| G3 — Process feasibility | Is the proposed manufacturing system capable of controlling the design? | End of Phase 3 |
| G4 — Launch readiness | Is production-intent product and process evidence sufficient for launch and PPAP disposition? | End of Phase 4 |
| G5 — Feedback and stabilization | Has performance justified transition from enhanced launch controls to normal production controls? | Phase 5 |
These are simulated internal gate names, not asserted Rivian or Amazon procedures. In a real program, the customer’s product-development system, statement of work, and CSR may prescribe different names, dates, approval authorities, or submission portals.
[PDF] APQP-Third-Edition-2.pdf
Read the “Gated Management” appendix in the APQP manual. It provides a useful reference model for turning the APQP phases into management decisions with documented results, rather than treating APQP as a checklist completed at the end of the program.
In Appendix B, “Gated Management” on pp. 69–71, read the narrative introducing the six-gate framework and the full gate-summary table. Begin at the gated-management explanation. Focus on the distinction between a gate decision and the detailed evidence reviewed at that gate, especially the way incomplete items require an action plan rather than being hidden.
The key point from this model is that gate deliverables are not isolated. Outputs from one phase become inputs to the next. For example, a design requirement and a preliminary special characteristic identified at G1 shape the DFMEA at G2. The DFMEA then informs the process PFMEA and Control Plan developed at G3.
Map each framework to the gates
ISO 9001 and IATF 16949: the system operating throughout every gate
Neither ISO 9001 nor IATF 16949 belongs only at G0 or G4. They govern how the organization controls its work across the whole program.
For the simulated EDV program, evidence of IATF-aligned behavior should be visible at every gate:
| Gate | Quality-system behavior expected |
|---|---|
| G0 | Defined roles, competence needs, document-control approach, initial risk assessment, controlled assumptions |
| G1 | Reviewed customer inputs, controlled requirements baseline, supplier-interface responsibilities, planned design and development controls |
| G2 | Design-review records, verification status, controlled design outputs, feasibility assessment, traceable approvals |
| G3 | Supplier and manufacturing-process readiness, documented process controls, measurement planning, escalation of open issues |
| G4 | Production-intent evidence, nonconformance handling, traceability, customer submission records, launch controls |
| G5 | Performance monitoring, corrective action, lessons learned, controlled updates to FMEAs and Control Plans |
Thus, do not write “IATF complete” as a G4 deliverable. A stronger G4 statement would be:
“The release package demonstrates that the simulated QMS has controlled the applicable design, supplier, configuration, validation, nonconformance, and approval records through the launch-readiness baseline.”
That wording acknowledges that IATF-aligned discipline is demonstrated by the controlled records and decisions made across the program.
Customer-specific requirements: the gate-specific overlay
A CSR can affect any gate. It may require a particular FMEA method, specific special-characteristic symbols, customer approval of selected documents, a prescribed PPAP level, an electronic submission portal, defined safe-launch exit criteria, or retention periods.
However, never infer an EDV customer requirement from another OEM’s CSR. Use public OEM documents to understand how CSRs work, but label the actual EDV requirement as:
- approved customer requirement, if you have a controlled customer source; or
- program assumption pending customer confirmation, if you do not.
The Ford CSR is a useful illustration of a genuine customer overlay. It shows that customer expectations may require acceptance of FMEAs and Control Plans, prescribe traceability between special characteristics and risk records, and require a particular PPAP approach. Those details are Ford-specific, not transferable by default to another customer.
[PDF] Ford Motor Company Customer-Specific Requirements - IATF
Read these excerpts as an example of how an OEM CSR supplements the broader IATF and AIAG framework. The purpose is not to adopt Ford requirements for the simulated EDV program, but to recognize the additional approvals, formats, and traceability a real customer may impose.
In Section 8.3.2.1, “Design and development planning — supplemental,” on pp. 23–25, read from the discussion of FMEA and Control Plan development through the discussion of special-characteristic traceability. Start at the customer-specific control requirements. Then, in Section 8.3.4.4, “Product approval process,” on p. 28, review the PPAP paragraph. Focus on what the customer adds: required acceptance, submission route, and change-related resubmission expectations.
For your simulated project records, create a CSR-SIM-001 entry in the standards register. It can define the course’s required deliverable formats and evidence, but it must be clearly identified as a simulated program requirement, not a real Rivian or Amazon CSR.
APQP is the gate framework; PPAP is a late-stage evidence submission
APQP starts early, when information is incomplete. It is deliberately preventive: it brings customer needs, requirements, risks, feasibility, supplier readiness, test planning, and manufacturing planning into view before production problems become expensive.
PPAP normally occurs much later, around product and process validation. It is the formal evidence package that supports a production approval decision for a defined production-intent configuration.
Why Advanced Product Quality Planning (APQP)?
Watch this short portion of PMC Videos’ “Why Advanced Product Quality Planning (APQP)?” for a concise visual distinction between APQP’s phases and PPAP’s role as an output supported by APQP work.
Watch the APQP phases to identify the five phases and their overlap. Then watch PPAP within APQP, focusing on the idea that PPAP is evidence generated from preceding development work. Treat any example production quantity mentioned by the presenter as illustrative; the applicable customer requirement controls actual run quantity and PPAP expectations.
The relationship can be expressed precisely:
| Statement | Accurate? | Why |
|---|---|---|
| “APQP is a structured planning framework.” | Yes | It coordinates activities and deliverables across development and launch. |
| “PPAP is one output of APQP.” | Yes | It uses evidence generated through design, process development, validation, and production-intent trials. |
| “PPAP replaces APQP once approved.” | No | APQP feedback, production control, corrective action, and change management continue after launch. |
| “A PPAP is automatically required for every engineering change.” | Not necessarily | The applicable customer PPAP and change-notification requirements determine whether resubmission is required. |
| “An approved PPAP means the FMEA and Control Plan can never change.” | No | Both are living records; changes need controlled review, evidence, and customer notification or approval where required. |
At G4, a strong gate decision does not say, “All paperwork is done.” It says something closer to:
“The production-intent configuration, manufacturing process, measurement systems, validation evidence, special-characteristic controls, and customer-required PPAP evidence have been reviewed. The customer disposition is approved, interim approved, rejected, not required, or pending.”
That distinction matters. A supplier can have a technically complete internal package while still awaiting customer approval. Conversely, an interim customer approval does not make unresolved process risk disappear; it requires clear containment, ownership, and timing.
FMEA and Control Plans: connected records with different responsibilities
The AIAG-VDA FMEA method is built around understanding intended functions before analyzing failure. It supports prevention and risk optimization, rather than treating risk analysis as a static form to be completed for a gate.
For a design-responsible component such as the simulated high-voltage ECU housing:
- The DFMEA examines design functions and potential design failure mechanisms.
- The PFMEA examines manufacturing-process functions and potential process failure mechanisms.
- The Control Plan defines the recurring controls used during prototype, pre-launch, safe-launch, or production conditions.
The records should be linked, but they should not be copied mechanically into one another.
| Record | Typical gate maturity | Main content |
|---|---|---|
| Preliminary DFMEA scope and known-risk review | G1 | Intended functions, historic risks, new technology, early risk assumptions |
| Part DFMEA | G2 | Product structure, functions, failure effects, causes, prevention and detection controls, action-priority decisions |
| Process flow | G3 | End-to-end manufacturing and inspection sequence |
| PFMEA | G3 | Process-step functions, process failure chains, controls, and improvement actions |
| Prototype Control Plan | G2 | Measurements and tests needed to learn from prototype builds |
| Pre-launch Control Plan | G3 | Enhanced temporary controls before the manufacturing process is fully validated |
| Production Control Plan | G4 | Sustained production controls, methods, frequency, reaction plans, and ownership |
| Revised FMEAs and Control Plans | G5 and changes | Learning from production performance, corrective actions, supplier issues, and engineering changes |
A practical traceability chain for the ECU enclosure could look like this:
- The requirement baseline states that the installed enclosure must maintain its specified ingress performance under the approved test conditions.
- The DFMEA identifies loss of sealing as a potential functional failure and evaluates causes such as inadequate gasket compression, distorted sealing land, or incomplete fastener clamp load.
- The team identifies potential special characteristics only where justified by the approved requirement and risk analysis. A sealing-land geometry or gasket-compression-related feature might become a candidate.
- The PFMEA examines manufacturing causes such as warped molded parts, flash on the sealing land, incorrect gasket installation, or an incorrect fastener-tightening program.
- The pre-launch and production Control Plans define the actual prevention and detection controls, including the characteristic, specification, measurement method, sample frequency, responsible role, reaction plan, and record.
- PPAP evidence draws on the approved design record, material evidence, dimensional results, validation records, process flow, PFMEA, Control Plan, measurement-system studies, capability evidence, and required customer documentation.
The Ford CSR provides an important general lesson here: a foundation FMEA can preserve organizational knowledge from prior injection-molding programs, but it does not replace the part-specific FMEA. A foundation FMEA might include generic risks such as short shots, sink, warpage, gate vestige, or incorrect resin drying. The ECU-housing DFMEA and PFMEA must still address the actual geometry, sealing concept, material, tooling strategy, and functional risks of this component.
The simulated EDV gate-and-deliverable map
The following map is the operating model for the rest of the course. It applies to the ECU housing first, then will be adapted for the door trim and HVAC outlet projects.
G0 — Concept initiation
Decision: authorize planning and assign accountable owners.
| Deliverable | Primary framework | Controlled purpose |
|---|---|---|
| Assumptions log with confidence levels | ISO/IATF-aligned documented information | Separates public facts, engineering assumptions, and unknowns |
| Standards and source register | ISO/IATF-aligned document control; CSR input | Identifies applicable sources and source owners |
| Preliminary risk register | APQP | Makes program, technology, capacity, supplier, packaging, and timing risks visible |
| APQP timing plan and responsibility matrix | APQP | Defines planned deliverables, owners, and gate dates |
| Initial supplier and interface strategy | IATF-aligned supplier management | Assigns ownership for components, tooling, tests, and interfaces |
Not expected at G0: finished CAD, a completed DFMEA, a Control Plan, or PPAP evidence.
G1 — Program approval
Decision: approve the planned quality path and requirements baseline sufficiently to begin detailed design.
| Deliverable | Primary framework | Controlled purpose |
|---|---|---|
| Approved requirements baseline and RTM | ISO/IATF design planning; customer inputs | Links each measurable requirement to verification and evidence |
| Product Assurance Plan or equivalent | APQP | Consolidates quality, reliability, technology, and program risks |
| Preliminary EBOM and manufacturing concept | APQP; PLM control | Makes product structure and likely process visible |
| Preliminary special-characteristic candidates | APQP; customer overlay where applicable | Flags characteristics needing deliberate risk and control analysis |
| Initial validation strategy | APQP; customer requirements | Establishes intended test ownership, timing, and configuration needs |
| G1 decision log and action tracker | ISO/IATF-aligned documented information | Captures approval boundaries, open items, owners, and due dates |
Not expected at G1: a customer PPAP approval. APQP planning is underway; production process capability cannot yet be demonstrated.
G2 — Design feasibility
Decision: confirm that the design is technically feasible and can progress into supplier process development and prototype verification.
| Deliverable | Primary framework | Controlled purpose |
|---|---|---|
| Controlled CAD baseline, drawings in development, EBOM revision | ISO/IATF design outputs; PLM | Defines the design configuration assessed at the gate |
| DFMEA and action plan | AIAG-VDA FMEA | Identifies design risks and tracks risk-reduction actions |
| DVP&R or equivalent verification plan | APQP; customer engineering requirements | Plans analyses, tests, inspections, and demonstrations against the RTM |
| DFM, DFA, serviceability, and moldability review | APQP | Confirms the design is compatible with intended manufacture and service |
| Prototype build plan and Prototype Control Plan | APQP; Control Plan methodology | Defines what will be controlled and learned during prototype manufacture |
| Design-review record and team feasibility commitment | APQP; ISO/IATF design controls | Captures cross-functional technical decision and remaining risks |
At G2, the DFMEA should already influence the product. If the team discovers that a rib arrangement risks sealing-land distortion, simply recording the issue in the DFMEA is insufficient. The action should drive a controlled CAD revision, a new analysis or test entry, and a re-review of the affected requirement.
G3 — Process feasibility
Decision: confirm that the planned production process can realize the design and control its critical risks.
| Deliverable | Primary framework | Controlled purpose |
|---|---|---|
| Manufacturing process-flow diagram | APQP | Defines the full process sequence used for PFMEA and Control Plan development |
| PFMEA | AIAG-VDA FMEA | Identifies manufacturing failure mechanisms, controls, and improvement actions |
| Pre-launch Control Plan | Control Plan methodology | Provides enhanced controls while the process is maturing |
| Process instructions and inspection instructions | IATF-aligned operational control | Translates approved controls into executable shop-floor work |
| Measurement-system analysis plan | MSA core tool | Ensures needed gauges and tests will be suitable for decisions |
| Preliminary capability-study plan | SPC and PPAP support | Defines how process capability will be evaluated |
| Tooling, test-equipment, packaging, and supplier readiness plan | APQP; customer overlay | Controls launch-critical readiness activities |
At this gate, the process flow, PFMEA, and Control Plan must agree. If the process flow includes resin drying, injection molding, de-gating, inspection, gasket installation, torqueing, leak testing, and packaging, the PFMEA and Control Plan must cover the relevant risks and controls at those steps. Missing steps are a traceability defect, not a minor formatting issue.
G4 — Launch readiness and PPAP disposition
Decision: determine whether production-intent evidence supports launch and the required PPAP disposition.
| Deliverable | Primary framework | Controlled purpose |
|---|---|---|
| Significant production-run record | APQP; PPAP support | Demonstrates production tooling, equipment, personnel, environment, and rate as defined by the applicable plan |
| Production validation test evidence | APQP; customer engineering requirements | Confirms production-intent product meets engineering requirements |
| Measurement-system study results | MSA | Shows that measurements used for key decisions are adequate |
| Preliminary process capability results | SPC; PPAP support | Evaluates readiness of the production process, especially for identified special characteristics |
| Production Control Plan | Control Plan methodology | Defines normal production control strategy and reaction plans |
| PPAP submission index and customer disposition | PPAP; CSR | Records submission level, configuration, evidence, exceptions, and approval state |
| Quality-planning sign-off and launch risk register | APQP | Documents the management decision, residual risk, containment, and closure plan |
The exact contents and approval path of PPAP are customer-specific. Your simulated project will prepare a PPAP-readiness package, not claim a real customer production approval.
G5 — Feedback, assessment, and corrective action
Decision: determine whether the process is stable enough to exit enhanced launch controls and how learning will be retained.
| Deliverable | Primary framework | Controlled purpose |
|---|---|---|
| Safe-launch or enhanced-containment exit evidence | CSR and Control Plan, when required | Demonstrates that temporary additional controls can be reduced under defined criteria |
| Production capability and performance records | SPC; APQP feedback | Shows whether variation and quality performance are improving |
| Corrective-action records | ISO/IATF nonconformance and improvement | Documents containment, root cause, corrective action, and effectiveness checks |
| Updated DFMEA, PFMEA, and Control Plan | AIAG-VDA FMEA; Control Plan | Captures new knowledge and prevents recurrence |
| Lessons-learned record and foundation-FMEA review | APQP; organizational knowledge | Transfers learning to future parts and programs |
| ECO or change-impact assessment | IATF-aligned change control; PPAP/CSR as applicable | Evaluates the effect of a change on design, process, evidence, and approvals |
Make every gate a controlled PLM event
Because PLM will be a continuous theme in your three projects, each gate should produce more than a slide deck. Create a controlled gate package with:
- gate identifier, such as
G2-ECU-DESIGN-FEASIBILITY; - product configuration baseline, including CAD version, drawing revision, EBOM revision, and requirements baseline;
- list of reviewed deliverables with revision identifiers;
- red, yellow, or green status for each deliverable;
- explicit decision: approved, conditionally approved, deferred, or rejected;
- open actions with owners, due dates, and escalation route;
- named approvers and dated approval evidence;
- links to related risks, deviations, supplier issues, and ECOs.
A gate may be conditionally approved only when the remaining work is visible, owned, time-bound, and does not undermine a requirement that must be satisfied before proceeding. A “green” gate with unrecorded high-risk actions is worse than a transparent “yellow” gate: it corrupts the program baseline and makes later traceability unreliable.
For the simulated ECU project, create a workbook or database called:
EDV_APQP_Gate_and_Deliverable_Matrix_RevA
Use one row per gate deliverable. Include these columns:
| Field | Example |
|---|---|
| Gate ID | G2 |
| Deliverable ID | DFMEA-ECU-001 |
| Deliverable name | ECU enclosure DFMEA |
| Framework | AIAG-VDA FMEA |
| Owner | Mechanical Design Lead |
| Required input baseline | REQ-ECU-B01, CAD-ECU-BASE-V03 |
| Required decision | Design feasibility approved or actions assigned |
| Evidence link | Controlled file location or Onshape document/version link |
| Status | Green, yellow, red, or not applicable |
| Approval reference | Decision-log item and approver |
| Open-action reference | ACT-G2-014 |
| Change impact | RTM, CAD, drawings, DVP&R, PFMEA, Control Plan, PPAP readiness |
Keep the framework field explicit. It prevents a later reviewer from mistaking an APQP gate-summary item for a PPAP requirement, or treating a CSR-required customer acceptance as merely an internal design-review action.
A change scenario: why the distinctions matter
Assume an ECU-housing supplier reports warpage near the gasket sealing land after the initial production trial.
A weak response would be: “Update the FMEA and resubmit PPAP.”
A controlled response separates the roles:
-
Containment and issue definition
Record the affected lots, part revision, tool condition, measurement method, and observed sealing-land variation. Apply the simulated nonconformance and supplier-issue procedure. -
Risk analysis
Update the PFMEA to reflect the process mechanism causing warpage. Review the DFMEA because the process variation may threaten an intended sealing function. Assess whether the existing design is robust enough to manufacturing variation. -
Control strategy
Revise the pre-launch or production Control Plan if the control method, frequency, reaction plan, or process parameter needs to change. Confirm that the required gauge or fixture is suitable through the MSA plan or study. -
Engineering and configuration impact
If geometry, material, gate location, molding conditions, tooling, or gasket compression changes, open an ECO. Link revised CAD, drawing, BOM, mold-flow evidence, DVP&R entries, and affected requirements. -
Customer and PPAP impact
Consult the actual applicable customer change-notification and PPAP requirements. The change may require notification, partial submission, full resubmission, customer approval, or a documented determination that resubmission is not required. -
APQP and gate impact
Reassess the G3 or G4 readiness decision. A prior gate may need reapproval because evidence that supported it is no longer valid for the revised configuration.
In this scenario, FMEA identifies and manages risk, the Control Plan governs recurring control, PPAP addresses customer production approval evidence, APQP organizes the recovery work, and ISO/IATF-aligned processes ensure the records, nonconformance, supplier communication, approvals, and change history are controlled.
Key takeaways
You should now be able to distinguish the roles of the main automotive quality frameworks:
- ISO 9001 and IATF 16949 govern the quality-management system across the full lifecycle.
- CSRs are customer-specific overlays that can add gate criteria, formats, approvals, and submission requirements.
- APQP structures the product-quality planning work and management gates.
- AIAG-VDA FMEA provides the method for analyzing and reducing design and process risk.
- Control Plans define how production and launch conditions are controlled in practice.
- PPAP is a production-approval submission supported by evidence produced through APQP; it is not a replacement for APQP or ongoing quality control.
- Every gate needs a controlled configuration baseline, decision record, evidence index, risk status, and action tracker.
Next, you will configure an IATF-aligned simulated project record that makes these ideas operational: design responsibility, supplier interfaces, traceability, documented information, validation, nonconformance, and engineering-change control.
