AIAG core tools · APQP, Control Plan, PPAP, FMEA, MSA and SPC
Automotive core tools implementation and training for launches your customer can approve.
The core tools are reference manuals published by AIAG, two of them jointly with VDA. They are not a certifiable standard and no certificate exists for them. Your automotive customers expect to see them working on your parts: in the launch plan, the risk analysis, the gauges, the control charts and the approval package. Sterling's expert and experienced consultants apply them with your engineers on live part numbers, in 60+ countries. We help our clients put it into practice and prove it.
- Fixed scope, one proposal: consulting, Effivity software, Sterling Academy access and internal auditor training, as applicable to your standard, in one proposal
- A team of expert and experienced automotive quality consultants, applying the core tools across sectors and countries since 2003
- The Sterling Promise: 100% on-time completion, 100% success, 8,100+ client engagements. Sterling does not certify; your customer approves the parts and, where you hold IATF 16949, an accredited certification body audits how the tools are used
8,100+ client engagements in 60+ countries.
Why automotive suppliers choose Sterling
What it is
What are the AIAG core tools and what are they used for?
The Automotive Industry Action Group (AIAG) groups six methods as its Quality Core Tools: Advanced Product Quality Planning (APQP), the Control Plan, the Production Part Approval Process (PPAP), Failure Mode and Effects Analysis (FMEA), Measurement Systems Analysis (MSA) and Statistical Process Control (SPC). Each is published as a reference manual. FMEA and, since July 2026, SPC are joint publications with the German Association of the Automotive Industry (VDA).
Together they carry a part from quotation to stable production. APQP plans the launch, FMEA finds what could fail, the Control Plan fixes how each characteristic is controlled, MSA proves the gauges can be trusted, SPC watches the process in production and PPAP packages the evidence for the customer's approval. They are methods, not a management system; what gets judged is the part, the file behind it and whether the methods were used properly.
Current editions. AIAG lists APQP 3rd edition with a standalone Control Plan 1st edition, PPAP 4th edition, MSA 4th edition and the AIAG & VDA FMEA Handbook. The AIAG & VDA SPC Manual was published in July 2026. Each customer's specific requirements decide which editions apply to your parts, so confirm them before you change a template. IATF 16949 core tools: how the standard uses them
Who it is for
Who needs the automotive core tools?
Any business that designs or makes parts, materials or assemblies for vehicle manufacturers, or for their suppliers, meets the core tools sooner or later. They reach you through a purchase order, a supplier manual or an audit finding, usually from one of four directions:
- A customer nominates you for a new part. The sourcing letter or supplier manual asks for an APQP timing plan, FMEAs, a control plan and a PPAP submission by a set date.
- A tender or supplier survey scores your launch discipline. Buyers ask how you plan a launch, qualify gauges and monitor special characteristics.
- Your IATF 16949 audit is coming. The standard's own interpretations name design FMEA among design outputs and address measurement system analysis, and auditors trace the tools on real parts.
- A group company or new plant must launch the group's way. A parent or sister site already works to the manuals and wants the new operation aligned.
The benefit, fewer launch surprises, depends on engineers using the tools while they design, not writing them afterwards.
Requirements
What do the automotive core tools require?
The six tools below are the set AIAG names. There is no clause structure to certify against: each manual describes a method, and your customers' specific requirements say which manual, edition, forms and submission rules apply. The list gives the purpose of each tool in plain language; detailed rules sit in the licensed manuals.
- APQP, Advanced Product Quality Planning: a structured plan that takes a new or changed part from concept through validation to launch, with a cross-functional team and gated reviews.
- Control Plan: the written description of how each product and process characteristic is controlled, measured and reacted to, now a manual of its own.
- PPAP, Production Part Approval Process: the evidence package showing that production parts from the real process meet every customer requirement, submitted for the customer's approval.
- FMEA, Failure Mode and Effects Analysis: design and process risk analysis that finds potential failures, their effects and causes, and drives actions before they reach the customer, set out in the joint AIAG & VDA Handbook.
- MSA, Measurement Systems Analysis: studies that show whether gauges and inspection methods give data good enough to make decisions on.
- SPC, Statistical Process Control: charts and capability studies that show whether the process is stable and capable, and signal when it drifts.
What does useful core tools evidence look like?
A launch timing plan with gate reviews held on time, a process flow, a PFMEA and control plan that match each other and the shop floor, gauge studies for the characteristics that matter, capability results from a real production run and a PPAP warrant the customer has signed. We build these on your own parts, keep them under document control in Effivity and link each file to the others it depends on.
Implementation
How do you implement the core tools and prove it?
Because there is no certificate, proof comes from two places: your customer's approval of your parts and, if you hold IATF 16949, the certification body's audit of how the tools are used. Sterling prepares you for both; neither decision is ours.
- 01Collect each customer's requirements.Supplier manuals, specific requirements, submission levels, forms and the editions of each manual they expect, gathered in one register.
- 02Gap analysis: compare practice with the manuals.Sample recent launches, FMEAs, control plans, gauge studies and approval files; agree what to fix, who owns it and by when.
- 03Train on a live part.Engineers, quality and production staff learn each tool while building the real files for a current or upcoming part number.
- 04Review before the customer does.An internal check of the approval package and linked files, run as the customer or auditor would, with every finding closed with evidence.
- 05Submit, launch and keep the files alive.PPAP submission and customer approval, then FMEAs, control plans and capability kept current through changes, complaints and audits.
Check the route before you sign. Nobody can certify your company to the core tools; an offer of a "core tools certificate" for an organisation is not what your customer is asking for. AIAG runs training and exams for individuals, which record personal learning, not a company approval. Ask your customer which manuals and editions apply, and confirm that any IATF 16949 certification body is recognised by IATF. IATF 16949 certification consulting

Timeline
How long does core tools implementation take?
Training and the first set of working files usually run in parallel with a real part, so the pace follows that part's gates, the availability of your engineers and how long production trials and capability runs take. Expect months, not weeks, typically two to four for a first part family, before a complete file is ready for submission.
| Phase | What determines the pace |
|---|---|
| Requirements and gap analysis | Access to customer documents, recent launch files and the engineers who wrote them |
| Training and file building | Team availability and the design and process changes the FMEAs call for |
| Studies and trials | Gauge availability, trial runs and enough production data for capability |
| Submission and approval | The customer's review time and any resubmissions |

Effivity · ISO and GRC software, included in every engagement
How Effivity helps you control, automate and simplify core tools evidence.
Every Sterling core tools engagement includes Effivity, the ISO and GRC automation platform built by the Sterling group and used in 50+ countries. Your consultant sets up the workspace within the agreed scope, so FMEAs and control plans sit under document control, gauges carry their calibration records, training shows who is competent in each tool and complaints feed corrective action that updates the risk analysis. Sterling consulting clients get their Effivity subscription included with the engagement, at no additional cost.
Launch actions and reviews
Actions from each gate review tracked with owners and dates, so an overdue task shows up before the gate, not at it.
Controlled documents
Control plans, process flows and work instructions with versions and approvals, so the shop floor works to the current issue only.
Supplier evaluations
Sub-tier supplier approvals and evaluations kept current, because your own submission depends on theirs.
Risks and corrective action
Complaints and internal failures investigated to root cause, with the action that updates the FMEA recorded and closed.
Calibration
Gauge register, calibration due dates and results in one place, ready to link to the measurement studies that rely on them.
Monitoring and KPIs
Process and quality indicators on dashboards, with out-of-limit results raised as nonconformities rather than lost in a spreadsheet.
Training records
Who has been trained in each tool, linked to Sterling Academy, so competence evidence is current at every audit.
Your own forms and workflows
Customer forms, fields and approval flows adapted without code, with customer requirements tracked to the processes they touch.
What this means at the audit
An auditor or customer engineer picks a part and asks for its FMEA, control plan, gauge calibration and training records. In Effivity each one is a screen with dates, owners and approvals attached, and a change to one shows which others need review. Under Sustain™ the same workspace carries every later launch.

FAQs
Frequently asked questions about the AIAG core tools
Can a company get AIAG core tools certification?
No. The core tools are reference manuals and no body certifies an organisation against them. Evidence of use comes from customer part approvals and, for IATF 16949 sites, the certification audit; individual employees can take AIAG's own training and exams.
Are the core tools mandatory for IATF 16949?
In practice, yes. IATF 16949 expects methods such as FMEA, measurement system analysis and statistical tools, and its interpretations name design FMEA among design outputs. Which manuals and editions you follow is set by each customer's specific requirements.
Do we have to redo old FMEAs in the AIAG & VDA format?
Only if your customer requires it. Your customers' requirements decide whether and when existing FMEAs move to the joint method; where a move is needed, we plan the conversion part family by part family, starting with new or changing parts.
Do the core tools apply outside the automotive industry?
Yes, by choice or by contract. Aerospace has its own APQP and PPAP requirements in SAE AS9145, and suppliers in other sectors adopt FMEA, MSA and SPC because the methods prevent defects wherever parts are made.
Can Sterling train our engineers on APQP and PPAP?
Yes. Training is delivered in workshops while your team builds the files for a current part, supported by preferential Sterling Academy access, so people leave with a completed file rather than notes.
