If you supply to any major automotive OEM or Tier 1 — Maruti, Tata, Mahindra, Stellantis, Toyota, or their Tier 1 suppliers — IATF 16949 is a supply chain requirement. Without it, you cannot be added to their approved vendor list. If you already supply and your customer has issued a development notice, you are on a clock.

Your company is implementing IATF 16949 and you need to understand your role. IATF 16949 means every production stage follows a documented control plan, every job is traceable from customer order to despatch, and every in-process inspection result is recorded. Your job is to follow the control plan and record what you actually measured.
Control plan
Every step documented with what to measure and how
First-off
First piece of every run approved before bulk production
Traceable
Every part traceable to its production records
Quick reference. IATF 16949:2016 — published by IATF (International Automotive Task Force). Supplements ISO 9001:2015 (both required simultaneously). Key automotive core tools: APQP, PPAP, FMEA (AIAG-VDA 2019), Control Plans, MSA, SPC. Customer-Specific Requirements (CSRs) are mandatory additions — published by each OEM and Tier 1.

IATF 16949 is published by the International Automotive Task Force — a joint initiative of major automotive OEM industry groups from Europe, North America, and Japan. It combines the requirements of earlier regional automotive quality standards (VDA 6.1, AVSQ, EAQF, QS-9000) into a single global standard, supplementing ISO 9001.

What’s on this page
01 —What it isUnderstanding IATF 16949
The global automotive supply chain quality standard — required by every major OEM.
IATF 16949 is the quality management system standard for the automotive supply chain. It is published by the International Automotive Task Force (IATF) and supplements ISO 9001 — both standards are always implemented and certified together. You cannot hold IATF 16949 without also holding ISO 9001.
The standard requires all the elements of ISO 9001 plus automotive-specific requirements: APQP (Advanced Product Quality Planning), PPAP (Production Part Approval Process), FMEA (Failure Mode and Effects Analysis), Control Plans, MSA (Measurement System Analysis), and SPC (Statistical Process Control).
On top of the base standard, every OEM and major Tier 1 publishes its own Customer-Specific Requirements (CSRs). CSRs are mandatory additions — if you supply Maruti, you must also comply with Maruti's CSRs. Ignoring CSRs is one of the most common nonconformances found in IATF audits.
IATF 16949 can only be certified by IATF-sanctioned CBs. Unlike ISO 9001, not all NABCB-accredited CBs are authorised to certify IATF 16949. Always verify your CB is on the IATF-sanctioned list at iatfglobaloversight.org before engaging them.
👥 Illustrative case — details changed for confidentiality
The business
Precision machined components manufacturer Chennai · 95 employees, Tier 2 supplier to Tier 1 automotive
The trigger
Their Tier 1 customer issued a supplier development notice requiring IATF 16949 certification within 12 months or loss of preferred supplier status.
The challenge
During gap analysis, their production records were the biggest gap. Jobs moved through the shop floor but there was no stage-wise digital record. First-off approvals, in-process inspections, and control plan compliance were tracked on paper forms — inconsistently.
Where Clicarity came in
They had been using Clicarity for job tracking. Their quality consultant configured each production stage with the control plan parameters as custom fields. From that point, every job captured: operator, equipment, first-off approval, in-process measurement result, and sign-off. When jobs split into mating part pairs, each was tracked through CMM inspection independently. When they rejoined at final release, the complete inspection record of both parts was preserved.
The result
IATF 16949 certification achieved within the 12-month deadline. Preferred supplier status retained.
IATF requires traceability at every stage. Clicarity gave us that traceability without having to build a separate documentation system.
02 —Who needs itIs it right for you?
Do you actually need it? Honest answer.
✓ You need it
Tier 1 suppliers to any major automotive OEM in India
Tier 2 suppliers whose Tier 1 customers require it
Manufacturers of automotive components, sub-assemblies, or safety-critical parts
∼ Check with your customer
Heat treaters, platers, and sub-contractors to the automotive chain (often ISO 9001 suffices — confirm with your Tier 1)
Tooling and equipment suppliers to automotive manufacturers
— ISO 9001 is sufficient
Non-automotive manufacturers
Raw material suppliers (steel, chemicals) — check with your specific customer
Check your customer's CSRs. If you have received a supplier development notice, request your customer's Customer-Specific Requirements document immediately. CSR compliance is verified at every IATF audit.
03 —What it requiresWhat is checked
What an IATF 16949 auditor checks — beyond ISO 9001.
1
Control plans for all production processes
A control plan for every manufacturing process specifying what to measure, how to measure it, the control method, and the reaction plan if the limit is exceeded.
E.g. CNC turning stage: characteristic = diameter, specification = drawing tolerance, measurement method = CMM, frequency = first-off + 1 per hour.Most common gap: Control plan exists but does not match actual production practice. Auditors walk the floor and compare.
2
PPAP for all customer parts
Production Part Approval Process documentation for every customer part, signed off by the customer before production begins.
E.g. PPAP includes: design records, FMEA, control plan, measurement system analysis, initial process capability study, and customer sign-off.Most common gap: PPAP submitted but not all elements completed. Level of PPAP (1-5) not confirmed with customer.
3
FMEA for all products and processes
Design FMEA (DFMEA) and Process FMEA (PFMEA) per AIAG-VDA 2019 methodology.
E.g. PFMEA for CNC machining: failure modes, effects, causes, current controls, and action priority rating.
4
Customer-Specific Requirements compliance
Evidence that all CSRs from every customer have been reviewed, documented, and implemented.
E.g. A CSR matrix showing each requirement mapped to the relevant internal procedure or control.Most common gap: CSRs reviewed at initial certification and never updated when the customer issues a new version.
5
Measurement System Analysis (MSA)
Gauge R&R studies for key measurement systems. Evidence that measurement variation is understood and controlled.
E.g. Annual gauge R&R for CMM and key hand gauges. Results within acceptable limits.
6
Statistical Process Control (SPC) for critical characteristics
SPC charts maintained for special or critical characteristics as defined in the control plan.
E.g. Cpk tracked for key dimensions. Control charts maintained at the relevant workstation.
7
Traceability from customer order to despatch
Every part traceable through every production stage to the original customer order, drawing revision, and raw material heat/lot number.
E.g. Part number → Job number → Stage records → Material heat number → Supplier certificate.
What inspectors really check
They will pull a random finished part and ask: "Trace this to its raw material and show me the stage records." Then: "Show me the control plan for this operation and show me the last SPC chart." They will also interview shop floor operators on control plan requirements.

04 —Official bodyWho certifies in India
Who issues this in India — and how to verify it.
IATF 16949 certification can only be issued by IATF-sanctioned certification bodies. This is a stricter requirement than ISO 9001 — not all NABCB-accredited CBs are authorised for IATF 16949.
Always verify your CB on the IATF list first. The IATF Global Oversight website at iatfglobaloversight.org maintains the definitive list of sanctioned CBs. Verify before engaging. An IATF 16949 certificate from a non-sanctioned CB is not valid and will not be accepted by OEMs.
IATF Global Oversight — Sanctioned CB list
Verify your CB is IATF-sanctioned here before engaging them.
IATF 16949 requires ISO 9001:2015 simultaneously. If not already certified, start with ISO 9001.

Customer-Specific Requirements are the most underestimated part of IATF 16949. Many companies implement the base standard thoroughly and then discover their CSR matrix has gaps only when the auditor asks for it. Get CSR documents from every customer before starting implementation.
06 —Find certified companiesHow to verify
How to find and verify certified organisations.
IATF 16949 certified organisations can be verified through IATF Global Oversight. To verify whether a specific automotive supplier is currently certified, use the IATF search tool.
How to verify: To confirm whether any organisation holds a current IATF 16949 certification, use the official register. Verify the issuing CB's accreditation at nabcb.qci.org.in.
Verify your CB is IATF-sanctioned before doing anything else
Go to iatfglobaloversight.org and check the sanctioned CB list. An IATF 16949 certificate from a non-sanctioned CB is not valid. Confirm before engaging any CB.

Implement the 5 core tools before focusing on documentation
APQP, PPAP, FMEA, Control Plans, MSA, SPC are the technical heart of IATF 16949. Auditors examine these in detail. Documentation without working core tools does not pass.
Good records are the foundation. A process tracker builds them automatically.
Clicarity — Live Job Process Tracker & Bottleneck Identifier
Clicarity doesn't implement your APQP or write your control plans. It tracks your production jobs — and when your control plan steps are mapped to stages, the process records are created as part of daily work.
IATF 16949 requires production part traceability, control plan compliance evidence, and in-process monitoring records. In Clicarity, every job is traceable from customer PO to despatch. Each stage has custom fields aligned to your control plan: operator, equipment number, measurement result, first-off approval, and sign-off. When mating parts or component pairs are split into sub-jobs, each is tracked independently through its own inspection steps. When they rejoin, the complete traceability record of every component is preserved in one job record.
Customer PO number and part number captured at job creation — every stage update is traceable back to the specific customer order and drawing revision.
Control plan steps mapped as production stages with custom fields — in-process measurement results, first-off approval dropdowns, and operator attribution captured as part of normal work.
When a job splits into mating component pairs (drive gear, driven gear), each is tracked through CMM inspection independently. When they rejoin, the full inspection record of both parts is preserved in one traceable job.
Clicarity shows stage-wise rejection rates — by stage, by operator, by equipment — which is the kind of process performance data IATF's manufacturing process monitoring requirements ask for.
