Customer-specific requirements.
Each OEM publishes CSRs supplementary to IATF 16949. Stellantis, Ford, GM, VW, Hyundai-Kia, Tata, Mahindra, and Maruti Suzuki each have their own — and these shift year on year.

Automotive — OEM-ready quality, end to end.

Automotive supply is a world of its own. IATF 16949 is effectively mandatory for direct production supply; customer-specific requirements from every OEM customer add supplementary expectations; core tools discipline — APQP, PPAP, FMEA, MSA, SPC — is the daily operating language of the plant; and the IATF scheme's strict oversight means an audit non-conformity can be materially more consequential than in other sectors.
Crescent supports tier 1 and tier 2 suppliers through initial IATF certification, scope extensions as new product lines come on board, transition audits when standard revisions land, and day-to-day coaching for quality functions carrying the weight of multiple OEM customer audits. We do not write PPAP submissions for our clients; we help the client build the discipline to produce them themselves, because the PPAP has to stand up over a product life-cycle where we are long gone.

engagements distinct.
Core tools as daily discipline.
APQP, PPAP, FMEA, MSA, SPC move from training courses to the way the plant actually runs. Paper-level compliance is quickly detected at IATF audit.
Sub-tier cascade.
Sub-tier supplier development — the predominant source of field defects — is materially stricter than under ISO 9001. Escalation discipline matters here.
Layered process audits.
LPAs bring supervisors and management into the gemba. Done honestly, they are the single most transformative element of the standard.

No. IATF 16949 is applied in conjunction with ISO 9001; all ISO 9001 requirements are implicit. Most suppliers drop separate ISO 9001 certification, unless a non-automotive customer specifically requires a 9001 certificate in addition.
The IATF scheme's formal scope covers production parts, service parts, and accessories intended for installation on or in the vehicle. Pure aftermarket production frequently sits outside strict scope, though many OEMs extend the requirement anyway.
EV OEMs layer specific requirements on top of IATF 16949 — battery safety, traceability, cybersecurity (ISO/SAE 21434) — that are driving substantial evolution of automotive QMS practice.
