CQI-19 Sub-Tier Supplier Management Process Guideline

This guideline supports a common, practical approach to evaluating, selecting, developing, monitoring, and escalating sub-tier suppliers across the automotive supply chain.

Common supplier management process: Aligns the industry around a structured approach from pre-selection through performance monitoring and escalation.
Risk-based supplier evaluation: Emphasizes supplier capability, capacity, quality culture, sustainability, traceability, and pass-through characteristics. APQP / PPAP and control planning: Reinforces expectations for planning, special characteristics, PTC management, special process assessments, and production readiness. Ongoing development and escalation: Defines how suppliers should monitor, improve, and escalate performance when they identify systemic issues.

Ensure end-to-end quality and resilience across your automotive supply chain with the CQI-19-2 standard. Developed by the Automotive Industry Action Group (AIAG), the Subtier Supplier Management Process Assessment (2nd Edition) is a vital framework designed to help organizations evaluate, monitor, and improve the performance of their subtier suppliers.

What is CQI-19-2?

In the automotive industry, quality failures often originate deep within the supply chain. CQI-19-2 provides a standardized assessment tool that enables original equipment manufacturers (OEMs) and tier-one suppliers to look beyond direct suppliers and proactively manage risks across the entire multi-tier supply network.

Key Features & Focus Areas

• Comprehensive Risk Management: Identify potential vulnerabilities, capacity bottlenecks, and quality risks within subtier supply chains before they impact production.

• Structured Assessment Checklists: Utilize practical, standardized evaluation templates aligned with automotive industry best practices.

• IATF 16949 Alignment: Seamlessly integrate subtier management processes into your existing Quality Management System (QMS) requirements.

• Supplier Development: Drive continuous improvement by establishing clear performance expectations and accountability measures for subtier partners.

Benefits for Your Organization

• Minimize Disruptions: Protect your production lines from unexpected material shortages and quality defects.

• Enhance Cost Efficiency: Reduce the costs associated with scrap, rework, and emergency problem-solving caused by substandard components.

• Strengthen Transparency: Build a clearer picture of your extended supply network and foster closer collaboration with critical partners.
