Audit Services & Supplier Assessment

An audit is a structured snapshot of a company’s current actual process performance and quality capability. It provides a fact-based assessment of compliance, efficiency, and risk exposure across production and supply chain processes. Depending on the objective, different audit formats are applied – from supplier qualification to process and system audits. The QMatrix Group supports OEMs, Tier-1 and industrial manufacturers with independent, structured and practice-oriented audit services based on international automotive and quality standards.

Potential analysis - Supplier Risk & Capability Assessment

It provides critical insights into:

This analysis is essential during:

• New supplier selection
