Restoring IATF 16949 Certification Across a Multi-Plant Tier-1 Supplier

Background:

A Tier-1 automotive supplier supporting several global OEMs experienced widespread quality breakdowns across multiple manufacturing plants following a series of mergers and acquisitions. Leadership turnover and fragmented operating practices weakened the organization’s quality management system, resulting in chronic quality failures and escalating OEM concern.

Following intervention from the International Automotive Oversight Bureau (IAOB), multiple plants lost their IATF 16949 certification. OEM scrutiny intensified, supplier risk status increased, and new business awards were suspended pending recertification.

Crossover Solutions was engaged to stabilize the quality system, rebuild plant-level execution discipline, and lead the organization through IATF recertification.

Critical Issues:

The evaluation identified several systemic breakdowns affecting quality performance:

• Loss of IATF 16949 certification at multiple plants
• OEM Red Supplier status indicating elevated operational risk
• Frequent CS2 escalations tied to recurring quality failures
• New program launches and business awards placed on hold
• Fragmented quality leadership following multiple acquisitions
• Inconsistent execution of core Quality Management System disciplines

Without rapid intervention, the organization faced escalating customer risk and continued erosion of operational credibility.

Our Approach:

Crossover Solutions embedded experienced quality leadership within plant operations to stabilize execution and rebuild the Quality Management System.

The work focused on restoring operational discipline, rebuilding compliant processes, and preparing the organization to successfully complete the IATF certification process.

Key Actions:

• Conducted comprehensive IATF 16949 gap assessments and internal audits across both plants
• Validated process capability and measurement systems through SPC and MSA analysis
• Rebuilt the Quality Management System architecture, procedures, and documentation
• Embedded XO quality leadership to drive execution, coaching, and accountability
• Implemented compliant operating practices across engineering, production, materials, maintenance, and document control
• Trained plant leadership and operational teams on certification requirements and audit readiness

Results:

The recovery effort restored the organization’s quality management system and enabled successful completion of the full IATF audit process.

Plant operations transitioned from unstable quality performance to disciplined execution aligned with IATF standards.

Both plants successfully completed recertification and restored their standing with OEM customers.

• Manufacturing plants successfully recertified to IATF 16949
• OEM supplier risk status removed following certification
• New business awards and product launches resumed
