1. Executive Summary

This report presents the annual performance review of [Supplier Name] for air spring assemblies supplied to [Client Name] for commercial vehicle applications.

Overall Rating: B+ (Good Supplier – Meets Requirements)

Key Strengths:

• Consistent delivery performance (91/100)

• Effective response to quality issues

• Competitive pricing structure

Key Improvement Areas:

• Rubber-to-cord adhesion (identified in 3 PPM claims)

• Dimensional consistency on piston OD (process capability Cpk < 1.33)

• BOM documentation accuracy (identified as gap in audit)

Status: Supplier is approved for continued business. Improvement plan required (see Section 6).

2. Quality Performance (Weight: 40%)

2.1 PPM (Parts Per Million) Performance

Trend: Quality performance has improved year-over-year. PPM decreased from 385 to 312, a reduction of 19%. The supplier met the PPM target of ≤ 500.

2.2 Claim Summary (FY2026)

2.3 8D Report Closure

All 9 PPM claims have been closed with 8D reports.

Observation: The supplier has improved 8D closure time from 28 to 19 days.

3. Delivery Performance (Weight: 30%)

3.1 On-Time Delivery (OTD)

Analysis: The supplier has consistently met or exceeded the 95% target in Q3 and Q4 of FY2026.

3.2 Delivery Exceptions

Observation: Delivery exceptions decreased from 3 in Q1 to 1 in Q4, indicating improvement.

4. Cost Performance (Weight: 20%)

4.1 Cost Reduction Performance

Analysis: The supplier achieved a 1.8% cost reduction, slightly below the target of 2.0%. No supplier-initiated cost increases were requested.

4.2 Cost Reduction Initiatives (FY2026)

5. Technical Support (Weight: 10%)

5.1 Support Performance

Analysis: Technical inquiry response time improved from 38 to 26 hours, though still slightly above target (26 vs. 24). All other metrics meet targets.

5.2 Technical Issues (FY2026)

6. Audit Summary

6.1 Quality System Audit (August 2026)

Audit Observations:

1. Rubber mixing consistency: The supplier uses a batch mixer. Recent batches showed 5% variation in viscosity. The supplier has not applied SPC to the mixing process. Observation closed with corrective action.

2. Traceability: The supplier's traceability system is paper-based. The supplier cannot trace a finished air spring to a specific rubber batch without significant manual effort. Observation remains open. Corrective action required by December 2026.

3. Material certification: The supplier's material certificates are not consistently formatted. The format varies between batches, making comparison difficult. Observation closed with corrective action (completed June 2026).

7. Improvement Plan for 2027

7.1 Required Improvements (High Priority)

7.2 Recommended Improvements (Medium Priority)

8. Supplier Strengths

The following strengths were noted during the review:

1. Responsiveness: The supplier has demonstrated a commitment to resolving quality issues quickly. 8D closure time improved by 9 days.

2. Delivery reliability: The supplier has maintained OTD at 96.8% for FY2026, exceeding the target.

3. Cost competitiveness: The supplier has achieved cost reductions for two consecutive years without compromising quality.

4. Investment: The supplier has invested in new automation for piston machining, indicating a commitment to the relationship.

9. Recommendations

The Supplier Quality Engineering Team recommends:

1. Maintain the supplier's approved status. The supplier meets all key performance requirements.

2. Require implementation of the improvement plan. The supplier must implement the required improvements by the specified target dates.

3. Conduct follow-up audit in January 2027. Verify implementation of the improvement plan and closure of open audit observations.

4. Negotiate 2027 cost reduction target. The supplier has not yet submitted a 2027 cost reduction proposal. The buyer should request a target of ≥2.0% for 2027.
