Supplier Performance & Compliance Auditing

Service summary

A structured review of an established supplier’s performance against agreed requirements over a defined period. The audit considers delivery, quality and response records alongside the controls intended to maintain consistent supply.

The resulting evidence supports periodic supplier reviews and proportionate escalation. Performance conclusions distinguish recurring weaknesses from isolated events and recognise the limitations of the records and samples examined.

Key objectives

• Evaluate sustained contractual performance
• Examine recurring delivery or quality issues
• Assess corrective action effectiveness
• Support continued-approval reviews

Methodology

Historical performance is reconciled with operating evidence and selected corrective actions to evaluate sustained compliance rather than a single-day snapshot.

• Agree the review period, performance measures and supplier obligations.
• Analyse delivery records, complaints, rejects and previous review outcomes.
• Select recurring issues and representative orders for detailed tracing.
• Examine operational controls linked to the selected performance indicators.
• Interview relevant personnel and test corrective action implementation.
• Assess trends, repeat failures and remaining evidence gaps.
• Report findings for the buyer’s continued-approval and escalation decisions.
