Strengthening Supply Chain Assurance Through Vendor Assessments

In today’s complex and fast-moving industrial environment, supply chain assurance is more important than ever. For businesses managing global operations, ensuring suppliers consistently deliver safe, compliant products and services—on time and to specification—is essential. Robust vendor assessments reduce costly delays, prevent critical failures, and safeguard your business from reputational and regulatory risks.

At SQS, we specialise in helping companies strengthen their supply chain compliance and performance through tailored supplier audits and risk-based supplier evaluation frameworks.

What Are Vendor Assessments?

Also known as supplier audits, vendor assessments are a structured method of evaluating a supplier’s capability, reliability, and alignment with your operational and strategic objectives. These assessments provide deep insight into your supplier’s quality, delivery and ethical standards.

They’re a crucial step for any organisation seeking to enhance supplier due diligence, reduce risk, and build a resilient global supply chain.

Purpose and Key Components of Supplier Audits

The goal of a vendor assessment programme is to ensure that potential and existing suppliers can meet your requirements around:

• Product and service quality

• Timeliness and reliability

• Competitive pricing and value

• Health, safety, and environmental compliance

• Capacity for long-term collaboration

Core components of a supplier audit include:

• Management systems and certifications (e.g. ISO, ESG compliance)

• Operational capacity and equipment

• Health and safety controls

• Ethical and sustainability practices

• Historic performance metrics and delivery track record

By benchmarking these factors across your supply base, you improve supplier selection and streamline your supply chain risk management strategy.

Benefits of Effective Vendor Assessments

A proactive and consistent vendor assessment process brings significant value beyond basic supplier evaluation:

• Stronger supply chain resilience

• Better-informed procurement decisions

• Enhanced quality control and operational reliability

• Improved compliance with international standards

• Lowered risk of supplier failure or disruption

At SQS, we work with clients across 48 countries to implement tailored assessment programmes that support global supplier management and drive continuous improvement in quality, delivery and sustainability.

Three Key Strategies for Effective Supplier Assessment

2. Tailor assessments by risk and categoryDifferent suppliers pose different risks. We design customised vendor assessments based on risk levels, sector, geography, and regulatory requirements to ensure compliance and efficiency.

3. Benchmark across your supplier networkComparing similar vendors helps identify performance gaps and drive consistency. Our benchmarking tools improve supplier performance management and promote best practices across your supply chain.
