Supplier Audits

Supplier audits to assess quality, processes and risks

Supplier audits create transparency regarding the quality, processes, risks and performance of suppliers. They help companies identify weaknesses at an early stage, make well-founded decisions and derive targeted improvement actions.

TopQM-Systems supports companies with Supplier Audits — from audit planning and execution through to evaluation and corrective action tracking. Depending on the industry and requirements, process audits, system audits, potential analyses or industry-specific audit methods such as VDA 6.3, VDA 6.8 or AIAG CQI audits may be relevant.

Our goal is clear: we help you assess suppliers realistically, make supply chain risks visible and follow up actions effectively — nationally and internationally.

 

Why supplier audits are important

Suppliers directly influence quality, delivery capability, delivery dates, costs and customer satisfaction. If processes at the supplier are not stable, quality requirements are not met or risks are identified too late, this can lead to complaints, delivery delays, production problems or escalations.

A professional supplier audit helps to assess these risks in a structured way. It shows whether requirements are understood, processes are under control, evidence is available and actions are implemented effectively.

Supplier audits help companies to:

  • Objectively assess supplier quality
  • Identify process risks at an early stage
  • Safeguard supplier approvals
  • Assess audit readiness and maturity level
  • Derive improvement actions
  • Prepare supplier development in a targeted way
  • Prevent escalations
  • Meet requirements from customers, standards or industry-specific methods

This makes supplier audits an important instrument in supply chain management.

 


When a supplier audit is useful

A supplier audit can be useful or required in many different situations. It is not only used for control, but also for risk assessment, qualification and sustainable improvement.

Typical reasons include:

  • Selection or approval of new suppliers
  • Assessment of existing suppliers
  • Preparation for project award or series production launch
  • Supplier qualification or requalification
  • Weak supplier performance
  • Recurring quality issues or complaints
  • Supplier escalations
  • Audit findings from customer or certification audits
  • Assessment of process capability and maturity level
  • Requirements from VDA, IATF, CQI or customer-specific specifications
  • National or international supplier assessments

TopQM-Systems supports companies in defining the purpose, scope and suitable audit method in a targeted way.

Types of supplier audits

Not every supplier audit has the same objective. Depending on the question to be answered, different audit types may be useful.

Process audit at the supplier

A process audit assesses whether processes at the supplier are carried out in a stable, effective and requirement-compliant way. The focus is on process capability, risks, interfaces, evidence, responsibilities and improvement potential.

System audit at the supplier

A system audit examines the supplier’s management system or specific system elements. It may be relevant, for example, when requirements from ISO 9001, IATF 16949 or customer-specific specifications need to be reviewed.

Potential analysis

A potential analysis can be used when selecting new suppliers or before project award. It helps assess whether a supplier is fundamentally suitable and which risks may exist before cooperation begins.

CQI or special audits

In certain industries or processes, special audit methods may be required — for example AIAG CQI audits in the automotive environment or customer-specific audit requirements.

Process audits and industry-specific audit methods

Standardised audit methods play an important role in the automotive and industrial environment. TopQM-Systems contributes experience from industry-specific requirements and audit methods.

VDA 6.3 Audit
VDA 6.3 is an established method for process audits, particularly in the automotive industry. In the supplier context, VDA 6.3 can help systematically assess process risks, maturity level and improvement potential.

VDA 6.8 Audit
VDA 6.8 addresses process-oriented requirements along the supply chain and may be relevant in the context of logistics, service and supply chain processes.

CQI-Audits
AIAG CQI requirements can play an important role for special processes or customer-specific requirements. They are particularly relevant when suppliers must meet specific automotive process requirements. Further information on meaning, application and standards can be found in the AIAG CQI Competence Center by TopQM-Systems at cqi-support.de.

It is important that these audit methods are not considered in isolation. The decisive factor is always the question the audit is intended to answer — for example supplier approval, risk assessment, process stability, escalation, supplier development or action effectiveness.

Audit planning, execution and evaluation

An effective supplier audit begins with a clear objective. Which risks need to be assessed? Which processes are in focus? Which requirements apply? Which evidence is needed? And which decision should the audit support?

TopQM-Systems supports structured planning, execution and evaluation of supplier audits.

Typical steps include:

  • Defining the audit reason, objective and scope
  • Selecting the appropriate audit method
  • Preparing the audit plan and checklists
  • Coordinating with the supplier and internal departments
  • Conducting the audit on site or remotely, where appropriate
  • Evaluating processes, evidence and risks
  • Documenting findings and non-conformities
  • Deriving actions and responsibilities
  • Preparing the final report and management information
  • Following up action implementation

This turns the supplier audit into a reliable basis for decision-making.

Action management after supplier audits

The real value of a supplier audit is created after the audit. What matters is whether findings are translated into concrete actions and implemented effectively.

TopQM-Systems supports action management after supplier audits — from prioritisation and tracking through to effectiveness review.

The focus is on:

  • Assessment and prioritisation of audit findings
  • Creation of realistic action plans
  • Definition of responsibilities and deadlines
  • Tracking of implementation
  • Escalation in the event of delays or lack of effectiveness
  • Effectiveness review of corrective actions
  • Transition into supplier development or supplier management
  • Reporting to quality, purchasing, SCM or management

This ensures that an audit does not remain a snapshot, but becomes the starting point for sustainable improvement.
