Auditing production sites abroad

Globalization and international supply chains open up many opportunities for companies - at the same time, the challenges in quality management are also growing. Especially when you work with foreign production sites, one thing is crucial: trust is the basis, transparency and quality control create security.

A professional production site audit is a proven means of creating clarity: about processes, standards, management systems and working conditions. Whether for supplier selection or as part of your internal quality management - an audit helps to safeguard decisions and build sustainable partnerships.

In this article, you will find out what is important when conducting an audit abroad, what types of audit there are and a practical checklist for direct implementation.

What is a production site audit?

What are audits and what role do they play in quality management? A production site audit is a structured examination of the operational conditions of a supplier. The aim is to find out whether the supplier meets the qualitative, organizational and social requirements of your company - not just on paper, but in day-to-day operations.

An audit typically includes:

• The evaluation of the quality management system (e.g. according to ISO 9001)

• The analysis of production processes and capacities

• The review of legal, social and ethical standards

• The review of documented procedures and their implementation

Unlike a pure product inspection, an audit examines the entire organization - from goods receipt to production and delivery. The aim is to objectively assess the supplier's capabilities and create a solid basis for cooperation.

For classification:

• Audit review refers to the entire evaluation process

• Internal audits take place within the company itself

• Supplier audits involve external partners

💡 At Line Up, we regularly carry out such audits in our own network of production partners. In this way, we ensure consistent quality across all supply stages, for ourselves and our customers.

Why are audits of production sites abroad particularly important?

In practice, international audits are significantly more complex than domestic audits. Geographical distance, cultural differences and different standards make it more difficult to realistically assess production conditions from afar. The risk lies less in deliberate misconduct than in structural differences:

• Differing standards: Labor, environmental or safety standards vary around the world.

• Gaps in documentation: Many producers do not have fully digitized traceability.

• Certifications are a valuable basis: But the personal impression on site provides additional, practical insights into processes and procedures.

An audit does not serve to demonstrate mistrust - on the contrary: it creates a common basis for working in partnership at eye level. Particularly in countries with different economic conditions, it is helpful to analyze processes together and develop improvements.

Successful audits not only lead to better products, but also strengthen mutual understanding and cooperation.

An overview of the most important audit types

The requirements for audits vary depending on the industry and product. In principle, the following types of audit can be distinguished:

System audit

Evaluates the entire quality management system - from management responsibility to continuous improvement. Ideal for assessment in accordance with ISO 9001, IATF 16949 or ISO 14001.

Process audit

Detailed inspection of individual procedures or production processes - such as welding, sewing, painting or assembly.

Product audit

Quality control of the end product - are the dimensions, tolerances, material or function correct?

Social audit

Review of working conditions, occupational health and safety, social benefits and compliance with local laws (e.g. child labor, discrimination, remuneration). Relevant for CSR goals and statutory due diligence obligations.

Environmental audit

Assessment of environmental compatibility - waste management, emissions, energy efficiency.

The process of an audit review abroad

A good audit is always systematically structured. This is how you carry out an audit in a structured and efficient manner:

1. preparation

• Define objectives and scope

• Prepare audit checklist

• Request documents from the supplier

• Organize language support (e.g. interpreter)

2. on-site visit (factory tour)

• Opening meeting with the management of the production facility

• Factory tour (machines, workstations, warehouse, etc.)

• Interviews with responsible persons (production, QA)

• Inspection of documents (e.g. test plans, ISO certificates)

3. evaluation & follow-up

• Evaluation according to audit criteria

• Documentation of deviations

• Recommendations & deadlines for rectification

• Final discussion and report

Checklist: What should a production site audit include?

Use this list to prepare and carry out your audit. It can be expanded depending on the industry.

This list can be extended for specific industries or products. It is important that your assessment remains comparable and comprehensible. The checklist is also suitable for supplier evaluation in accordance with ISO 9001.

🎯 Tip: Evaluate each area using traffic light colors or points. This creates comparability between suppliers.
