We conduct a so-called hotspot analysis in order to find out exactly where the points of highest risk are located in the supply chain – this is one of the first steps towards a precise code of conduct. These factors can differ from sector to sector. TÜV Rheinland’s auditors check the status of the suppliers by means of a questionnaire that can be based on the customer’s specific standards or international ones. Our auditors know from experience how to organize investigations to monitor the weak points.
