A certified organisation bases its processes and workflows on a management system. TÜV Rheinland Group checks whether the management system complied with the relevant norms and then issues a certificate.

An organisation with a quality management that has been found to fulfill the ISO Standard 9001 is entitled to call itself "ISO 9001-certified."

Customers can gain confidence in the way the organisation works. An ISO 9001-certified organisation must constantly check and improve customer satisfaction. Customers of a certified organisation can work on the assumption that they will be taken seriously if they have problems or complaints and will receive effective assistance.

TÜV carries out renewed audits of management systems at regular intervals, therby ensuring that all employees do in fact abide by the processes and that the management system is adapted to take any corporate changes into account.
