Our selection and qualification process for suppliers and service providers

Suppliers and service providers are selected according to a predefined selection and qualification process.

We use a group-wide standardized questionnaire in order to obtain the necessary information about suppliers or service providers early on. To ensure that products or services meet our high standards, they are tested and sampled in further qualification steps according to strict rules. Apart from that, an audit and trial delivery can follow.

Ultimately, purchasing, quality management and specialist departments are deciding on the approval and registration of the supplier or service provider.
