Together, Continental and Schaeffler form a joint purchasing cooperation. Every two years, they nominate or confirm selected premium suppliers. One hundred and ten suppliers out of 1,200 were selected, and these were systematically appraised following defined criteria. Besides an appropriate product range and high quality, the decision-making criteria include logistics performance and global competitiveness. Of 32 nominated suppliers, six new suppliers were ultimately accepted into the "Premium Supplier Circle"; collaboration with these companies will now intensify in the areas of development and digitization.
