Our success in business is dependent to a significant extent on our suppliers. The quality of materials and reliability in the supply chain are absolutely essential for us as an infrastructure operator. We achieve this through partnership-based relationships on a level playing field: our goal is to create value for both sides through open communication, flexible and transparent processes and collaboration on innovative developments. When it comes to supplier management, we believe in a structured supplier-onboarding and contract-management process along with an ongoing evaluation of supplier performance.
