The system describes the sequence and the structured intertwining of our processes. The control loop featuring the phases "Leadership and Strategy", "Resource management", "Product Implementation" and "Measurement, Analysis and Improvement" ensures the continuous development of our business processes and enables us to felibly respond to external requests (from customers, society, suppliers). Furthermore, ZVK stands for outstandling product quality and innovation. This standard is the result of the rigorous management mentioned above that assures constant information and support, from design through to series production. In addition to highly qualified employees and the "living" ISO 9001 management system, this is based on close cooperation with testing institutes such as GHMT and TÜV Rheinland.
