By adopting Microsoft Dynamics 365 Field Service, ZF's after-sales service department in Germany has realized the unification of information management. The system integrates functions such as parts management, service scheduling and maintenance record tracking, thereby optimizing the after-sales service process, improving service efficiency and reducing human error. In addition, the automation features of the system ensure that customer problems can be quickly responded to and effectively resolved. The centralized management of information also provides more accurate data support for decision making, which improves overall operational efficiency and customer satisfaction.
