Customer Management includes all business processes that are focused on the analysis, acquisition, retention and development of customers. The research of the Chair is dealing with issues of both customer rating and customer research such as customer satisfaction, customer retention, customer value or customer controlling, with questions of relationship marketing and its tools (customer clubs, cards, events etc.) as well as with the organizational implementation (process management, structural basis), particularly with the Key Account Management. Our European Network for Key Account Management (EN KAM) serves the purpose of bringing together the research in Key Account Management.
