Christine Rupp develops opportunities for a segment-specific, value-based membership management in sports clubs. The management approach aims to help clubs successfully tackle current and pressing challenges in the sports club sector, such as attracting and retaining officials and coaches. The author describes existing scientific findings on stakeholder segmentation in nonprofit organizations, develops a multidimensional concept of member evaluation, and analyzes which members are particularly valuable and important for which sports clubs. Implications for membership management in clubs and associations emphasize the practical relevance of the work.
