Supervision has undergone a remarkable development in recent decades. It established itself in many fields of work world. The very practical and application-related supervision is required to review, update and expand their knowledge and knowledge, and to achieve a scientific foundation for their practice. The necessity and attractiveness of a research-based further development of the theory and practice of supervision is seen both by the community and by scientists without their own supervision training. The frequent complaint that there is no supervision research can be put into perspective. One can currently complain rather about the lack of networking, the lack of awareness of research work and the rare discussion about findings and results. This volume addresses these circumstances and contributes to publicizing, networking and a research-friendly culture. It presents a collection of research results and research considerations by authors from a wide variety of disciplines. This reflects a differentiated understanding of research and science. The book is not only aimed at scientists and researchers, but the content and perspectives are chosen so that practitioners can also benefit from it in many ways.
