In the first part of the book, the counseling concept is presented along with its theoretical connections to pragmatism and systemic thinking. Building on this, a multidimensional process model of supervision is described. A model for the diagnosis and indication of various profession-related counseling formats, such as supervision, organizational consulting, and mediation, is specified in the concept "Counseling about Counseling" and sets standards for exploration and clarification of assignments. Additionally, the differences and opportunities for cooperation are clarified. The history of the supervision format, as well as its development and differentiation over the past decades, concludes the first part of the book. The second part of the book provides insight into practice. Over 100 methods are presented in a uniform system and sorted by phases in the counseling process as well as by special aspects and topics.
