Supervision is a rule-based procedure for reflecting on ongoing work processes and is used to design alternative courses of action in social, mental health and counsel professions. It is offered to social and mental health professionals to reflect on their work, their capacity as participants. In a supervision they are referred to as supervisees. The supervisor leads the supervision. He/She is a specialist in social and mental health work and as a supervisor is not involved in the work problems of the supervisees. The aim of supervision is to protect and promote the skills of the supervisees and at the same time the maintenance and development of new opportunities to work more professionally. Supervision is an integrated tool of professional social work. It promotes self-understanding and understanding of other people's professional activities in the complex field of action and stimulates the personal development of professionals as the team. (cf. Belardi 2001, p. 1863; Gaertner 1996, p. 600; Pühl 2000, p. 3; Retaiski 1997, p. 938) In social work, supervision is understood as a “secondary method”, i.e. a method that does not serve to deal directly with the clientele, but acts indirectly as "advice for the adviser" on the cooperation with the clientele (cf. Krauss 1996, p. 396).

"(Eco 2001, p. 22)
