Supervision is a function of controlling, reflecting and securing organizational processes, which can be performed by an individual (supervisor) or a group (supervision team). It includes the psychologically and group-dynamically founded consultation of the performers in their task completion and their critical examination of their own activity with the aspect of optimizing and evaluating the performance of the individual or the group. It is hoped that this will lead to higher qualification and improved professional competence of the employees. (Source: Schneider: Lexicon on Team and Teamwork)
