We would like to introduce several aspects of the analysis and modeling of the treatment process characterizing the cooperation within multi-professional treatment teams. We will determine what is meant by a treatment process in order to then look at five views and four levels of their description. We will introduce possible methods for surveying and describing it. Currently an extensive analysis of the current state of the treatment process and of the weaknesses is underway in the Department of Child and Adolescent Psychiatry of the Heidelberg University Medical Center.
