Contrary to traditional diagnostics, which determine the person's deficits, systemic diagnostics, as we carry out, emphasize the personal abilities and resources, consider structures, connections, and relationship patterns in order to comprehend the development of learning processes and to intervene in a supportive manner.
Systemic diagnostics is intervention-focused, meaning diagnostics and intervention are two aspects, which are not separable in day-to-day life and correlate with one another.  Each diagnostic process incorporates an intervention process and, vice versa, during each intervention process the person is observed.  Most information is obtained through observation, which necessitates two abilities, first the ability to discern differences and secondly the ability to give meaning to the observed differences.
