The formative characteristic of today’s and tomorrow’s world is complexity. Its attributes are met in all areas of social, economical and ecological life. They determine the increasing demand for understanding relationships, connectivity and dynamics. This is especially true for large systems in the ecological and technological sector, micro- and biotechnology, and as well for economics, politics, society and information technology.

Apparently theoretical analysis by itself is not sufficient to determine the consequences of complexity. It has to be complemented by the direct handling of systems as such. The full extent one is challenged by successful complexity management is revealed by combining theory and own experience.
