Kommunikationsmanagement im öffentlichen Sektor

For successful communication management, the "individualisation" and "differentiation" of specific framework conditions of individual types of institutions are more than essential.
For the (de-)centralised federal administration in Germany, starting from the core administration (e.g. ministries, offices, etc.) or public corporations, up to mixed-economy institutions, the following credo applies:
"The more decentralised the institution, the more autonomous the management."
This raises the question of whether there are different or specific problem areas in communication management for each type of institution and how these are related to the degree of autonomy?
