The aim of our study is to present the administrative system in some European Union member states. The systemic approach offers us the possibility to achieve a comprehensive overview of the scope and content of public administration. In terms of systemic evaluation, public administration is seen as a social entity specific to certain period of development, characterized by a mode of action, structure and logic. Starting from the systemic approach we will highlight how member states' constitutional regulations tailored the European administrative systems. Public administration, as a system, is understood as an evolutionary process, with objects, attributes and relationships that combine and allow proper operation. Also, public administration system approach provides the basis for a consistent and rigorous approach to an ideal model of government that summarizes all the advantages - goals for any administration, namely: nationality, effectiveness, optimum citizens serving etc.
