In this book, «administration» is broadly interpreted as the management of organizations. The reason for this lies in the fact that administration is generally viewed in the context of public - or in an even narrower sense - state administration. However, administration is also to be found in numerous other forms - in large enterprises, to name one example. Nevertheless, neither perspective comprises the full conceptual extent of «administration» in a broader sense, and to offer proposals for solutions. Thereby, the situation in public and private organizations equally is given particular consideration. Thereby, the study of differences and common features of management in public and private administrations is of particular interest.
