The demands on administration have steadily increased over the past few decades. As a result, education is becoming more challenging and broader. This textbook attempts, for the first time, a comprehensive interdisciplinary approach to administrative science. It encompasses all areas of administrative science in one volume: fundamentals, history of administration, administrative policy, administrative law, administrative economics, administrative sociology, administrative psychology, administrative communication and culture, as well as administrative evaluation and reform. Thus, this introduction serves as a companion throughout the entire course of study and provides a clear orientation in the diversity of education.
