Is controlling the key to solving the pressing issues in public administration? Public business administration provides the necessary management tools required to efficiently shape administrative practices. Increasingly complex issues demand enhanced support for leadership. Controlling is an important instrument not only in the private sector but also in public administration. Based on the existing differences between public administration and the private sector, operational and strategic management tools suitable for controlling are presented, addressing controlling from both an institutional and functional perspective. Further chapters of the book deal with controlling tools appropriate for use in public administration, the reporting that is necessarily associated with controlling, as well as recent developments and participation controlling. Numerous practical examples from administration provide insights for the respective public sector. The target audiences of this didactically well-prepared foundational work are on one hand students at universities for public administration, vocational academies, and administrative and business academies; on the other hand, practitioners in public administration and public enterprises who deal with controlling.
