"Outcome-Based Performance Management in the Public Sector" offers a comprehensive analysis of the application of an outcome-oriented approach to performance evaluation in the public sector. The book examines how governments can assess the impacts of their policy measures both in the short term and the long term. It highlights the necessity of looking beyond the perspective of individual institutions and considering the interactions between various organizations. Given the increasing complexity of social challenges referred to as "wicked problems," the book provides theoretical and empirical insights into the development of performance management systems that are focused on outcomes. These systems are crucial for managing the dynamics and the multitude of actors and sectors involved in solving such problems. The approaches presented in this book promote the creation of more flexible and comprehensive governance structures that are essential for effectively addressing complex societal challenges.
