Reinventing Government and modernizing public administration is an important issue in public policy. There is a variety of reform strategies for achieving sustainable development and efficiency of public authorities, but until now, the proposed reforms have not been very successful. It is not surprising that meanwhile, trust in New Public Management partially vanished. Instead of having faith in the «economization» of public management, the question of values arises. In this book, the necessary change towards a Public Value Management (as a counter-movement in Europe against the merely economical way of modernizing public administration) is explained and reflected.
