This contribution aims at providing a systemic analysis of the approaches that have characterized the evolution of public management. The different ap-proaches are reported chronologically, after briefly mentioning some relevant points of Machiavelli’s thinking. Each of these approaches, whose most repre-sentative conceptual aspects are highlighted, is influenced by the institutional framework that defines priorities and purposes. The evolution of context, from the constitutional to the so-called relational state, has changed the focus of pub-lic action over time. Initially, the respect of procedures and rules was essential. Then, the aim of public management has gradually evolved towards a search for efficiency. In recent years, the requests coming from the various intermediate social actors have become remarkable. The main perspective is now the con-struction of relationships, collaborative interactions and partnerships between public and private subjects. Through the metaphor of systemic analysis, this work highlights the element of the public or-ganization (structure, operating mechanisms and processes) which is predomi-nant in each approach. In conclusion, the work focuses on the evolution of the role of citizens on public administration - from mere customers to coproducers - and tries to represent the great role of public organizations in generating value
