Performancemeasurement systems in public service networks. Thewhat, who, and how of control

This study explores the concept of a network Performance Measurement System (PMS) and how it helps in terms of what is being controlled in the network, which exerts control and how this control is achieved. In analyzing PMSs, the distinction was made between their hierarchical and their socializing components. An exploratory case study was carried out on a public service network in charge of a local public transport. Findings from the case study are used to reach a preliminary conceptualization whereby network PMSs are systems consisting of three main building blocks activated on demand by three main network actors and where there is coexistence and blending between hierarchical and socializing practices.
