Purpose – More and more cities are challenged by the general ineffectiveness of the public spending programme management and by the economic crisis. This affects the quality of urban services and the quality of urban lives. Coherently with this trend an international discussion started on the governance model behind urban service production: a model shift from public-private partnership (3P model) towards public-private-people partnership (4P model) is observed which is not yet analysed in depth (Majamaa et al., 2008; Zhang and Kumaraswamy, 2012). New urban initiatives are growing in number, which consider people relevant actors of the service ideation and creation aiming at developing effective environment for urban service co-creation (Sibukele et al., 2012).
Within the perspective above, the main purpose of the paper is to highlight the role of co-creation in urban service provision (Jégou, 2011; Manzini et al. 2008; Manzini and Rizzo, 2011). The paper wants to demonstrate how the 4P model represents a possibility to foster and drive large-scale changes in which different stakeholders can play meaningful role (Concilio, 2010; Fischer, 2006; Kernaghan, 2009). In particular it analyses what is the role of knowledge creation in idea generation for innovating urban public services.
Design/methodology/approach – Considering the main scope of the paper, the authors carry out a case-based analysis and report the results of a long process in the urban environment of the Milan municipality experience in rethinking urban green areas growth and management. The co-creation process is described considering its bottom-up nature and its interaction with the local administration when moving from deliberation to decision making. In particular it is analysed in order to envision how some small (self-organized) criticalities/opportunities (Puerari et al., 2013) emerged in the city of Milan can be captured, coordinated and amplified to play a meaningful role in defining/envisioning possible futures that can enhance larger changes. Hence, some specific co-creation sessions are described (with the use of cognitive mapping tools) and analysed in terms of knowledge contents and dynamics relevant for the shift from deliberation to decision making and the kind of governance models arising from the co-creation process.
Originality/value – The originality of the paper stays, first, in focussing on the role played by co-creation in the creation of knowledge and in the generation of ideas for the innovation of urban public services. Second, the methodological aim of the paper is exploring the potentials arising when integrating co-design tools and methodology with knowledge mapping tools.
Practical implications – Cities are looking for new ways to create and produce urban services that can respond to citizens needs in a more effective way. Practical implication of the proposed paper are specifically related to the lessons learnt from the described experience and analysis of the Milano case within the framework of urban green areas development and management.
