The main objective of this deliverable is to propose a preliminary collaborative governancemodel, based on partnership between private actors (citizens and companies) and publicadministration. Co-production through government platforms is a promising avenue for the redevelopment of public services. However, to make this work, it requires a clear system ofground rules, a model, on how public services can be delivered in partnership, for instance,individual and collective responsibilities, rules of interaction and management of access. Task 2.1 is focused on how collective action takes place in the context of digital public serviceprovision. To study this, we systematised the state-of-the-art on traditional and digital coproduction processes in order to identify key variables and conditions that must be met for coproduction to be effective. Even though we planned to conduct research into the successful andunsuccessful cases of co-production in the context of digitally co-produced services, we werehindered by the corona pandemic. However, the comparative analysis will be conducted in 2022and will eventually be incorporated in task T2.2 and D2.2. D2.1. describes the first outcomes of our performed research activities in order to define theadvanced governance model. The output of this deliverable is useful for other deliverables andother Work Packages (WP). For example, the co-business model (D2.4) addresses challengesidentified in this deliverable and the governance model is related to the identification ofINTERLINKERS in WP3. This report presents a preliminary model, developed during the first year of the project. First,we will define the meaning of co-production and public services. We will then conceptualisethe key elements of the co-production process: the different steps, issues to be addressed andstakeholders to involve. Finally, we will identify the steps forward in the next phase, to worktowards an advanced governance model.
