Introduction: Proposes a systemic approach to Public Sector Information (PSI), defined as comprising entities in four categories--citizens, businesses, policymakers and administrations. This system also comprises four categories of information--on citizenship, economic and social development, policy and administration. Methods: A selective literature review was conducted to produce a convergence of perspectives from different fields, to provide the foundations for the stakeholder model. Analysis: The implications of the systemic approach to PSI, are: a) a holistic and open view of the entities and elements involved; b) clarification of the role of each of the stakeholder groups; c) commitment of each group to the public sector information system, and hence co-responsibility for the system. The principle of co-production is applied to the PSI system, by building on lessons from development studies. Results: A model is developed where the different groups of stakeholders are seen as groups of people and organizations with distinctive characteristics, playing different roles, but not mutually exclusive regarding their participation in the different subsystems. Conclusion: Success in adopting the proposed model may depend on preexisting characteristics and conditions of each socio-political context, including existing levels of social capital, as much as on the implementation of technology to improve public service delivery. However, it is possible to build synergistic relations relatively quickly, through an imaginative application of "soft technologies", such as institution-building and organizational change.
