Demands on public sector to become more open and embrace new possibilities given by ICT are constantly rising. EU as well as OECD are putting high pressure on governments to improve service level for citizens and at the same time lower cost and facilitate democratic processes. The authors have gathered statements from the development of an open social e-service at a Swedish municipality and projected these onto directives regarding open government from authorities. Using goal modelling techniques a goal model for open social e-services has then been created. The model consists of four aspects that have to be taken into consideration when building open social e-services: democracy, professionalism, citizen service and administration. The model has been evaluated by research and practitioners and can facilitate the further development of open e-government in Sweden and possibly in other countries. Examples are requirement specifications for open e-services and guidance for business process modelling for the social service sector.
