Transferring knowledge is a real challenge especially when there are many independent organisations involved in developing an information system. This research tries to find out how the core challenge is met in this context. The research material is collected in a case where several universities were involved in implementing an information system to support student mobility between them. We concentrate on building interface between two information systems when distinct parties were on charge. The special nature of academia is emphasised in the research because there is no organisational command lines between different departments in universities. This character adds the need for interaction and communication in the project.
