With Connections, the University of Zurich provides a collaboration platform for all employees, students and units of the university, be it faculties, departments or competence centres. With minimal guidelines, the university leaves it to the users to get the most out of their daily collaboration. IT services supports the platform by offering courses and thus prepares interested members and future community managers for an optimal application. Current case studies illustrate how different the approach can be in a decentralized organization like a university. The challenges the decentralized units have to overcome and why the platform also helps to question internal processes are illustrated.
