In inter- and transdisciplinary contexts, heterogeneous expertise, experiences and thought styles meet, and different people collaborate. Transdisciplinary processes are therefore considered to be particularly challenging. While disciplines or well-defined artistic genres have developed specific methods that promote processes of finding topics, doing research, collaboration or production, transdisciplinary projects are often characterised by the fact that they organize their activities in a context-specific manner or spawn hybrid instruments. As different as transdisciplinary projects are, so, too, the paths, the methods they use and the procedures they develop are diverse. Generally, valid statements on procedures and methods are therefore difficult to formulate and practice – unless transdisciplinarity should again become a discipline. At the same time, the need remains to have guidelines and tools at hand to facilitate the implementation of transdisciplinary projects.
