This article explains how systems theory can be used for a profound understanding of the phenomenon of interpreting. An online tool based on systems theory for the analysis and simulation of complex situations and processes was used in class for training students on how to do research in Interpreting Studies. It was found that such an approach helps to better understand and reflect the complexity of interpreting and to familiarise the students with research on interpreting. Moreover, this approach seems to be promising for interpreting research as a whole. Such a tool could be beneficial for structuring, fostering and performing interpreting research if an online model of interpreting is created jointly by the interpreting research community.
