Overall, it can be stated that “A more precise definition of interdisciplinary research is needed so that funding agencies and researchers themselves can identify the competencies and resources necessary for successful interdisciplinary contributions to science“ \citep{Aboelela_2007}. Hence, the goal of the paper is to provide a more fine-grained understanding on interdisciplinarity and its research impact. The research question is as follows: How does the research impact vary depending on the kind, degree and time-frame of IDR?
3. Methodology
- Systematic review as used in medicine: a systematic literature search, followed by a comprehensive summary and categorisation of the retrieved documents is used to relate and to assess the current state of the art of the Impact of IDR \citep*{Green}.
