In this episode, Marta and Willem discuss interdisciplinary work in public procurement and law in general. They reflect on their many personal experiences of working across disciplines and examine the recent push for interdisciplinary work in academia. They evaluate the positives, the negatives, and the relevance of both simple mono-disciplinary work in public procurement law, and inter-disciplinary collaborations and projects, focusing on the most common challenges and how to overcome them. In their discussion, they emphasize the importance of openness and mutual understanding in interdisciplinary collaborations. They discuss the optimal time for crossing disciplines during one’s studies and finally, for dessert, they talk about their approaches to teaching the interdisciplinary aspects of public procurement to their students.
