This research report on DEI interventions is an adaptation of the first deliverable of Leiden University of Applied Sciences for a wider reading audience. It presents definitions of key concepts, discusses the motives behind DEI, and the different types of interventions organisations implement. DEI work also receives criticism by scholars and practitioners, mainly the risk of DEI policies being symbolic rather than leading to real change and their potential to obscure systemic issues of power and discrimination. Research also indicates the importance of intersectional work on DEI.
