In the circular economy, however, these frameworks no longer appear to be sufficient, due to the difficulty in identifying multiple design strategies for the different product life cycles across time dimensions. By adopting a Design for X (DfX) approach, this paper develops a multi-hierarchical DfX framework that allows designers to incorporate different strategies to better address product life cycles. This framework could facilitate the further development of a more comprehensive and interdisciplinary DfX tool. A key part of the method deployed is an interview guide approach, where five experts from across academia and industry, were interviewed. This qualitative research draws on their diverse expertise and generates an intersectoral link between different fields. Moreover, the DfX tool can be used to highlight relationships between different circular economy strategies, by providing insights into how interdisciplinary design decisions influence each other. Such an approach could allow designers to effectively visualize a bigger picture and positively influence the application and acceleration of the circular economy.en500 Naturwissenschaften und Mathematik600 Technik, Technologie300 Sozialwissenschaftendesign for Xcollaborative designinterdisciplinary approachcircular frameworkdesign toolConference Object
