The transition towards a circular economy requires an overarching perspective that recognises the dynamic and interdisciplinary nature of our current economic growth landscape. Circular economy inherently involves numerous stakeholders across the product life cycle. To establish efficient circular economy practices among these actors, this study suggests a novel framework for developing collaborative and interdisciplinary decision-making tools. By looking into relevant literature, organising a workshop, and analysing standard tools used in a circular economy like KPIs, risk analysis, Cost-Benefit Analysis, etc., we managed to capture the multidisciplinary challenges and dynamics faced by stakeholders of the circular business model. The contribution of this paper is the development of a framework that bridges requirement management techniques from product development practices with circular economy principles to facilitate effective decision-making processes. The framework effectively balances diverse stakeholder requirements, addressing uncertainties and multi-ownership challenges through product life cycles. This framework may be used to validate existing tools used by businesses and systematically develop new ones when needed. By facilitating collaboration around the circular economy, this framework not only reduces the environmental impact of economic growth but also encourages society to move towards more collective efforts to achieve sustainability. Finally, this article highlights the importance of a transdisciplinary approach in a systematic and effective transition to a circular economy.
