    Efforts towards a circular economy are accelerating and gaining more attention. Since product's lifecycle is mostly determined during early product development phases, it is crucial to support those phases with explicit strategic directions. This paper examines the possibility to aggregate various definitions of end-of-life (EoL) strategies in a visually compelling way. We propose a taxonomy for communication between multidisciplinary product development teams using ReX, an abbreviation for alternative EoL strategies starting with prefix 'Re', such as reduce, reuse, repurpose, repair, remanufacture, recycle, and recover. We construct our taxonomy based on a) EU Waste Directive, b) a systematic literature review, and c) relevant theoretical constructs. Then we discuss whether ReX allows assessing potential EoL alternatives, and steering the product development efforts. Finally, we suggest ReX for supporting decision-making when several stakeholders are involved, common language is sought for, and significant EoL related decisions are made at the early phases.
