Demonstrating impact is central to ensuring the long-term sustainability of a research infrastructure. Building on existing impact assessment frameworks (e.g. developed by the Organisation for Economic Cooperation and Development OECD, or by the European Strategic Forum on Research Infrastructures ESFRI) focused on research infrastructures, we will collaborate to adapt and refine these approaches based on the needs and specificities of the Italian, Norwegian and Portuguese Nodes of ELIXIR. This effort will be done with continuous sharing among team members and in close collaboration with the ELIXIR Impact Assessment Officer. In addition, opportunities to collect contributions from other Nodes will be taken advantage of, namely via direct requests for feedback, short surveys and/or semi-structured interviews. Synergies with relevant ELIXIR activities will be sought, e.g. the impact work taking place under the Training Platform, the ongoing RI-PATHS project (“Research Infrastructures Pathways of Impact” ), and the ELIXIR-CONVERGE project.
