These crises propagate across the EU's complex systems and tightly integrated infrastructures and pose immense challenges to Member State authorities, which are forced to collaborate across regional and national borders, and across policy and system boundaries. Planning and preparedness for these large-scale disasters and complex crises are thus essential. This requires an intelligent, multi-faceted, systematic and coordinated approach, which is to be supported by state of the art technologies through the identification of all the core tasks and factors (decision making, coordination, communication, etc.), that facilitate a crisis response. IN-PREP aims to develop an integrated programme, capitalising on integrating novel technology tools to support transboundary preparedness activities and to interlink a wide range of stakeholders for a truly transboundary and collaborative response. IN-PREP helps to improve transboundary response planning, offering a novel and holistic approach that makes extensive use of situation awareness, decision support, scenario-building, vulnerability assessment and inter-coordination capabilities. This report presents a description of the IN-PREP End User Workshop #1 held in Leiden, the Netherlands, on the 23rd and 24th of November 2017, and of the End User Workshop #2 held in Berlin, Germany, on the 21st and 22nd of February 2018. These workshops were dedicated to identifying the End User Requirements (EURs), which will be reflected in D2.6, entitled ""User Requirements"". The latter will remain a living document as it will be updated throughout the project and will form the base for the definition of IN-PREP technical specifications. The first workshop focused mainly on early identification of End User Requirements. The main outcome was the identification of the six steps to be taken in training and response planning through the integrated platform. All the feedback obtained from the first workshop was discussed and validated in Workshop #2 towards the refinement of the end user requirements and the consolidation of the final version. Additionally, the second workshop was used for ethics and privacy impact assessment discussion, and for developing a set of risk criteria against which to assess, analyse, map and therefore minimise and avoid project risks.en620report
