The objectives of the call with regard to knowledge gathering, categorisation, analysis and evaluation for the goal of post-crisis lessons learning and use of this learning in practice define implicitly the need of a Community of Practice (CoP) for crisis response. Therefore, the ELITE consortium has a strong representation of experienced crisis managers and responders across all phases of crises and of knowledge management experts embedded within a CoP. The role of the ELITE knowledge management experts is to secure the best acquisition, categorisation, and analysis of tacit, fragmented knowledge acquired by crisis management responders, and to ensure best practice insights. The ELITE CoP is assembled around a web solution comprising a repository of best practices and guidelines as well as social media features (ELITE’s living document). During the project’s lifetime, ELITE uses a holistic method that addresses all relevant phases of major crises along with their systemic relationships. After ELITE’s project period, the living document is targeted as a Wikipedia-like solution with the necessary infrastructure and funding system so as to attract and serve the whole spectrum of end-users and crisis decision makers in Europe. Finally, to promote future research on this topic, ELITE will identify major remaining gaps and deliver recommendations for future research.
