INDIGO aims to provide a revolutionary solution that will enable inter-organisational preparation and support response to transboundary crises and disasters, in any environment. INDIGO will allow for inter-organizational exercising, information sharing and analysis – mining both horizontal and vertical relations. With regard to the latter, the relation between central command centres and field units is traditionally underdeveloped, both before and during crises. First responders are insufficiently involved in large-scale strategic exercises because these are very complex and expensive to organise and manage.
