Regular training is crucial in order to be able to react confidently in crisis situations, emergencies and unexpected events. As part of integrated incident, emergency and crisis management, concepts and processes must not only exist on paper, but must be actively practiced and trained. This applies to both the emergency services and everyone else involved - from the staff in the command center to the crisis team. Only by running through realistic scenarios can it become clear how well institutions and individuals are familiar with the technology, whether potential weaknesses are being identified and whether everyone involved is actually equipped for an emergency.
