The term 'situation center' often evokes thoughts of war, floods, refugees, storm damage, wildfires, terrorist attacks, or bank robberies with hostages. However, there are also events organized by public municipalities such as city festivals, community celebrations, groundbreaking ceremonies, topping-out ceremonies, opening events, or memorial services that can quickly turn into a crisis situation. The event management then requires professional support from a situation center that oversees the event. The main task of a situation center is to provide the event management with current information. This is where situation briefings and crisis meetings of the security and crisis team take place. Additionally, it serves as a base for other event participants. This book supports the management of a situation center with advice, tips, and checklists.
