Our goal was to assess current modus operandi and to identify design implications. We have carried out two expert interviews, two field observations and four group discussions with experts based on a fully functional prototype as IT artifact to concretize discussions. Key insights are that in this case localization of relevant resources is the most important aspect of situation awareness, and that state of current knowledge needs to be clearly shared within the command center.endecision makingsecurity forces at open air music festivalssituation awarenessinformation sharingshared information spaceText/Journal Article10.1515/itit-2018-00052196-7032
