Abstract: Building up a proper understanding of a large-scale incident is an important and difficult process. We envision a working environment for decision makers in crisis management situations that allows them to work with information in various ways. That will stimulate them to think critically in processing the information they receive-All in support of rapid sensemaking and decision making. To realize this ambition, we combine various technologies into an integrated support concept called the Critical Thinking Environment (CTE), aimed at tackling critical issues in sensemaking.
