Abstract: This paper is about European networked crisis and disaster management and how to achieve more intelligent decision support and better collaboration. Although collaboration processes are established, the underlying information management tools today don?t support integrated electronic information management in multi-organizational scenarios. This leads to a fragmentation of relevant information into pieces held by different stakeholders. Recently, the concept of the Common Information Space has been introduced as possible solution. This paper looks to the domain of Air Traffic Management where a similar problem was tackled by a concept called System Wide Information Management. The paper starts with describing the operational context, the unresolved needs, and the derived requirements. Experiences from the Air Traffic Management domain are gathered and compared with current solution concepts from the public safety domain. The paper concludes with lessons learned during the on-going development in the public safety domain.
