Successful crisis management depends on collaboration between different stakeholders and involved organizations, it also relies on making a good decision in a short time. Therefore, it requires that actors communicate and share information on the field to achieve awareness about the event. Due to an ineffective communication in emergency response, awareness and collaboration are impacted, for that we aim to study the activity and the communication in inter-organizational crisis management and extract the various problems that actors encounter in information sharing which prevent them from achieving their goals. We present in this paper our initial result in which we model the dependencies between different actions, information and actors.
