Jana M. Celikler examines the creation, maintenance, and design of communication structures and processes within situation briefings in the staff work of civil and disaster protection organizations. Based on a conversation analysis of 45 situation briefings, which the author documented through participant observation, she develops a phase model that represents the individual phases in the communication process of a situation briefing, taking into account phase-specific communication patterns. Based on her findings, she formulates design recommendations for conducting situation briefings.
