This document summarizes Karl Weick's model of organizing for crisis management and public relations. Weick's model focuses on human interaction and interdependence within organizational hierarchies. It is based on sociocultural evolutionary theory, information theory, and systems theory. The model views the environment as sources of input information rather than physical structures. It involves three phases - enactment, selection, and retention - and emphasizes the cycles of input messages, standard procedures, and interlocked communication behaviors within organizations.
