Interaction Parts of the Disaster Management Process Situation Leadership Decision Making Coordination
Disaster and disaster area
Instantaneous,unpredictable,sensitive to initial conditions; high level of noise.
Citizens self-organize and evacuate based on risk perception dynamics and information available.
Self-organizing and local with varying extended effects.
Disruption of energy, water transportation,Communication and other system binders.
Macro: Local, Central command and infrastructure regulatory structures
Intermittent information about selected unprioritized events; high level of noise.
Command and control strategies, self-organize, tasks delegated.
Intermittent, local and diffused across disaster area
Voice and data streams; mental models of situation developing and changing.
Meso: Working Group in Macro setting or locally
Intermittent information about selected unprioritized events; high level of noise.
Self-organized and delegated.
Within emergency response unit.
Face to face and voice; mental models for specific tasks developing and changing.
Micro: Individual biological and cognitive processes
Unpredictable events produce stress and prolonged work shifts, presentism, PS.
Entrainment to unit leader(s).
Time pressure produces stress; cognitive focus on short-term time intervals.
Entrainment to co-workers.
