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.
