Functional requirements are the same as day-to-day Crises are very different: Abrupt changes in scale, topology, traffic volume Crises are no different:

What Makes a Crisis? Changes the operating environment that are: Abrupt Unexpected Substantial Resulting shock loads on infrastructure Heightened attention Emotional arousal

Applications in Public Safety and Emergency Management Receiving requests for service Dispatching and tracking resources Storing, retrieving and sharing knowledge Perceiving events and conditions Planning and coordination Maintaining morale and community

Key Concerns Discovery Identity Attention Management Mesh by Design

Discovery Whos who, where and when? Roles, relationships and capabilities Location and presence Hierarchy is just the beginning…

Identity Persistent constellations of attributes Human, but also collective and automatic Authority to cast an identity into being Domains of identity, webs of trust The half-life of identity

Attention Management Push and pull Multicasting Relevance and salience The normalcy bias and the affective filters Imputed motive: People buy sources We get what we measure

Mesh by Design Counteract the technical and organizational tendencies toward hierarchical topologies, SpoFs Mitigate the WAN / LAN distinction (fractal topology)
