The Federal Emergency Management Agency teaches us that Emergency Preparedness consists of two types of activities following a disaster: Response and Recovery.  These activities are performed by different groups of people and involve different resources.  Response starts with 911 relying on rapid communication.  It unrolls over the next several hours, working into Recovery.  In Business Continuity Planning or BCP, we separate Recovery activities into Infrastructure Recovery (power, computing, communication, facilities) and Departmental Recovery, or Business Unit Recovery.
