interruption requires activation of the disaster plan
Communication methods to be used
Training required, immediate and ongoing, in terms of skills needed to
perform disaster recovery
Which information services will need to be restored, in what order and to
what level of functionality
What resources need to be, and have been, set aside in terms of
