In order to effect the preparedness plan, a survey of the target area must be executed as to people, resources, buildings and all other aspects affecting logistics.
The results of the survey must be analyzed as to strategic actions to be taken in event of disaster. For example, how many elderly people who are alone need to be evacuated should the need arise/ How many multi-storied buildings are in the target area?
A viable and efficient plan must be developed based on the analysis and based on government preparedness requirements as to key groups and key personnel etc (who to move first; to whom to give vaccines first etc).
The plan must then be communicated to all effected branches from first responders to later responders and mitigated by logistic requirements and limitations.
