Just as tactics define tactical resource requirements, resource requirements drive organizational structure. The size and structure of the Incident Command organization will be determined largely based on the resources that the Incident Command will manage.
As the number of resources managed increases, more supervisory personnel may be needed to maintain adequate span of control, and more support personnel may be added to ensure adequate planning and logistics.
It is important that the incident organization's ability to supervise and support additional resources is in place prior to requesting them.
Personnel and logistical support factors (e.g., equipping, transporting, feeding, providing medical care, etc.) must be considered in determining tactical operations. Lack of logistical support can mean the difference between success and failure.
