Final answer:
Branches within the ICS organization can be established geographically or functionally, aligning with bureaucratic principles of hierarchy of authority and impersonality to promote clear command structures and professionalism in large, impersonal organizations.
Step-by-step explanation:
Branches within the ICS (Incident Command System) organization can be established geographically or functionally. This organizational flexibility is essential for structuring the ICS to meet the needs of various incidents. For example, establishment of branches can be based upon functions, such as giving certain responsibilities to a branch dedicated solely to logistics or planning. Likewise, geographical branching allows different areas of an incident to be managed separately but cohesively within the ICS structure. This aligns with the principles of hierarchy of authority and impersonality, key components in a bureaucracy, ensuring a clear chain of command and the removal of personal feelings to promote professionalism. The instrumental function of each branch or group is to be oriented toward task completion and goal achievement, coinciding with the formal organizations typically being large and impersonal.
