The process of granting authority to carry out specific functions is called the delegation of authority. Delegation of authority:

• Grants authority to carry out specific functions
• Is issued by the chief elected official, chief executive officer, or agency administrator in writing or verbally
• Allows the Incident Commander to assume command
• Does NOT relieve the granting authority of the ultimate responsibility for the incident

Ideally, this authority will be granted in writing. Whether it is granted in writing or verbally, the authorities granted remain with the Incident Commander until such time as the incident is terminated, or a relief shift Incident Commander is appointed, or the Incident Commander is relieved of their duties for just cause.
