Final answer:
In NIMS, assignments are given under the 'Management by Objectives' characteristic, which ensures that tasks are aligned with overarching objectives and strategies.
Step-by-step explanation:
Under the National Incident Management System (NIMS), you are issued an assignment to accomplish a task under the characteristic of Management by Objectives.
This involves establishing overarching objectives, developing strategies based on those objectives, assigning tasks designed to achieve the identified strategies, and providing clear direction to resources assigned to perform the tasks.
This systematic approach ensures that there is a clear chain of command and that every individual or team has specific, actionable tasks that support the overall strategy and objectives of the incident management efforts.
