What is the correct hierarchical order from broadest to most detailed?

• A. Occupation, Job, Duty, Task, Sub-Task
• B. Job, Occupation, Duty, Task, Sub-Task
• C. Occupation, Duty, Job, Task, Sub-Task
• D. Occupation, Job, Task, Sub-Task, Duty

Answer: (A)

Understanding how responsibilities are structured from broad to specific helps you see how roles are organized. An occupation represents the broad field of work. Within that field, a specific job defines the particular role and its responsibilities. Each job is built around duties—the major functions a person in that job must perform. Tasks are the concrete actions that accomplish each duty, and sub-tasks break those tasks into smaller, more detailed steps. So the natural order from broadest to most detailed is Occupation → Job → Duty → Task → Sub-Task. This aligns with how roles are planned and assessed in training, ensuring each level clearly supports the next.
