What action should be taken if the assignment is completed?

The correct answer highlights the importance of clear communication regarding task completion. Marking an assignment as complete confirms that all required actions have been finished, which is essential for keeping the workflow organized and allowing the next steps in the process to be executed. This action serves as an official record and keeps all team members updated on the progress of tasks, ensuring that everyone is aligned.

While notifying the supervisor is also critical in many situations, it is typically a separate step that occurs after marking an assignment as complete. Dispatching additional backup may not be necessary if the initial assignment is already finished. Similarly, requesting further instructions could indicate that the task was not fully understood or completed, which might not align with the statement of having finished the assignment. Thus, stating the assignment is complete succinctly signifies that all expectations have been met.
