When delegating, the crew leader should make sure the crew member understands what to do...

Effective delegation involves clearly communicating the task and ensuring the crew member understands not only what to do but also their level of responsibility (A) for completing the task. While understanding risks (B) and following safety regulations (C) are important, and accountability is necessary, the immediate need in delegation is to define the scope of their responsibility. Focusing on blame (D) is counterproductive to effective teamwork. (Fundamentals of Crew Leadership, Fourth Edition, NCCER, Section 5.3.2 Principles of Effective Delegation)
