What is one identifying factor of an ineffective crew?

An ineffective crew is often characterized by a lack of clarity regarding individual responsibilities among its members. When crewmembers are uncertain about their roles throughout the flight, it can lead to confusion and mistakes, which can compromise safety and mission effectiveness. This disconnect can hamper decision-making processes and hinder effective coordination necessary for successful operations. In contrast, effective crews exhibit clear communication and understanding of their specific duties, which enhances teamwork and operational efficiency. The other provided choices represent positive aspects of crew dynamics, highlighting effective communication, shared information, and situational leadership, all of which contribute to a well-functioning team rather than indicating ineffectiveness.
