During which phase does a group reach the level of maturity where members make their own decisions?

The correct answer is C, which refers to the D4 phase in the context of team development and the situational leadership model. In the D4 phase, team members exhibit high levels of maturity and competence. They are capable of working independently and making decisions collaboratively without the need for close supervision. This phase reflects a developed level of trust, cohesion, and shared understanding among team members, allowing them to take ownership of their roles and responsibilities within the group.

In this stage, leadership can shift toward a more delegative approach, where leaders provide support and resources but allow the team to operate autonomously. This not only fosters a sense of empowerment among team members but also encourages them to be more innovative and proactive in driving team goals forward. The emphasis on collaboration and decision-making independence is key to reaching the maturity expected in D4, making it a pivotal phase in the development of a high-performing team.
