Which role includes implementing new policies and acting as a model for subordinates?

The role that involves implementing new policies and acting as a model for subordinates is best described as the leader role. Leaders not only guide and motivate employees but also set the standard for behaviors and practices within the organization. They are responsible for fostering a positive organizational culture and ensuring that their team members understand and adhere to new policies and procedures. By modeling the desired behaviors and values, leaders influence their subordinates and promote alignment with organizational goals.

In contrast, the roles of figurehead, informational, and liaison serve different purposes. The figurehead role typically involves symbolic and ceremonial duties that do not directly relate to implementing policies or modeling behavior for others. The informational role focuses on gathering, disseminating, and processing information, while the liaison role emphasizes building relationships and networks outside of one's immediate work group. Thus, these roles do not encapsulate the essence of leadership in terms of implementing policy and providing a model to follow.
