Which of the following is NOT a style included in the Hershey/Blanchard model?

The Hershey/Blanchard model, also known as the Situational Leadership Theory, includes specific leadership styles that are designed to help leaders adapt their approach based on the development level of their team members. The styles identified in this model are directing, coaching, supporting (also sometimes referred to as participating), and delegating.

The collaborating style, while it may seem similar to some of the functions of the supporting style, is not part of this particular framework. Instead, the model emphasizes the balance between task behavior and relationship behavior, allowing leaders to shift their style according to the follower's maturity and readiness for a task.

Recognizing the characteristics of each of the actual styles within the Hershey/Blanchard model helps to further understand how effective leadership is situational and must adapt to the followers’ needs. The inclusion of the participating, coaching, and delegating styles highlights the model's focus on varying levels of guidance and support in relation to follower readiness, further emphasizing why the collaborating style does not fit within this framework.
