Which group evaluated the impact of leadership behavior on the performance of small groups?

The group that evaluated the impact of leadership behavior on the performance of small groups is the University of Michigan Studies. This research primarily focused on identifying the relational behaviors and task-oriented behaviors of leaders and how these behaviors influenced group performance and satisfaction. The studies provided valuable insights into how different leadership styles could lead to better outcomes in small group settings, emphasizing the importance of interpersonal relationships and team dynamics.

While the Ohio State Studies also investigated leadership behavior, they are more focused on the dimensions of initiating structure and consideration, which are components of leadership rather than the broader impact on small group performance. The Blake and Mouton Model concentrated on leadership styles represented in a grid format, emphasizing the balance between concern for people and concern for production, but it did not specifically evaluate the performance of small groups. The Harvard Business Review is a publication that disseminates a wide array of research articles on various business topics, including leadership, but it is not an entity that conducted original research evaluating such behaviors in small groups. Therefore, the University of Michigan Studies is the most appropriate choice for assessing the impact of leadership behavior on small group performance.
