Which of the following is considered a major influence on a group's success?

Espirit de Corps refers to the spirit of camaraderie, unity, and shared purpose within a group. This sense of belonging and collective identity can significantly enhance morale and motivation among team members, leading to improved collaboration and effectiveness in achieving group goals. When individuals feel a strong connection to their peers and the mission, they are more likely to work harmoniously and contribute positively to the team's overall success.

While leadership style, available resources, and group size are all important factors in a group's dynamics, they influence success in different ways. Leadership style can shape the group's direction and how effectively tasks are managed. Resources provide the necessary tools and support for completing objectives. Group size can impact communication and cohesion. However, without a strong esprit de corps, even the best leadership, resources, or optimally sized group may struggle to achieve success, as the collective commitment and motivation are crucial for high performance and achieving shared objectives.
