Which term refers to the mutual understanding and expectations among group members?

The term that refers to the mutual understanding and expectations among group members is "Common values." This concept encompasses the shared beliefs, principles, and standards that guide the behavior and interactions of team members. When a group has common values, it fosters a cohesive environment where individuals feel aligned in their goals and operations. This alignment helps to establish trust, respect, and cooperation among team members, enabling them to work more effectively towards their shared objectives.

While other terms like "Common interests" may highlight shared goals, they do not inherently capture the deeper understanding of expectations and beliefs that influence a group's dynamics. "Collective Identity" refers to how group members perceive themselves as part of a whole, which is influenced by values but does not solely define the mutual understanding between members. "Team Dynamics" involves the interactions and relationships within a team, but again, it does not specifically denote the foundation of shared values that lead to those dynamics. Thus, the focus on common values as the core of mutual understanding is why it stands out as the correct answer.
