What two aspects are necessary for influencing a group?

Influencing a group effectively relies on two key aspects: achieving the group's goals while ensuring the group's dynamics are maintained positively. Group achievement refers to the collective objectives that the group works towards, such as completing a project or reaching a consensus on decisions. When a group focuses on achieving its goals, it fosters motivation and accountability among its members.

Group maintenance, on the other hand, involves nurturing the relationships and ensuring a supportive environment within the group. This includes building trust, encouraging communication, and managing conflicts. By balancing achievement with effective group maintenance, group members feel valued and engaged, which leads to a more cohesive and productive team dynamic.

While the other choices include important concepts related to teamwork, they do not encapsulate the crucial balance of objectives and interpersonal relationships that are necessary for truly influencing a group. Team spirit and competition, for instance, emphasize individual contributions and dynamics but may not inherently address the dual focus on reaching collective goals and maintaining group harmony.
