What is described as the ability of a group to unite and work together?

The ability of a group to unite and work together is best described by the term "cohesiveness." This concept refers to the degree to which group members are attracted to one another and motivated to stay in the group. Cohesiveness facilitates effective collaboration, enhances communication, and fosters a sense of belonging among members, thus improving overall group performance. When a group exhibits cohesiveness, individuals are more likely to support each other in achieving common goals, share responsibilities, and engage in problem-solving as a unified entity.

In contrast, disunity indicates a lack of unity among group members, fragmentation refers to the breaking apart of a group into separate segments, and isolation signifies a situation where individuals or groups are separated from one another. These terms describe scenarios that are contrary to the collaborative spirit embodied in cohesiveness.
