Which of the following is a maintenance role that helps improve group effectiveness?

Gatekeeping to prevent domination is a crucial maintenance role within a group that contributes to improving group effectiveness. This role involves ensuring that every member of the group has an opportunity to contribute to discussions and decision-making processes. When one individual dominates the conversation or decision-making, it can stifle creativity, lead to groupthink, and diminish the overall effectiveness of the team. By acting as a gatekeeper, this role helps facilitate balanced participation, fostering a more inclusive environment where diverse perspectives can be shared and considered. This, in turn, enhances collaboration and leads to better outcomes for the group as a whole.

Other options may serve important functions within a group, but they do not specifically focus on maintaining group dynamics and inclusiveness in the same way. Summarizing information is a valuable task that helps clarify and consolidate discussions but does not actively manage group participation. Creating cross-departmental committees could be an organizational strategy to enhance collaboration but is more a structural initiative than a maintenance role within an existing group. Similarly, giving presentations on organizational goals serves to inform and align a group but does not directly address the dynamics of participation and interaction among group members. The unique focus of gatekeeping on preventing domination is what makes it a key maintenance role for improving group effectiveness.
