Which of the following is NOT a facilitator of horizontal communication?

Horizontal communication refers to the exchange of information and ideas between individuals or groups at the same level within an organization or community. It is essential for collaboration, information sharing, and decision-making without the constraints of hierarchical communication.

In this context, project teams, committees, and team building activities all directly promote horizontal communication by enabling collaboration among members who share similar roles or statuses. These groups encourage sharing perspectives, skills, and resources, which enhances teamwork and collective problem-solving.

On the other hand, community residents, while they may engage in horizontal communication, are not typically seen as facilitators within a structured organizational context. Community members may communicate horizontally among themselves, but the term "facilitator" more accurately describes organized groups such as project teams or committees that are formed specifically to promote communication and cooperation. Thus, the option regarding community residents does not function as a deliberate facilitator of horizontal communication in the same way as the other choices do.
