What describes the interaction or communication between people and groups?

The interaction or communication between people and groups is best described by the concept of "engagement." Engagement refers to the proactive involvement and participation of individuals in discussions, activities, or projects, fostering meaningful connections and collaboration. It emphasizes the importance of building relationships and understanding among participants, which is vital for successful teamwork and effective communication.

While platforms may serve as tools for communication, and networks can represent the structured connections among individuals or organizations, those terms do not capture the essence of active interaction and mutual participation that engagement embodies. Collaboration, while related, specifically focuses on working together toward a common goal, rather than the broader concept of interaction that engagement covers. Thus, "engagement" is the most accurate term for describing the dynamic interaction and communication that occurs between people and groups.
