### Explanation Most organizations and online communities have hierarchical structures that define roles, responsibilities, and relationships between members. Understanding these structures can reveal pathways to identify key individuals and their connections: The **Leadership Hierarchy** within organizations and online communities includes administrators and moderators with elevated privileges, team leaders and project managers, and department heads and executives. These individuals hold significant authority and influence over the group's operations and decision-making processes. An **Activity-Based Structure** highlights the most active contributors and participants, regular content creators and discussion leaders, and distinguishes between core community members and casual participants. This structure helps in identifying those who are most engaged and influential within the community. **Responsibility Patterns** reveal task owners and assignees, decision makers and approvers, and subject matter experts. These patterns provide insights into who is responsible for specific tasks, who has the authority to make decisions, and who possesses specialized knowledge. By analyzing these hierarchical relationships, investigators can map organizational structures, identify key personnel and their roles, trace connections between members, and understand information flow and decision-making paths. ### Examples {{some links to articles, videos, etc}} ### Types - behavioural - business ### See also - [[SOWEL-2.
