Charting the invisible: using network science to understand organizations and business communities

Behind roles and processes, organizations operate as networks of relationships. Using network-science tools, we analyzed posts and replies from a long-standing sales-network business community (October 2023 – July 2025) to understand how information circulates. The results reveal a highly active core, a more loosely connected periphery, and a small set of key users who sustain cohesion and keep the network connected even when some members leave.
