Certain embodiments herein relate to modeling relationships between users, network elements, and events in an organization. Organizational information regarding users and network elements may be collected and analyzed to create a relationship graph relating users and network elements. The relationship graph may include nodes representing users and network elements and edges connecting pairs of users and/or network elements. The edges may be weighted based on a number of factors, such as operational dependencies, user preferences for receiving information associated with events, and a user's historical actions, which may determine whether a user may receive an event. A relationship graph as described herein may be leveraged to provide various uses, including generating a relationship subgraph that may allow users to identify the impact of events on other users and network elements in an organization.
