Understanding Social Networks

Analyzing Network Ties and Key Network Roles

Once the data is collected, SNA software is used to create the maps for analysis. The maps draw incoming and outgoing arrows between people to show the number of ties coming into a person (contacts that the person receives) and the number of ties outgoing (contacts that the person initiates). There are three key roles in a network. Central connectors are people linked to the greatest number of people. Boundary spanners are people who connect one network to another within the company or even across organizations. Peripheral specialists have special expertise that can be drawn upon even though they often work independently of the group.
