Two nodes are connected if they regularly talk to each other, or interact in some way. Andre regularly interacts with Carol, but not with Ike. Therefore Andre and Carol are connected, but there is no link drawn between Andre and Ike. This network effectively shows the distinction between the three most popular individual centrality measures: Degree Centrality, Betweenness Centrality, and Closeness Centrality. Diane has the most direct connections in the network. She is a 'connector' or 'hub‘. However connections are only to others in her immediate cluster. Heather has one of the best locations in the network -- she is between two important constituencies. She plays a 'broker' role. The good news is that she plays a powerful role in the network, the bad news is that she is a single point of failure. Fernando and Garth have fewer connections yet the pattern of their direct and indirect ties allow them to access all the nodes in the network more quickly.

Projects can be more successful if you take the time to analyse the people and the relationships, connections between them
you’re not alone on your project – you’re probably only 4-6 degrees of separation away from someone who knows the answer
use social media, like blogs, linkedin, even twitter, are tools that can help you reach out to others in the BA community
