  • Social network analysis [SNA] is the mapping and measuring of relationships   and flows between people, groups, organizations, computers, URLs, and other connected information/knowledge   entities. The nodes in the network are the people and groups   while the links show relationships or flows between the nodes. SNA provides   both a visual and a mathematical analysis of human relationships. Management consultants use this methodology with their business clients and call it Organizational Network Analysis [ONA].

  • To understand networks and their participants, we evaluate the location of actors in the network. Measuring the network   location is finding the centrality of a node. These measures give us insight into the various roles and groupings in a network -- who are the connectors, mavens, leaders, bridges, isolates, where are the clusters and who is in them, who is in the core of the network, and who is on the periphery?

  Brief introduction to social network analysis.

  cck11 socialnetworks

  • Social network analysis [SNA] is the mapping and measuring of relationships   and flows between people, groups, organizations, computers, URLs, and other connected information/knowledge   entities. The nodes in the network are the people and groups   while the links show relationships or flows between the nodes. SNA provides   both a visual and a mathematical analysis of human relationships. Management consultants use this methodology with their business clients and call it Organizational Network Analysis [ONA].
  • To understand networks and their participants, we evaluate the location of actors in the network. Measuring the network   location is finding the centrality of a node. These measures give us insight into the various roles and groupings in a network -- who are the connectors, mavens, leaders, bridges, isolates, where are the clusters and who is in them, who is in the core of the network, and who is on the periphery?
  • Degree Centrality
  • Social network researchers measure network activity for a node by using   the concept of degrees -- the number of direct connections a node has.   In the kite network above, Diane has the most direct connections in the   network, making hers the most active node in the network. She is a 'connector' or 'hub' in this network. Common wisdom in personal networks is "the more connections, the better."   This is not always so. What really matters is where those connections   lead to -- and how they connect the otherwise unconnected! Here Diane   has connections only to others in her immediate cluster -- her clique.   She connects only those who are already connected to each other.

  • Betweenness Centrality

     

    While Diane has many direct ties, Heather has few direct connections   -- fewer than the average in the network. Yet, in may ways, she has one   of the best locations in the network -- she is between two important constituencies. She plays a 'broker' role in the network. 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. Without her, Ike and Jane   would be cut off from information and knowledge in Diane's cluster. A   node with high betweenness has great influence over what flows -- and does not -- in the network. Heather may control the outcomes in a network. That is why I say, "As in Real Estate, the golden rule of networks is: Location, Location, Location."

  • Closeness Centrality

     

    Fernando and Garth have fewer connections than Diane, yet the pattern   of their direct and indirect ties allow them to access all the nodes in   the network more quickly than anyone else. They have the shortest paths   to all others -- they are close to everyone else. They are in an excellent position to monitor the information flow in the   network -- they have the best visibility into what is happening in the network.  
  • Network Centralization
  • A very   centralized network is dominated by one or a few very central nodes. If   these nodes are removed or damaged, the network quickly fragments into   unconnected sub-networks. A highly central node can become a single point of failure. A network centralized around a well connected hub can fail abruptly if that hub is disabled or removed. Hubs are nodes with high degree and betweeness centrality.
  • Networks of low centralization fail gracefully.

  • Not all network paths are created equal. More and more research shows that the shorter paths in the network are more important. Noah Friedkin, Ron Burt and other researchers have shown that networks have horizons over which we cannot see, nor influence. They propose that the key paths in networks are 1 and 2 steps and on rare occasions, three steps. The "small world" in which we live is not one of "six degrees of separation" but of direct and indirect connections < 3 steps away. Therefore, it is important to know: who is in your network neighborhood? Who are you aware of, and who can you reach?

     

    In the network above, who is the only person that can reach everyone else in two steps or less?

  • Boundary Spanners

     

    Nodes that connect their group to others usually end up with high network metrics. Boundary spanners such as Fernando, Garth, and Heather are more central in the overall network than their immediate neighbors whose connections are only local, within their immediate cluster. You can be a boundary spanner via your bridging connections to other clusters or via your concurrent membership in overlappping groups.

      

    Boundary spanners are well-positioned to be innovators, since they have access to ideas and information flowing in other clusters. They are in a position to combine different ideas and knowledge, found in various places, into new products and services. 

  • Peripheral Players

     

    Most people would view the nodes on the periphery of a network as not being very important. In fact, Ike and Jane receive very low centrality scores for this network. Since individuals' networks overlap, peripheral nodes are connected to networks that are not currently mapped. Ike and Jane may be contractors or vendors that have their own network outside of the company -- making them very important resources for fresh information not available inside the company!
