Overlapping Boards

We often think of our networks as belonging to us, or our group/team/family. We imagine they have an identifiable beginning and end. We want to draw borders to define "yours" and "mine." Yet, in reality we cannot. We really cannot define where my network stops and yours starts... no matter if you are a person, group, organization, or country. We are all intersected and our connections overlap with those of our network neighbors. Boundaries are fuzzy, at best.

Let's look at a simple example. Organizations, whether for-profit, or not-for-profit, usually have a Board of Directors. We can think of this Board as a network that belongs to the organization. All members are linked if they sit on an organization's board together. We might view the Boards of the top 50 U.S. companies like the diagram below -- individual clusters, each belonging to the parent company. The gray links show co-membership ties between the individuals.

Directors are not limited to the number of Boards they can be members of. Board members are limited to the number of Boards they sit on only by time, energy and invitation. Below is an example of a Board member who sits on the Board of two organizations. This may be Steve Jobs, who sits on the Board of Apple and Disney.

We now choose a different color for those Directors who sit on multiple Boards. We see how the Boards of the top US companies are actually interconnected in the diagram below. Blue nodes are Directors who sit on multiple Boards.

The blue nodes in the network above are conduits that move information, ideas, and knowledge between the clusters -- they are at the intersection, where two networks overlap. The blue nodes are well placed to be Network Weavers -- their opportunity to close triangles is great.

Contagion of ideas and practices between organizations often happen through flows via their Boards of Directors. We apply social network analysis [SNA] to this social graph and we see who may be key in this diffusion process. We apply a new SNA metric, called Awareness -- it measures potential awareness of a node to what is happening around it [directly and indirectly] based on it's pattern of connectivity. Those nodes with higher awareness are shown in a larger size in the diagram below.

It is usually beneficial to be connected to those who have a good view of what is going on. Information and knowledge is often shared [intentionally or unintentionally] with trusted others, close by. Information leaks and flows, but never too far. Board members who are connected to other highly-aware Board members, have a higher probability of finding out more -- but the range is limited. Even those who just sit on a single Board can increase advantage by being connected to multiple blue boundary spanners. This is reflected in the diagram below. Node size is derived from awareness of what is happening in the network. Some Boards have greater awareness of what is happening in their ecosystem.

This was a simple illustration. An actual network between the Board members will be denser, based on their possible multiple ties -- employment, memberships, and other current & past associations. The full multiplexity of the individuals was not known, nor shown. Yet, we see how even some knowledge of a social system increases our potential to target messages to influence that system. Of course, the better our data, the better our targeting. A telescope may be preferred, but even binoculars provide advantage over the naked eye. And binoculars that reveal what is usually invisible, are even more useful!

What Board overlaps can you utilize?
