Social networks can tell us a lot about how organizational structure promotes innovation. And don’t worry, this post is not about optimizing Facebook and Twitter to boost creativity. The term social network can be used to describe the relationships between any collection of two or more people, groups or organizations with common goals or interests(1).

Figure 1: Structural Holes(6) |
There are different theories as to what produces innovation in social networks. One common explanation is that the presence of structural holes, defined as places of disconnection in the network, promote creativity in the individuals nearest to the structural hole(2, 3,4). Individuals who are near structural holes are more likely to have access to diverse, often contradictory, information and interpretations because they are able to draw on information from outside of their immediate connections(2). Encouraging indirect ties that bridge structural holes is a cost effective way for organizations to access diverse knowledge and contribute to innovation without adding to project expenses(5).

Figure 2: Core Periphery Structure (12) |
So how do we bridge these two contradictory concepts? One way is through promoting a core-periphery structure. A strong project team will consist of a densely connected core of key decision makers who are loosely connected to a peripheral network form which they draw ideas and information into the network. These loose connections to the periphery network allows for the network to be larger, bringing in new and diverse ideas. Because not all members of the core are connected to the periphery, innovation producing structural holes are formed.
