Social network analysis (SNA) is the mapping and measuring of relationships and flows between people, groups, organizations, animals, computers or other information/knowledge processing 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). A method to understand networks and their participants is to evaluate the location of actors in the network. Measuring the network location is finding the centrality of a node. These measures help determine the importance, or prominence, of a node in the network. Network location can be different than location in the hierarchy, or organizational chart. We look at a social network, called the "Kite Network" (see above), developed by David Krackhardt, a leading researcher in social networks. Two nodes are connected if they regularly talk to each other, or interact in some way. For instance, in the network above, 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 network measures: Degree Centrality, Betweenness Centrality, and Closeness Centrality.

Communities of Practice Posted on March 13th, 2009 by Harold Jarche I'm reviewing my resources on communities of practice and synthesizing some of the articles I've come across and added to my social bookmarks or blogged about on my Communities Thread. One of the best sources of practical knowledge on online community building is Anecdote from Australia. In Building a Collaborative Workplace, they discuss three types of collaboration - Team, Community and Network. As they say, "Our purpose is to provide an understanding of the type of culture required to support collaboration."

Etienne Wenger is one of the founding fathers of Social Learning Theory and the concept of "Practiced Communities". People are learning together - every individual deals and engage in many different communities of practice. Here people negotiate and define what competence and knowledge is. To know something or to be competent builds on the individuals experiences of being in the world - learning is a constant transformation or journey of the self.

Yochai Benkler's wealth of nations book online Next Chapter: Part I: The Networked Information Economy » read paragraph Chapter 1: Introduction: A Moment of Opportunity and Challenge 1 Information, knowledge, and culture are central to human freedom and human development. How they are produced and exchanged in our society critically affects the way we see the state of the world as it is and might be; who decides these questions; and how we, as societies and polities, come to understand what can and ought to be done. For more than 150 years, modern complex democracies have depended in large measure on an industrial information economy for these basic functions. In the past decade and a half, we have begun to see a radical change in the organization of information production. Enabled by technological change, we are beginning to see a series of economic, social, and cultural adaptations that make possible a radical transformation of how we make the information environment we occupy as autonomous individuals, citizens, and members of cultural and social groups. It seems passé today to speak of "the Internet revolution." In some academic circles, it is positively naïve. But it should not be. The change brought about by the networked information environment is deep. It is structural. It goes to the very foundations of how liberal markets and liberal democracies have coevolved for almost two centuries.

ABSTRACT Communities of practice consist of people who are informally as well as contextually bound by a shared interest in learning and applying a common practice. Their focus on learning, competence, and performance bridges the gap between organizational learning and strategy topics and generates new insights for theory and practice. This paper outlines the rationale for a competence-based view of organizations and proposes a community-of-practice approach to address a number of important business challenges: mergers and acquisitions, leveraging and stretching competence across functions and SBUs, accelerating innovation, business-unit disaggregation, and outsourcing.
