Information flow through strong and weak ties in intraorganizational social networks

Abstract

Strong and weak ties are compared in terms of their contributions to information flow about the work activity of persons in intraorganizational social networks. Strong ties are more important than weak ties in promoting information flow about activities within an organizational subsystem. Weak ties are more important than strong ties in promoting information flow about activities outside an organizational subsystem. The strength of weak ties in promoting boundary-spanning information flows lies not in their individual efficiency but in their numbers. In general, production of the highest probabilities of information flow is associated with a combination of both weak and strong ties.
