This paper focuses on private sources of knowledge specifically customers and competitors as sources of innovative activity. Our main argument is that the two sources are correlated even after controlling for several factors at the level of technology, individual and organization. What is more, we show that the geographical distance of these sources modifies the intensity of this correlation, i...

This empirical study focuses on the impact of an information technology (IT), specifically electronic mail (e-mail), on three basic organization components: structure, people, and tasks. An Organizational Interaction Diamond (OID) model is developed illustrating how each component enables changes in other components interacting with the organization’s internal and external environments. The org...
