Diffusion of a collaborative technology cross distance

Gloria Mark, Steven Poltrock
2001 Proceedings of the 2001 International ACM SIGGROUP Conference on Supporting Group Work - GROUP '01  
Achieving a common set of collaboration tools is a significant challenge for people working together in a geographically distributed enterprise.  ...  In this paper, we report on the diffusion of a data conferencing technology in a large distributed enterprise. Two years ago we studied the early adopters; now the technology is widespread.  ...  Participation on some teams was voluntary and part-time. Managers did not view distance collaboration as important enough to warrant purchasing computers to run data conferencing.  ...
