Trends in collaboration technologies for net-centric computing

Three main facets of CSCW research and development are: communication, coordination, and collaboration. Collaboration is the final purpose, while communication and coordination mechanisms are to provide necessary support and environment for collaboration. We broadly classify CSCW studies in two general categories: formal and informal.
