9.3 Virtual team collaboration

Virtual team collaboration can be grouped into two approaches: asynchronous 
and synchronous.

Asynchronous. Asynchronous collaboration occurs when two or more parties work on an activity at different times. Asynchronous collaboration techniques include document storage and retrieval, electronic voting activities, wiki repositories, email, and threaded discussions.

Synchronous. Synchronous collaboration activities occur when two or more parties share, view, or manipulate the same content at the same time. Synchronous collaboration techniques include presentation sharing, webinars, application sharing, and instant messaging.
