According to study results released by Cisco, users of video conferencing receive both quantitative and qualitative benefits from the technology. It also sets out to explain why there may be hesitation to use this collaborative tool. TMCnet reports:

The biggest barriers to adoption of video collaboration, the study found, are not technology limitations but rather lack of experience and/or lack of understanding about how benefits outweigh costs. People who regularly use this technology are generally eager to extol its benefits, and overwhelmingly say it is worth the cost. Yet those who do not use it have a hard time understanding why it would benefit them. It truly is a case of seeing-is-believing.

“Ninety percent of those who use video conferencing technologies once or more per week say video collaboration technologies save them at least 2 hours of valuable work time a week—yet only 33 percent of nonusers believe they could save any time using the technology,” Cisco said in a report about the study.
