Video helps remote work

More and more organizations are forming teams that are not co-located. These teams communicate via email, fax, telephone and audio conferences, and sometimes video. The question often arises whether the cost of video is worth it. Previous research has shown that video makes people more satisfied with the work, but it doesnt help the quality of the work itself. There is one exception; negotiation tasks are measurably better with video. In this study, we show that the same effect holds for a more subtle form of negotiation, when people have to negotiate meaning in a conversation. We compared the performance and communication of people explaining a map route to each other. Half the pairs have video and audio connections, half only audio. Half of the pairs were native speakers of English; the other half were non-native speakers, those presumably who have to negotiate meaning more. The results showed that non-native speaker pairs did benefit from the video; native speakers did not. Detailed analysis of the conversational strategies showed that with video, the non-native speaker pairs spent proportionately more effort negotiating common ground.
