Abstract Two studies used 90 small, well-established decision teams to examine the effects of a one-time use of audioconferencing on group decision performance and status structure across two different problem-solving tasks - one intellective, the other value-laden. Audio did not affect performance or structural stability in either study. Audioconferencing groups were no more or less likely to produce high-quality solutions or to support their groups′ decisions than were face-to-face groups. Status differentiation and leader influence remained relatively stable regardless of medium. The results contradict popular wisdoms (mainly derived from studies of ad hoc groups) and provide a needed baseline for further research on EMS in established groups. The lack of disruption by audio has important practical implications.
