A consumer goods company holds quarterly meetings involving its three dozen sales managers. These managers are located in several cities and countries, so more than half of them "participate" in the meeting as remote attendees. The one-day meeting has an opening and closing talk by CEO and vice president of sales, but most of the day consists of open discussion as well as one small-group session on strategic and operations sales issues. Which digital communication channel(s) would likely work best for involving the remote participants in these sessions? You may assume that more than one digital channel can be used throughout the day and, for some channels, more than one channel may be used at the same time. Your answer should refer to the four factors to consider when choosing the best communication channel (synchronicity, social presence, social acceptance, and media richness)
