Which communication channel is generally considered the richest medium?

Question

Accepted Answer

Face-to-face conversation. Face-to-face conversation is the richest communication medium because it conveys the most information per communication episode. It allows for immediate feedback, includes both verbal and nonverbal cues (tone, facial expressions, body language, gestures), and enables the sender and receiver to adjust their messages in real time.

Written memos are lean media that convey only the text content - they lack nonverbal cues, immediate feedback, and personal focus, though they are useful for formal documentation. Email is richer than memos because it can be more informal and allows relatively quick back-and-forth, but it still lacks nonverbal cues and the immediacy of face-to-face interaction. Bulletin board postings are among the leanest communication channels, offering one-way communication with no immediate feedback and no personalization.

Media richness theory, developed by Daft and Lengel, is an important communication concept on the DSST exam. The theory suggests that managers should match the richness of the communication channel to the complexity and ambiguity of the message. Routine, clear messages can be communicated through lean media, while complex, ambiguous, or emotionally sensitive messages require richer channels.
