Media Richness Theory
During reading paper in HRD, I found this theory.
“Media Richness Theory” founded by Daft and Lengel(1984) and based on the idea that ‘media has different capability of delivering information’. Richness means the amount and quality of information of media.
Based on these idea, face-to-face communication is the richest medium due to personal focus — e.g. immediate feedback, multiple cues.
