CORE DEFINITION

Different media have different capacities to carry information (richness). Face-to-face communication is the richest (including expressions, tone, quick feedback), while text emails are poorer. The more ambiguous and complex the task, the higher the richness of the medium needed. Scaffolding role: matching communication channels. Prevent "using a sledgehammer to crack a nut" (holding a big meeting for a simple notice) or "a small cart pulled by a big horse" (resolving complex emotional disputes with WeChat text). Guide us to choose the right tools in the remote work era.

Media richness is determined by immediate feedback capability, multiple cues (expressions/tone), natural language use, multiple information channels, etc. The higher the task uncertainty and ambiguity, the higher the richness of the medium needed; routine tasks can use low-richness media.

MINIMUM ACTION

In progress 0/2

Practice this model in one real situation:

First judge the ambiguity/complexity of the task. For high ambiguity (e.g., conflict mediation), use face-to-face or video
for low ambiguity (e.g., notices), use email/announcements. Avoid mismatches: don't use text for major emotional topics, don't hold big meetings for simple confirmations.
