According to Media Richness Theory, which of the following digital communication tools provides the lowest level of richness for resolving a highly ambiguous emotional conflict between two team members?

Media richness refers to the ability of a medium to convey multiple cues (tone, body language) and provide immediate feedback. An automated no-reply email is the leanest possible medium as it provides no cues and zero opportunity for feedback and is completely impersonal.   ·        A high-definition Zoom call is a high-richness medium. It provides immediate feedback, visual cues (facial expressions), and audio cues (tone), making it ideal for resolving conflict. ·        A personalized recorded video message, while asynchronous, it still provides high cue variety (visual and audio), which ranks it higher in richness than text-based or automated messages. ·        A synchronous Instant Messaging (IM) chat provides rapid feedback, which increases richness compared to static emails, though it still lacks visual and audio cues. ·        A collaborative project management dashboard, while lean, these are typically used for routine data and tracking.   However, an automated no-reply email is even leaner because it is strictly one-way and contains no interactive or collaborative elements
