Horizontal communication examples include team meetings and peer-to-peer discussions. Diagonal communication can be seen in task forces involving members from different departments and levels.
Horizontal communication may face barriers like interdepartmental rivalry. Diagonal communication faces challenges like power dynamics and differences in jargon or priorities across departments.
