Diagonal communication cross units – UGC NET Question

Diagonal communication takes place when messages cross both functional departments and hierarchical levels. A librarian belongs to the library section,while the finance officer is in another administrative unit. Direct communication between them bypasses normal vertical channels,which is typical of diagonal communication.

Option A:
Upward communication would involve the librarian writing to their immediate superior rather than to another department.

Option B:
Horizontal communication would occur between colleagues of the same unit and level,such as librarians coordinating with each other.

Option C:
Thus diagonal communication correctly describes this cross unit, cross level internal contact.

Option D:
External communication refers to contacts with people outside the university,such as vendors,not internal finance officers.
