customers, potential customers, suppliers, investors, shareholders, and society at large.

Formal communication refers to interchange of information officially. The flow
of communication is controlled and is a deliberate effort. This makes it possible for the information
to reach the desired place without any hindrance, at a little cost and in a proper way.
Informal communications are based on the personal or informal relations such as friends, peers,
family, club members, etc. and thus is free from the organizational conventional rules and other
formalities. Informal communication is called as a “grapevine” as it is difficult to define the
beginning and end of the communication.

transmission of information between
people, divisions, departments or units
within the same level of organizational
hierarchy.
Diagonal Communication is the
communication held between different
structures of a business firm.

diagonal communication.
