Managers usually prefer oral communication to written communication.
Although oral communication suffers from some drawbacks, this method of communication is more effective than written communication in the following 8 situations:
Oral communication is more effective when it is needed to communicate with someone instantly.
Detailed Explanation of Policies
If any direction of managers and policy or procedure of the company requires explanation, oral communication is the best way to communicate.
Developing Direct Relationship
If it is important to establish direct relationship between sender and receiver, or between workers and management, they should communicate orally.
Oral communication is best suited when information is to be kept secret. Written communication leaks secrecy as the message passes from hand to hand.
Where instant reply from the receiver is required, oral communication is the best suited there.
Reaching To Mutual Understanding
Sometimes open discussion is needed for reaching to a consensus. Such discussion is possible only through oral communication.
When the receivers are illiterate, written communication is meaningless to them. Oral communication is only the way to communicate with them.
Avoiding Bureaucratic Complexities
Bureaucratic complexity delays the communication. In order to avoid any delay caused by bureaucracy or red-tapism, oral communication should be used instead of written communication.
