This type of communicating is usually our first choice whenever we have the need for effective communication. Whenever one gives a speech or presentation, oral communication is being used. It is important that one's communication skills are above average in this situation because of the impact they will often have on the audience. Oral communication can also occur over the telephone. It is also interactive between the sender and the receiver.
Many people still prefer written verbal communication over oral communication.
Indeed, this type of communication is preferred when the message being sent is clear. Memos are used internally by organizations to inform employees about changes or upcoming events occurring in the organization. Newsletters are also internal documents which describe information of interest to employees regarding business and nonbusiness issue. They often improve employees' morale and productivity because the employees feel as though the company cares enough to communicate with them. Posters are very static, but let many people know about upcoming events quickly.
