It is realistic to assume that oral communication will probably play a larger role in future business communication than it has in the past. However, it is just important to realize that writing will always be with us. Certainly the telephone is personal, immediate, and two-way, and it provides an opportunity to discuss questions or interpretations as they arise in many instances, telephoning is less expensive than writing. On other hand, a written communication leaves a the methods of permanent record to be referred to; that is why, even when oral put that in communication are used, we so often conclude by saying, "I wish you'd writing" and "I'd like to see it in black and white." A written business communication gives its writer to consider and to organize thought; it provides the chance a chance forms and styles in which the to reread and revise, and it offers a choice of various that reports or memos or message can be couched. It is foolish to think, therefore, letters will be replaced as integral parts of the communication process in business and it is absurd to use the cost of letter, for instance, as the sole reason considering at obsolete.
