Books on this subject often include the fundamentals of primary and secondary research, techniques for data analysis, and analytical and presentation graphics. These changes, especially since the advent of the computer, have altered the way we think about communication, and we have yet to see the end of these changes. Car phones, cell phones, and pagers help ensure that one can communicate from virtually anywhere to virtually anywhere else at any time, and email has recently become the principal means of exchanging written communication in organizations. As the volume of communication increases, the chance of information overload also increases, which not only reduces the impact of individual messages but also increases the need for effective communication skills, including listening, speaking, reading, and writing. Your success in life, from both a personal and a professional standpoint, will depend to a great extent on your ability to communicate.
Nothing happens without communication, without the exchange of information.
People evaluate you both formally and informally by your communication skills. We typically gauge the intelligence of others and their ability to do a given job by their use of language and other communication skills. Depending on the job, you may also be called upon to write letters and reports and to present to small groups. In general, the higher a person rises in an organization's hierarchy, the more time he or she spends communicating both formally and informally. In today's fast-paced business environment, poor communication is expensive.
