Being effective

Effective communication, and therefore effective business, is an essential component of organizational success whether it is at the interpersonal, intergroup, organizational, or external levels. The ability to communicate is a key factor in continued success within the organization.
Communicating is always to two-way process. In management, you communicate to get things done, pass on and obtain information, reach decisions, achieve joint understanding, and develop relationships.
Effective communication (and therefore effective business) hinges on people understanding your meaning, and replying in terms that move the exchange forward - preferably in the direction you would like it to go.

Recogninzing barriers

There are always at least two parties involved in any communication, each of whom may have different wants, needs, and attitudes. And there are a wide number of sources of noise or interference that can enter into the communication process. These wants and needs can present barriers if they conflict with those of the other party, and such barriers may stop you conveying or receiving the right message.
