Effective communication occurs when a desired effect is the result of intentional or unintentional information sharing, which is interpreted between multiple entities and acted on in a desired way. This effect also ensures that messages are not distorted during the communication process. Effective communication should generate the desired effect and maintain the effect, with the potential to increase the effect of the message. Therefore, effective communication serves the purpose for which it was planned or designed. Possible purposes might be to elicit change, generate action, create understanding, inform or communicate a certain idea or point of view. When the desired effect is not achieved, factors such as barriers to communication are explored, with the intention being to discover how the communication has been ineffective.
