Our messages can get lost (mis-communication) in the mind of our receiver (audience) because of barriers. However, here are three characteristics that can help to make your message more effective. 1) Your message must be appropriate - according to the audience, subject, needs of the receiver and environment. 2) Your message must be useful - ask yourself "Is my information needed by my audience? How much do they know? How much might they want to know?" 3) Your message must be persuasive - Use the psychology and tactics of Appeals to make your message more effective to the audience. First, know your objective for communicating; then, analyze the audience according to what we know about them as individuals or as a group; and then choose the proper organization of your information according to the type of audience they are (or the majority of the audience will be) either Hostile, Friendly, or Indifferent.
