Formulate the idea in your mind. You might think of something you want to relate to another person. This is the point at which the idea occurs and is the first stage of communication.
Encode the message. By encoding you put it into language or a style that will suit your message and your recipient. You would, for instance, encode a message you wish to give to a small child differently from a message you want to give to a professional colleague.
Transmit the message. You can do this by speaking, calling, writing, emailing or using one of many available communication methods.
Receive the message if you are the person the message is being given to. Listen or read the message.
Decode the message you have received. Mentally process the information into a form that makes sense to you. An example of this would be a person looking up a word in the message that he did not understand
Understand the message. This is the final step of the process and an important one. Most people recognize that messages can be sent, listened to or read, but this does not guarantee successful communication.
