In order to better understand the communication process, we can break it down into a series of eight essential components.
- Source
- Message
- Channel
- Receiver
- Feedback
- Environment
- Context
- Interference
Each of these eight components serves an integral function in the overall process.
Source
The source imagines, creates, and sends the message. In a public speaking situation, the source is the person giving the speech. He or she conveys the message by sharing new information with the audience. The speaker also conveys a message through his or her tone of voice, body language, and choice of clothing. The speaker begins by first determining the message—what to say and how to say it. The second step involves encoding the message by choosing just the right order or the perfect words to convey the intended meaning. The third step is to present or send the information to the receiver or audience. Finally, by watching for the audience’s reaction, the source perceives how well they received the message and responds with clarification or supporting information.
Message
The message is the stimulus or meaning produced by the source for the receiver or audience. The message also consists of the way you say it—in a speech, with your tone of voice, your body language, and your appearance—and in a report, with your writing style, punctuation, and the headings and formatting you choose.
Imagine, for example, that you are addressing a large audience of sales reps and are aware there is a World Series game tonight. Your audience might have a hard time settling down, but you may choose to open with, “I understand there is an important game tonight.” In this way, by expressing verbally something that most people in your audience are aware of and interested in, you might grasp and focus their attention.
Channel
The channel is the way in which a message or messages travel between source and receiver.
For example, think of your television. How many channels do you have on your television? Each channel takes up some space, even in a digital world, in the cable or in the signal that brings the message of each channel to your home. Television combines an audio signal you hear with a visual signal you see. Together they convey the message to the receiver or audience. Turn off the volume on your television. Can you still understand what is happening? Many times you can, because the body language conveys part of the message of the show. Now turn up the volume but turn around so that you cannot see the television. You can still hear the dialogue and follow the storyline.
Similarly, when you speak or write, you are using a channel to convey your message. Spoken channels include face-to-face conversations, speeches, telephone conversations and voice mail messages, radio, public address systems, and voice over Internet protocol (VoIP). Written channels include letters, memorandums, purchase orders, invoices, newspaper and magazine articles, blogs, e-mail, text messages, tweets, and so forth.
Receiver
The receiver receives the message from the source, analyzing and interpreting the message in ways both intended and unintended by the source.
To better understand this component, think of a receiver on a football team. The quarterback throws the football (message) to a receiver, who must see and interpret where to catch the ball. The quarterback may intend for the receiver to “catch” his message in one way, but the receiver may see things differently and miss the football (the intended meaning) altogether.
As a receiver you listen, see, touch, smell, and/or taste to receive a message. Your audience “sizes you up,” much as you might check them out long before you take the stage or open your mouth. The nonverbal responses of your listeners can serve as clues on how to adjust your opening. By imagining yourself in their place, you anticipate what you would look for if you were them. Just as a quarterback plans where the receiver will be in order to place the ball correctly, you too can recognize the interaction between source and receiver in a business communication context. All of this happens at the same time, illustrating why and how communication is always changing.
Feedback
When you respond to the source, intentionally or unintentionally, you are giving feedback. Feedback is composed of messages the receiver sends back to the source. Verbal or nonverbal, all these feedback signals allow the source to see how well, how accurately (or how poorly and inaccurately) the message was received. Feedback also provides an opportunity for the receiver or audience to ask for clarification, to agree or disagree, or to indicate that the source could make the message more interesting. As the amount of feedback increases, the accuracy of communication also increases.
For example, suppose you are a sales manager participating in a conference call with four sales representatives. As the source, you want to tell the representatives to take advantage of the fact that it is World Series season to close sales on baseball-related sports gear. You state your message, but you hear no replies from your listeners. You might assume that this means they understood and agreed with you, but later in the month, you might be disappointed to find that very few sales were made. If you followed up your message with a request for feedback (“Does this make sense? Do any of you have any questions?”) you might have an opportunity to clarify your message, and to find out whether any of the sales representatives believed your suggestion would not work with their customers.
Environment
The environment is the atmosphere, physical and psychological, where you send and receive messages. The environment can include the tables, chairs, lighting, and sound equipment that are in the room. The room itself is an example of the environment. The environment can also include factors like the formal dress, which may indicate whether a discussion is open and caring or more professional and formal. People may be more likely to have an intimate conversation when they are physically close to each other, and less likely when they can only see each other from across the room. In that case, they may text each other, itself an intimate form of communication. The choice of text is influenced by the environment. As a speaker, your environment will impact and play a role in your speech. It’s always a good idea to go check out where you’ll be speaking before the day of the actual presentation.
Context
The context of the communication interaction involves the setting, scene, and expectations of the individuals involved. A professional communication context may involve business suits (environmental cues) that directly or indirectly influence expectations of language and behaviour among the participants.
A presentation or discussion does not take place as an isolated event. When you came to class, you came from somewhere. So did the person seated next to you, as did the instructor. The degree to which the environment is formal or informal depends on the contextual expectations for communication held by the participants. The person sitting next to you may be used to informal communication with instructors, but this particular instructor may be used to verbal and nonverbal displays of respect in the academic environment. You may be used to formal interactions with instructors as well, and find your classmate’s question of “Hey Teacher, do we have homework today?” as rude and inconsiderate when they see it as normal. The nonverbal response from the instructor will certainly give you a clue about how they perceive the interaction, both the word choices and how they were said.
Context is all about what people expect from each other, and we often create those expectations out of environmental cues. Traditional gatherings like weddings or quinceañeras are often formal events. There is a time for quiet social greetings, a time for silence as the bride walks down the aisle, or the father may have the first dance with his daughter as she is transformed from a girl to womanhood in the eyes of her community. In either celebration, there may come a time for rambunctious celebration and dancing. You may be called upon to give a toast, and the wedding or quinceañera context will influence your presentation, timing, and effectiveness.
In a business meeting, who speaks first? That probably has some relation to the position and role each person has outside the meeting. Context plays a very important role in communication, particularly across cultures.
Interference
Interference, also called noise, can come from any source. Interference is anything that blocks or changes the source’s intended meaning of the message. For example, if you drove a car to work or school, there are chances that you were surrounded by noise. Car horns, billboards, or perhaps the radio in your car interrupted your thoughts or your conversation with a passenger.
Psychological noise is what happens when your thoughts occupy your attention while you are hearing, or reading, a message. Interference can come from other sources, too. If you are hungry, your attention to your current situation interferes with your ability to listen.
Noise interferes with the normal encoding and decoding of the message carried by the channel between source and receiver. Not all noise is bad, but noise interferes with the communication process. For example, your cell phone ringtone may be a welcome noise to you, but it may interrupt the communication process in class and bother your classmates.
