[SOUND] Let's have that look at the six principles of communication. Coherence, so what is coherence? Coherence means it's logical. What you say at the beginning, what you say throughout your message, and what you say at the end of your message must be linked to the same topic. So if you have a main idea, all the details must be relevent to that main point. Don't get distracted and include other information in your message, otherwise it will create confusion. Okay, so other than the topic, the content, having to be logical from the beginning and all through to the end, the tone that you use must also be consistent, must also be logical. So if you're formal at the beginning, then you should, in the message, formally all the way until the end. The flow of the text must also be consistent so the language that you use and the tone, whether it's formal or informal, must also be consistent. So in doing so, you will be able to save time. You won't cause any confusion and prevents misunderstanding in your message between you and your audience. So very important to make sure you build logical flow within your message. Okay, now let's read an example of an incoherent message. So Vincent writes to Zack and says that, dear Zack, thanks for submitting the third quarterly progress report for the Western Hill Project. Finn will email you detailed comments. Upon completion in the third quarter, Finn will contact you to arrange a date to discuss the budget for the fourth quarter so the client can move on to complete the final stage of the project. Now can you see the content of this match is incoherent? Vincent writes to Zack and starts off by saying, about talking about the third quarterly progress report, then says Finn will email you, so it's so far so good. But then in the next part of the message, Vincent says Finn will contact him about the budget. What does the detailed comments have to do with the budget. So either Vincent should mention about only the feedback for Zack, or mention about the budget. So the focus of this message is not clear. And if there is a relationship between the comments and the budget then Vincent would have to link how the two paths relate. So is it because Finn will give feedback to Zack and based on the feedback they can then move on to talk about the budget. If that is the case then Vincent would have to explicitly say so. Vincent can not assume Zack, the receiver of the message, can draw the link between the two parts of this message because of this message, because they don't relate. You need to say so, okay? So let's have a look at a better example of this message. Okay, now let's have a look at a more coherent version of the same message. Vincent writes to Zack and says Dear Zack, thanks for submitting the third quarterly progress report for the Western Hill Project. Finn will give you some feedback on it by, and provides the date and time if possible. After we finalize the progress report, we will arrange to meet to discuss the budget and complete the final stage of the project. Regards, Vincent. So can you see how this message is better linked? Vincent starts by thanking Zack for the progress report. Then the next step is Finn will give feedback. After Finn gives feedback and finalize the progress report, then they will met to talk about the budget and then the completion of the final project will take place. So the relationship between progress reports, feedback and the budget are all linked coherently. So you need to make sure you explicitly say so, how ideas relate to each other in words.
