[SOUND] The third principle of effective communication is completeness. What does completeness mean? Your messages, whether spoken or return formal or informal must be complete. That means your messages should have all the facts required for the intended receiver to understand your message. The sender of the message must also take into consideration, the receiver's mindset. So, how do you think the receiver will interpret the message? So, think about the recipient, think about the facts the recipient has. Think about how the recipient will interpret this message. If you're able to produce a complete message, the message will increase the reputation, your reputation, you as a worker. You as a member of an organization, and also, you represent your organization. So, you will give the organization a good name. It will potentially save cost, because you are saving time and you are preventing mistakes from happening. It will definitely speed up the decision making process. And you are very importantly, being very informative and persuade your audience to do what you want them to do. Okay, let's have a look at the not so good example of completeness in the third situation. Christine writes, dear all, let us meet tomorrow to discuss the product launch event. Please be there on time. Can we write dear all? What do you think? Can we write Dear All? Well, it would be acceptable to write dear all, if your recipients know that you're addressing to him or her. Okay, very precisely. Second point, let us meet tomorrow. When tomorrow? You've got to be very careful in using words like tomorrow. Because if the recipient does not get the message until the next day, then what does the tomorrow mean? So then, the recipient of this message will have to clarify firstly when. Tomorrow and what the tomorrow is. So, you need to be more precise there, please be there on time. Be where and what does on time mean? What time and where? So, these are the flaws with this message, it's not complete. The recipient, or recipients, of this message would not know how to act on that action. A good message would allow the recipient to take action without any clarification. So, this is not a very good. Okay now, let's compare example A with this example. Example B, is a better version of example A. The writer, Christine, says, dear all, so again, assuming the recipients know that you're addressing to every person who should receive this message. Let us meet tomorrow, so don't just say tomorrow. But actually insert the date as well, and the time, at 11 AM at the Annex building. So, it says the place as well. The building also has many floors presumably, so say the room and the level number. So, 03-03, so probably third floor, and room 03. "To discuss the product launch event. We will have to decide the keynote speakers and complete the event invitation draft tomorrow. So, before the recipient go to the meeting, the recipient will know not only when and where to meet, but also the content of the meeting. The agenda of the meeting, so this will allow the recipients of this message to prepare for the meeting. And to know what to expect about the meeting. So, the meeting in this case is about keynote speakers. And the event, having to complete the event invitation draft. So, this is a very precise message, and is complete, so people can act on this message. I look forward to meeting you tomorrow. While this is not necessary, it's a polite thing to say at the end of your message. Tell people that you're looking forward, that you're happy to be working with them.
