Video Description

This lesson covers the channels and methods of communication. In this lesson, the instructor gives examples on the whiteboard of how use a formula to calculate the number of channels of communication N x (N-1)/ 2. In communication, the sender encodes a message and sends to the receiver who then decodes it (remember there is also noise in this process) and gives feedback. Methods of communication are:

  • Push

  • Pull

  • Interactive

[toggle_content title="Transcript"] I went on the whiteboard to show how to calculate communication channels. This is kind of complicated by me just looking at the formula. It's a representing how many people. N times n minus 1 divided by 2. Kind of simple if you plug in the numbers. If you have one person, its 1 times 1 less than one person divided by two. That gives me zero communication channels. If you have two people its two times one cause its two times one number less than what I have, divided by two. That gives me one communication channel. An example is I have two people, one-two, and I have one communication channel. If I have three people now, so it is three time two, divided by two. So three times two is six divided by two, gives you three people. One-two-three then I have 3 communication channels one-two-three. If I have four people, now its four times three which is twelve divided by two, that gives me six communication channels. This is where it starts getting a little more complicated. I have to draw lines between each person, I have one-two-three four people. If I count it I have one communication channel between one and three, one communication channel between one and four, one between one and two. Right now am at three, and if I look at two, I have a communication channel between two and three, and two and four, that's is four and five and I have a communication channel between three and four that's six. If I have five people, now its five times four, which is twenty divided by two so I have ten. This is the last I want to draw because it is complicated. I have five people. One-two-three-four-five. One person has to be able to talk to two-three-four and five. One channel there, one channel between three, one channel between five, one channel between four, and then I continue with doing that with two. That include any previous communication channels. If you count them there are ten communication channels. One-two-three-four-five-six-seven-eight-nine and ten. If you continue going on with six people, six times five, divided by two which gives you fifteen. Questions that they will ask you on the exam, they might you specifically, how many communication channels do I have. Between four people the answer will be six. The exam can be tricky though. Sometimes they will include the project manager, sometimes lets say I have five people that the project manager, the project manager has five people working for him. so you are going to think five people but its five plus the project manager so its six people. Other ways they can ask the question is, I currently have two people on the project. If I add two more people gives me four people. How many communication channels have increased? With two people its four communication channels, with four people its six communication channels. It will be six minus one giving you five communication channels added. 90 percent of the project managers' time is done with communicating. In this picture, it basically shows a sender and a receiver. As a project manager you have to understand that when you send the message, you are encoding it. The receiver is decoding it and how that message gets there is in a medium. The medium is how you translate that message whether it is email, or actually talking face to face. As the sender sends this message and encodes it, there is noise there, the message gets sent to the receiver, there is also noise. The receiver might not understand everything the sender is sending his encoding goes through a medium, the receiver has to decode it and there is noise around. As the project manager 90 percent dealing with communication, you have to understand that. The sender will be receiving feedback from the receiver indicating that the receive understands what the message was sent. The last thing to understand for communication methods is push, pull and interactive. Under pushing, I am sending information out there. It is not interactive. I am possibly sending out a mass email or something where I am not receiving feedback but am putting a lot of information out. Pulling, can be like, I am gathering information from the website, so I don't have someone specific telling me something, I am not providing feedback but I am gathering information from something. An interactive is a two-way conversation. If you can remember that picture from that last slide, where two people were talking, that would be interactive. [/toggle_content]
