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]

Video Transcription

00:04
So I went in the whiteboard that show how to calculate communication channels.
00:08
This could look kind of complicated. We're just looking at the formula, but it's n representing how many people.
00:15
So it's end times and minus one, divided by two
00:19
kind of simple. If you plug in the numbers,
00:22
you have one person.
00:24
It's one times
00:26
one less than one person said zero
00:29
divided by two.
00:30
That gives me zero communication channels,
00:33
and I'll be ableto display this in a minute.
00:37
If you have two people, it's two times one because it's two times one number less than one. Um, what I have
00:45
divided by two
00:47
and that gives me one communication channel.
00:51
So an example is I have two people 12
00:54
and I have one communication channel
00:59
if I have three people now,
01:00
so it's three times two,
01:03
divided by two. So three times two is six. Divided by two
01:07
gives you three.
01:07
So here's an example of three people. 123
01:11
and I have three communication generals. 123
01:18
Now, if I have four people now, it's four times three, which is 12 divided by two. That gives me six communication channels This is where it starts
01:27
getting a little more complicated. So have to draw lines between each person. So I have 1234 people.
01:34
And if I count it, I have
01:37
one communication channel between one and 31 communication channel between one and four.
01:42
One between one and two.
01:44
Sorry. Now let three.
01:46
Then if I like it too,
01:48
I have a communication channel between two and three
01:52
and two and four.
01:53
So that's 45
01:56
And
01:57
I have a communication channel between
02:00
three and four. Such six.
02:04
If I have, ah,
02:06
five people now, it's five times for what's this one and divided by two. So I have 10.
02:12
This is the last one I'm gonna draw out because it gets complicated. So
02:15
I have five people 12
02:19
345
02:20
so that one person has to be able to talk to 234 and five. So
02:27
one channel there,
02:29
one channel between
02:30
31 channel between 51 channel between four.
02:36
And then I continue that with doing that with two not including any previous communication channels.
02:42
If you count on,
02:43
there are, um, 10 communication channels. So
02:46
one,
02:49
234
02:51
56
02:53
789 10.
02:58
And, uh,
02:59
if you continue going on with six people, it's six times five divided by two. What's gives you 15
03:05
um,
03:06
questions that they will ask you on the exam so they might ask you specifically,
03:10
How many communication channels do I have between
03:14
four people? See? Answer would be six.
03:17
The exam can be tricky, though, so sometimes they will include the project manager.
03:23
Sometimes they'll say, like I have five
03:27
people that the project manager at the Project Winter has five people that work for him.
03:32
So you're gonna think five people, but it's five plus the project manager, so it's six people.
03:38
Um, other ways that can ask the question
03:42
is,
03:43
I currently have
03:45
two people on the project.
03:47
If I add
03:50
two more people giving me
03:51
four people,
03:53
how many communication channels have increased well with two people? It's only one communication channel
03:58
with four people at six communication channels, so it would be six minus one, giving you five communication channels. So 90% of the project managers time is dealt with communicating
04:10
this picture. It basically shows a sender and receiver.
04:15
As the project manager, you have to understand that
04:17
when you send a message, you're encoding it,
04:20
the receiver is decoding it.
04:23
And how that message gets there
04:25
isn't a median.
04:27
The median is how you're transmitting that message, whether it's email or
04:30
actually talking face to face
04:34
as the sender
04:36
sends this message and encourage it,
04:39
Um,
04:40
there's noise there,
04:44
so that message gets sent to the receiver.
04:47
There is also noise, so the receiver might not understand everything that the sender
04:51
is, ah, sending because
04:54
he's encoding
04:56
goes through a median,
04:58
the receiver has to decode it,
05:00
and there's no is involved.
05:01
So as a project manager
05:03
with 90% of the time dealing with communication, you have to understand that.
05:08
And, ah,
05:09
this Sunder will be receiving feedback
05:13
from the ah receiver
05:15
indicating that the receiver understands what the message was. Uh, what the message was sent.
05:21
The last thing to understand for communication methods is push pull and interactive
05:29
under um, pushing. I am sending information out there.
05:32
It's not interactive.
05:34
I am possibly sending out a mass email or something where I'm not receiving feedback, but I'm putting a lot of information out.
05:46
Polling
05:46
could be,
05:47
um, I am gathering information from like a website.
05:51
So I don't have someone specifically telling me something. I'm not providing feedback,
05:56
but I am gathering information from something.
05:59
An interactive is two way conversation. So if you remember the picture from the last slide,
06:04
um,
06:06
where two people are talking, I'd be interactive.
