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

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
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
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
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.
