Welcome back again.
This is module 4.
An introduction to Project Management Principles and
Practices, University of California, Irvine.
And again, I'm Rob Stone.
We're still in planning.
We're going to talk about human resources.
We've put our project together now.
We've defined what the project is.
We've figured out how we're going to do this project.
Now we figure out who is going to do this.
We have to put all the people on this project.
2:40
It's almost 8 o'clock on Monday morning.
We're waiting for some information from our customer so that Ted can get to work
on a task that's important on this project and needs to be done.
We have to have this information before Ted can start on the task.
It's almost 8 o'clock Monday morning.
The phone rings.
Ted's walking in the door.
You answer your phone and say to your, say hello.
Oh, yes.
Great.
Wonderful. I'll let him know and
we'll get started on that right away.
3:06
Catch Ted when Ted comes walking in the door and
say Ted, the customer just called, they have just emailed the information to you.
You can start working on that task that we're waiting for the information for.
Can you get started on that right away?
Because they're gonna be in here at noon on Wednesday and
they need this thing done by then.
We have to have it done by noon on Wednesday.
That gives Ted eight hours on Monday to do this,
eight hours on Tuesday to work on this, and four hours on Wednesday.
There's a 20 hours.
Eight hours Monday, eight hours Tuesday,
we've got sixteen hours worth of the work done.
Do the other four hours on Wednesday morning.
So, 20 hours duration available.
And we have 20 hours of work to get done.
They're equal.
Duration is the time that we have set aside to actually accomplish work.
Now, Ted starts back down the hall and phone rings again.
Pick it up and say, hello, yes what?
Oh, yeah.
I'll let him know, not a problem.
Thank you.
Ted, hold on a second, the customer just called.
They're not gonna be here until 5 o'clock on Friday.
You don't need to have this thing done til 5 o'clock Friday.
Ted says that's great,
I can start on it right away this morning and I'll have it done by Friday.
I've got other things to do.
I can work some other work in around all of that.
I will get the 20 hours worth of work done in 40 hours.
There's eight hours on Monday, eight hours Tuesday, Wednesday, Thursday, Friday.
Each of those days has eight hours.
There's 40 hours of duration time available for Ted to do his work.
He only has 20 hours worth of work to do.
So in that case, duration is longer than the amount of work.
Now Ted starts back down the hall and the phone rings again, and you go oh, yes,
nice to talk to you again.
Oh yeah, that's not a problem at all, I'll let him know and
we'll get that worked out.
Hang up, Ted you gotta get back here quick, we got a big problem now.
All of a sudden, they're gonna be in here tomorrow morning at 10 o'clock.
What are we gonna do?
Ted says, that's not a problem.
There's only 20 hours worth of work to do on this.
Jill just finished up a project and I said, hey I might need some help on this
project that I'm working on, would you be available?
And she said yes, I can help you with that.
I'll go, let Jill know right away that we both need to start working on this,
this morning right away at 8 o'clock.
Ted and Jill both work on this task for
eight hours on Monday, sixteen hours worth of work gets done on Monday.
5:15
We still have four hours worth of work to do.
And between 8 and 10 o'clock on Tuesday, we only have two hours duration.
But Ted and Jill are both gonna work two hours.
So we get four hours of work done then between now 8 o'clock on Monday morning
and 10 o'clock on Tuesday morning, we get the 20 hours worth of work done.
In that case, the amount of work is longer than the duration available.
These are the three ways that work and duration relate to each other.
And this is how you start to figure out the duration on your project tasks.
If you want a task to go faster, usually we can put some more people on there and
it will go faster.
It might not always go as fast as we want.
Sometimes putting more people on there slows things down a little bit because
people just get in each others way a little.
But putting more people on a task, typically will get it done faster.
6:39
Instead of a day being 24 hours, no, it's eight hours.
We've converted elapsed time into duration time and
said this is the time we've set aside to do work.
So it can be four ten-hour days or however you have it set up in your organization.
What we said, these are the times available to do work.
During that duration, we can get more or less work done on the,
one of these little bars across here.
You'll see they're pretty tall.
That means that on Thursday and Friday, we had some people working.
And so we got more than eight hours worth of work done on the task.
On Wednesday that one week,
we got less than eight hours of work done on that task.
Weekend, we got nothing done on that task.
When you talk to people about how long it's gonna take to do the project, you
need to find out what people are talking about and what terms they're using.
What do people wanna know when they say, when's the project gonna be done?
They're only caring about elapsed time,
they just wanna know the date on the calendar and the time on the clock.
They don't care about work and duration, the only way that they're gonna
see those show up and the way they're gonna worry about those is cost and
time on our SQCT target that we looked at.
