Hello again and welcome back to our call some project 2019 advanced in this section we're going to take
a look at the use of overtime.
And we have a particular problem here with Version 6 of the website's schedule in that the current end
date is right about the middle of January and we're really hoping to have all of this wrapped up by
the end of December.
So what we're looking at is some way of getting back some of the time that we seem to have lost here.
Now what we've identified is that potentially we could save some time on the testing task that I have
highlighted just here.
The testing begins in mid to late October and runs right through to the end of December.
And that involves 400 hours of work so that's 50 working days at eight hours a day.
And we have three different resources working on it.
Now none of these reasons are working on it full time but they do have other commitments on other projects.
So what we're looking at here is one option for winning back some time is to get those resources to
do overtime work on this task.
Now that's not the only option for clawing back some time but it is the one that we're going to look
at in this section.
Now one thing I'd like to cover first of all before we actually apply overtime here is to look at the
cost of testing because one of the unfortunate consequences of overtime is usually that it involves
an increase in cost.
So let's add another column and we're going to look at cost here and again against the testing task.
50 days 400 hours the total cost is twenty thousand five hundred dollars.
So let's now take a look at how we might use overtime here.
Now I'm going to jump up to the task tab and I'm going to click on the details button which you'll find
in the Properties Group.
And that will just display the details for the task that I currently have selected.
And you can see here it says I selected the task named testing and I can see in the table below all
of the resources currently assigned to that task.
The units and the work so you can see here that we have 100 hours assigned to northern Farm Foods 100
hours assigned to Deborah Ashby and 200 hours assigned to Bakersfield associates and those are in the
units zero point two five zero point two five and zero point five.
Now this is not quite the same as the baseline work that was originally established here but I'm going
to ignore baseline work at the moment and we're just going to deal with overtime.
Now the very simplest way to do this is to give everybody a proportionate amount of overtime work.
And one very important point to bear in mind when you allocate overtime work is that it isn't shown
in some special way on the schedule.
You don't even have to adjust any calendars to accommodate overtime work the way that it works is that
there is an agreement that overtime be done and then the resource or resources that need to do the overtime
just do it.
They do it within the duration of the task when they do do it how they do it what arrangements they
make are completely up to them although of course if they do have a specific overtime rate we will notice
the difference in the cost for the task.
So what I'm going to do here first is just try and say well let's give everybody a quarter of their
workers overtime.
So I'm going to give Northern Farm Foods twenty five hours.
Now it's important to realize that the overtime work figure is included in the work figure to its left.
So the 100 hours work on northern Farm Foods is still 100 hours work for northern Farm Foods but it
includes 25 hours being done as overtime.
So let's do the same for Deborah Ashby so we're going to again say 25 hours and Bakersfield associates
is going to be 50 hours unless click on.
Okay.
And I'm just going to get rid of that details pain.
Now notice the day to the end you can see that we've clawed back quite a bit of time.
If you remember previously that end date was in mid January and now we are back towards the end of December.
But as a consequence the cost has gone up from twenty thousand five hundred to twenty three thousand
one hundred and twenty five dollars.
So the use of overtime has achieved the schedule objective.
Our project is now finishing roughly at the end of December.
But there has been a monetary financial cost to that.
Now note a couple of other options there.
One option we might have had would be for example if one of the participants in the testing and said
Well I don't actually have the capacity to do in the overtime we might have redistributed the amount
of work.
Now I've kept the work at 400 hours.
The idea wasn't to cut down on how much work we did on testing just to get parts of it done as overtime
if I redistributed it.
So for example if Debra said I can do overtime and Bakersfield associates said no that's all the capacity
we've got we could maybe move 100 hours of Bakersfield to Deborah's and let Deborah do more overtime.
So with a combination of possible redistribution and the allocation of overtime according to the capacity
that resources have got to do over time you have one option for reducing the duration of a task.
Now although we're primarily here looking at issues related to cost and in this case how the use of
overtime is increased cost in order to shorten a task.
Another way you might deal with this specific problem might be for example to give the testing task
a task calendar.
So for instance a calendar that would allow work to be done at the weekend or maybe late in the evening
and then the provided resource calendars allow them to work at the weekend or late into the evening
then work on the task could be scheduled.
So for the moment we've achieved our objective of shortening the project time scale even though we've
had to spend a little bit more money to do that.
That's it for this section.
I will see you in the next one.
