Duration of task

[Wesley Willis]

Hello,

I hope someone can help me with the following problem.

* When I assign one resource (A) with a normal (40 hour) calender to a task
of 60 hours it will take 7,5 day's to finish it.
* When I assign one resource (B) with a 20hour calender to a task of 60
hours it will take 15 day's to finish it.

So far so good, but when I assign both resources to the task it still takes
7,5 day's to finish it, because project divides the work between the two
resources (both 30 hours of work).

But I want project to schedule the task (automatically) in a way that task
finishes in 5 day's. That is possible when project assigns 40 hours of work
to resoure A and 20 hours to resource B.

Wesley

PS I know that I can adjust hours in the Resource Usage screen, but I want
Project to do it by default.

 

[Rob Schneider]

Wesley,

First question ... are you using a task type "Fixed Duration", "Fixed
Units", or "Fixed Work"? From there can you work it out?

This is where I'd split the screen in the Gantt chart to make the
assignments. Select the task. In the bottom window click in the resource
column and add the full-time resource, 100%, 40 hours work. In the next
line add the part-time resource, 100%, 20 hours work. Now click the "OK"
button.

Or if you prefer to use the regular Assign Resources dialog, remember that
100% for your 4 hour a day resource is 4 hours per day. Enter the task in
the task list with a 5 days duration. Open the Assign Resource, select Joe
Fulltimer, hold down control and select Betty Partimer, and click the
"Assign" button. Make sure you assign them both at once, not consecutively.
It should leave the duration at 5 days, assign both resources @ 100%, with
one doing 40 hours work and the other at 20 hours work.

The inital task duration should be 5 days or 40 hours, BTW, not 60. Don't
mix up duration estimates with work estimates when you initially enter the
task and its expected duration in the Gantt chart task list.

Hi Wesley,

Project doesn't do it that way, that is why people tell you how you can do
it, I'm afraid.

Thanks for you're suggestions, but they did nog solve my problem, when I
assign two resources at once it still divides 60 hours equaly (30/30) among
the two resources and finishes in 5,5 day's.

I will try to be more specific/clear.

The only thing a know is that I have 60 hours for a task (fixed price). Then
I assign two resources with different calenders (on 40 hours and one 20
hours a week) to this task and I want Project to finish the task As Soon As
Possible. So Project should calculate/see that it can finish in 5 day's. I
don't want to set the duration myself or assign a specific amount of hours
to a resource, because that's impossible if you have more difficult
calenders, hours to spend and resources on one task.

I hope I'm clear about what I want, but I also added an attachment with some
additional information/visualisation.

[Steve House [MVP]]

Try the split screen method that I suggested, assigning the first resource
to do 40 hours at 100% and the second to do 20 hours @ 100%, it will work
and I checked it just now to make sure. You're right on the resource
assignment toolbar button, it does still split it 30/30 - should have double
checked it before typing - sorry, my bad.

Just remember to set the task's duration to 40 hours, NOT 60 hours, when you
enter it. The starting duration is the time required to do the work, not
the total amount of the work. Since you're estimating 60 hours already as
you start the process, it's no big deal to prorate it yourself between the
two resources according the way you'd like them to do it.

But the duration is what I want Project to calculate, vacantion and days of
are after all set in the individual calenders of a resource. I only enter
Work (60 hours) and add resources.

It is a bit stupid that when I add more resources to a task and those

later. Don't you think?
Or am I missing some of the core concepts of Project?

Hi Wesley,

Core concepts, well maybe.
Nedarly all of the time, Project considers multiple resoruces on a task same
as multiple tasks each with one resource.
Pity it is! but we have to live ith it.

[Wesley Willis]

Well there is one positive side.
Almost everything in a real project takes longer than you expect to really
finish it, so Microsoft Project still makes de best estimation of duration
.

Thanks for the answers. I will be back with others questions, and try to
answer some questions of others.

Thanks for you're suggestions, but they did nog solve my problem, when
I assign two resources at once it still divides 60 hours equaly (30/30)
among the two resources and finishes in 5,5 day's.

I will try to be more specific/clear.

The only thing a know is that I have 60 hours for a task (fixed price).
Then I assign two resources with different calenders (on 40 hours
and
one 20 hours a week) to this task and I want Project to finish the task
As Soon As Possible. So Project should calculate/see that it can finish
in 5 day's. I don't want to set the duration myself or assign a
specific amount of hours to a resource, because that's impossible if
you have more difficult calenders, hours to spend and resources on one
task.

I hope I'm clear about what I want, but I also added an attachment with
some additional information/visualisation.

message This is where I'd split the screen in the Gantt chart to make the
assignments. Select the task. In the bottom window click in the
resource
column and add the full-time resource, 100%, 40 hours work. In the
next
line add the part-time resource, 100%, 20 hours work. Now click
the
"OK"
button.

Or if you prefer to use the regular Assign Resources dialog, remember
that
100% for your 4 hour a day resource is 4 hours per day. Enter the
task in
the task list with a 5 days duration. Open the Assign Resource,
select Joe
Fulltimer, hold down control and select Betty Partimer, and click the
"Assign" button. Make sure you assign them both at once, not
consecutively.
It should leave the duration at 5 days, assign both resources @ 100%,
with
one doing 40 hours work and the other at 20 hours work.

The inital task duration should be 5 days or 40 hours, BTW, not 60.
Don't
mix up duration estimates with work estimates when you initially enter
the
task and its expected duration in the Gantt chart task list.

Hello,

I hope someone can help me with the following problem.

* When I assign one resource (A) with a normal (40 hour) calender to
a
task of 60 hours it will take 7,5 day's to finish it.
* When I assign one resource (B) with a 20hour calender to a task of
60
hours it will take 15 day's to finish it.

So far so good, but when I assign both resources to the task it still
takes 7,5 day's to finish it, because project divides the work
between the
two resources (both 30 hours of work).

But I want project to schedule the task (automatically) in a way that
task
finishes in 5 day's. That is possible when project assigns 40
hours
of
work to resoure A and 20 hours to resource B.

Wesley

PS I know that I can adjust hours in the Resource Usage screen,
but I
want
Project to do it by default.

If a task requires 40 hours of work, a resource working 8 hours a week
will requite 5 times as many weeks as a resource who works 40 hours a
week. That 40 hour task will require 5 weeks for someone working 5
hours a week, 1 week for someone who works 40 hours a week, and 1 DAY
for 5 people who each work 40 hours per week (ie, 8 hours per day) who
are working togther.

Your 60 man-hours is the total energy put out by however many resources
you put on the task, If you don't want them to share the work equally,
you have to tell project how to divide it up. The duration is the
amount of time it requires to finish the task from the time the earliest
starting resource begins work until the latest finishing resource is
done with his share. Unless you manually override, project will assume
all your resources start together and each of them drops away when they
finish their share of the work. So unless you override, project assumes
the 60 hours is divided evenly between the two resourcs, 30 each. The
40 hour resource works until his 30 hours is done and the 20 hour
resource works until HIS 30 hours is done. Since he's the one that
takes the longest, the tasks duration is from the time they start until
the 20 hours a week guy finishes 30 man-hours of work. Anything else
requires you to take control of the details of the process.

But the duration is what I want Project to calculate, vacantion and days of
are after all set in the individual calenders of a resource. I only enter
Work (60 hours) and add resources.

It is a bit stupid that when I add more resources to a task and those
resources just work 8 hours a week in stead of 40, that the task finishes
later. Don't you think?
Or am I missing some of the core concepts of Project?

Wesley

Just remember to set the task's duration to 40 hours, NOT 60 hours, when
you enter it. The starting duration is the time required to do the work,
not the total amount of the work. Since you're estimating 60 hours
already as you start the process, it's no big deal to prorate it yourself
between the two resources according the way you'd like them to do it.

Thanks for the quick answers.
I can know tell my co-workers that it can't be done automatically and
that it is not my lack of knowledge ;-).

I will advise my co-workers two work with the split screen option to make
manual adjustments.

Wesley


Try the split screen method that I suggested, assigning the first
resource to do 40 hours at 100% and the second to do 20 hours @ 100%, it
will work and I checked it just now to make sure. You're right on the
resource assignment toolbar button, it does still split it 30/30 -
should have double checked it before typing - sorry, my bad.
