How to Get Resource Loading Histogram/S Curve

in Primavera P6

The resource histogram allows us to use projected and historical actualized data to trend resource quantities, resource hours and

cost in future. It also allows us to determine the potential risks of excessive supply of resources or lack of resourcerequirement.

This tutorial demonstrates how resources allocation chart (histogram/S curve) is produced in Primavera P6. Assume that you havedone Assigned activities and Sequenced activities to see resource loading histogram/S curve bar chart in Primavera P6. After

assigning and sequencing of activities,

(1) Allocate overall resource and their rated cost

(2) Assign resources in activity detail section and

(3) View resource loading histogram/S curve.

1) How to allocate overall resources and cost?

a) Go to Enterprise> Resource>

Note: When you are at Resource, you will see the filter name Current Project Resources If you have already opened a resourceloaded project. See figure below

A blank project resource dictionary only will be displayed if no resource has been added to current project.

See below image.

b)Add New Resource (Note : If the existing resources are not applicable for a specific project or no resource has been assigned to

current project.You can skip this step if the required resources are available in resource dictionary.)

When you try to add new resource, you will get the message like In order to add resource, the filter will be changed to display al

resources

and you will see all resources for all the projects. New Resource Wizardwill be prompted, and follow the wizard. You wil

be asked to enter the following,

Resource ID,

Resource Name,

Allocate Resource Type (Labor, Non labor and material),

Rate (Price/Unit), Default Units/Time and Max Units/Time,

Contact address if applicable

Resource roles which describes their skills

Resource Calendar

Select Auto- compute if youwant actual units are updated by

Primavera or select Do not auto-

compute actual if you can update

manually for actual man hours spent.

Timesheets set up and log in

After entering of all data, you will

notice that the newly added resources

are not in the desired location.

Therefore, allocate those resources

according to their resource level. For

example, Pipe fitter, Rigger/Signaler,

General worker, Fire watches man,Workshop labor, Painter, etc are

allocated under construction

department of Petrochemical Projects.

See figure below.

b) You can customize the

appearance of bar chart by

the Resource Usage

ProfileOptions. Right

Clickon the bar chart area to

find Resource Usage Profile

Options

. You can select Bydate to see interval data

(Histogram Chart) and select

Cumulative (S Curve) to see

total manpower unit in the

following check box below.

c) The following check box is

used when you want to show

manpower resource profile

instead of man hour unit. P6

will calculate total men perperiod (interval) based on

working hrs per period

(interval) and total man

hours per period. For

example, total men per week

would be 10 when total man

hours for a week are 400 and

40 working hrs per week.

d) And then, select all resources in resource column to view overall man power allocation. To print the bar chart, Go to print preview >

page set up > Options > Select Profile and unselect Activity Table, All columns, Grid lines and Gantt chart. Set the time s cale start

from PS-Earliest Project Start to PF-Latest Project Finish. Finally you will see the bar chart as below.

e)According to above bar chart, the

weekly interval manpower is shown on

the left side and total manpower

allocation is on the right side.

f) One of the reason for viewing

resource histogram is to identify

overallocated resources against the

available resources. To view any

overallocated resources in your project,

go to Data tag on "Resource Usage

Profile Options" window, then

select Show Limit and Show

Overallocation. Any resource unit above

the limit line (black line) is over

allocated. Normally, overallocated

resource is shown in red bar

How to view Stacked Histogram?

You can also see Stacked Histogram for this manpower allocation.Right Clickon the bar chart area to find Stacked

Histogram.Firstly, click on "Stacked Histogram" tag, and then you can go to "Resource Usage Profile Options" to get screen shot in

step-g. See figure below.
https://lh6.googleusercontent.com/-j7p7IYazCXg/TX4abswFEeI/AAAAAAAAAMM/Mt_v1mzNGvU/s1600/Stacked+Histogram+for+P6.jpghttp://3.bp.blogspot.com/-2-Uhk2vx9XI/Ua1iVAJd3uI/AAAAAAAAAbg/lpB993wUnUg/s1600/Over+allocated+resource+in+P6.jpg


7/7

Go to Resource Profile options > Assign Resource Filter/Group Name > Select Total cumulative curve as shown in Figure below.

Finally, you will get Stacked Histogram as shown in below. The stacked histogram represents the manpower allocation by individual

trade/discipline for a particular

period as well as total manpower

allocation (total manpower = 200

men, see the following figure) for all

time . It can be printed the same way

done on item 3, d.

When Stacked histogram is viewed,

one thing to take note is

"Overallocated Resource" can't beidentified on that view. Switch back

to normal histogram by deselecting

"Stacked Histogram" so as to analyse

overallocated resources.
