Project Management


3/23

Project Management?

Art and science of mobilizing and managing

people.

Materials, equipment and money to completethe assigned project work on time.

Within budgeted cost &

Specified technical performance standard.


4/23

Management of Large Projects

Planning- goal setting, project definition, teamorganization.

Scheduling- relating people, money, andsupplies to specific activities and activities to oneand other.

Controlling- monitoring resources, costs,quality, and budgets; revising plans and shiftingresources to meet time and cost demands.

What is a Work BreakdownStructure?

The WBS is a graphical display of theproject.

WBS is a hierarchical listing of the sub-

components of a project.


7/23

What is the purpose of the WBS?

The purpose of the WBS is to divide the totalproject into small pieces, sometimes called workpackages.

Dividing the project into work packagesmakes itpossible to prepare project schedules and cost

estimatesand to assign management and taskresponsibility

9/23

Why use a WBS?

Identifies the tasks, subtasks and units of worknecessary to complete the project

Identifies the relationships between tasks

Increases the probability that every requirement will

be accounted Organize areas of responsibility and authority

Used to estimate project cost and schedule

Can be used to track the costs of each element

Can be used to monitor progress by completion oftasks


10/23

How should the project be brokendown?

No magic formula!! Breakdown by:

Functional or technological disciplines design/manufacturing/marketing/sales/finance

Organizational structure

Vendor/subcontractor responsibilities

Physical location

Systems and subsystems Or any combination, but generally end-product or

hardware-oriented.!!


11/23

Other WBS breakdown points

May proceed top-down or any way that gets thejob done

Need not be symmetrical


12/23

WBS levels?

Typically 5 levels:

1 Main project

2 Sub-project

3 Task

4 Sub-task

5 Individual processes or actions

A WBS planning key!!

REMEMBER the rule that the people who must do the

work should participate in planning it.

Different levels may be done by different groups:

Top management may do the first level or two andpass it on down to the operating levels for furtheramplification.

Software can help.


15/23

Basic guidelines

work described in a higher level must be thesum of all the work in the next lower levels.

work that will be performed by different peopleshould be clearly differentiated.

WBS should be flexible enough to allow forchanges.


16/23

WBS Structure

The WBS has a hierarchical structure Most general units at the highest level

Most specific units at the lowest level

Use a tree structure to provide task

details Split each top level general unit into subunits (level 2)

Split each subunit into further subunits (level 3)

For most projects it is unlikely to need to split subunits

to below level 4 Each unit should have an identifier code representing

the hierarchical, tree structure.


17/23

WBS CONCEPT

Outline of the Work to be Performed

Provides a Framework for Defining the Workon the Project

Provides a Framework for Planning

Work Not in the WBS is Work Not inthe Project.


18/23

At what level do you stop?

Stop when you reach a point at which you canestimate required resources to the desired

degree of accuracy.

Or, when the work will take an amount of timeequal to the smallest units you want to

schedule days, weeks, months, etc.

WBS and Activities in P3


21/23

WBS Software: WBS Chart Pro.

Windows-based project

management

WBS Chart Pro can be

used with Microsoft Project

The interface is seamless

and bi-directional.

A WBS toolbar button

can be installed into

Microsoft Project

for easy transfer of data.


22/23

Summary

The Work Breakdown Structure (WBS) helps youidentify and specify all the tasks associated with theproject.

A good WBS is based upon

A well defined scope for the project A set of system requirements

A good understanding of the project priorities

The WBS may need to be refined and updated for

each project phase A complete and well organized WBS will help assure

good schedule and cost estimates
