Why is it Needed ?﴾ Simplifying the project execution﴾ Accurate and readable project organization.﴾ Accurate assignment of responsibilities to

the project team.﴾ Indicates the project milestones and control

points.﴾ Helps to estimate the cost, time, and risk.﴾ Illustrate the project scope, so the

Tips for Constructing WBS

﴾ WBS should be viewed as a roadmap.﴾ It should be descriptive, not vague.﴾ It should list out all the steps down to

the smallest level.» Ex: If 5 steps are there then all should

be listed.

﴾ Assuming that “everyone knows what steps are required to complete the task” means failure.

Facts for Constructing WBS₪  Elements of each WBS Element:

€ The scope of the project, "deliverables" of the project.

€ Start and end time of the scope of project.€ Budget for the scope of the project.€ Name of the person related to the scope of project.

₪ No hard and fast rule.

€ Some rules for determining the smallest chunk:» Thumb Rule» If it makes sense Rule,» 80 hour rule,» Three week/year rule, etc.

3 Week Rule : Steps - 1STEP - 1₪List all major deliverables and the

high-level tasks specifically mentioned or gleaned from the scope description.

₪Side note should delineate ↔What is to be considered.↔What is out of scope, i.e. not to be

considered.

3 Week Rule : Steps - 2STEP - 2₪Select a deliverable.

€ Name all of the tasks required

₪Heading(known as Summary Task) - complete descriptive sentence.

₪Side note should delineate € What is to be considered.€ What is out of scope, i.e. not to be considered.

3 Week Rule : Steps - 3STEP - 3• Break down each task – For another project manager to fully follow the

process.• Provides – The basis for budget estimating – A checklist for monitoring and controlling.

3 Week Rule : Steps - 4STEP - 4₪ Rearrange the tasks and work packages

£ For logical flow -> To perform the summary task.₪ Rearrange the summary tasks

£ For Logical flow -> To perform the project. ₪ Ensure

£ Task headings are meaningful £ There is a balance between having enough tasks

and work packages to provide enough detail without overkill.

WBS Dictionary₪Set of specific definitions

€Thoroughly describe the scope of each work element identified in the WBS

₪Components.€A work element dictionary

sheet» Provides the title of the

work element, » The project contractor

WBS and » The contractor’s

accounting codes, the budget and reporting number, and

» A detailed description of the work to be performed by this element, including deliverables

€A tabular summary of the dictionary elements cross-referenced

» WBS indenture level, » The WBS revision, the

element title,» The project contractor

WBS code, and » The contractor’s

accounting code (if desired).

Misconceptions£ A WBS is not an exhaustive list of work.

» Comprehensive classification of project scope.

£ A WBS is » neither a project plan, » a schedule, » nor a chronological listing. » Specifies what will be done, not how or when.

£ A WBS is not an organizational hierarchy, » It may be used when assigning responsibilities

Key Points﴾ Work breakdown structures are great for developing and validating the scope of a project.

﴾ Work breakdown structures are most powerful when shown in a graphic style, similar to an organization chart.  They can also take on the form of a simple outline.

﴾ Work breakdown structures allow people from various backgrounds, disciplines, and perspectives to understand the activities being planned.
