Work Breakdown StructureWork Breakdown StructureFormal Definition per the PMBOK® Guide:
A Deliverable - Oriented Grouping of Project Elements that Organizes and Defines the Total Scope of the Project.Each Descending Level Represents an Increasingly Detailed Definition of the Project Work.
Work not in the WBS is outside the scope of the project.

The Work Breakdown Structure (WBS)The Work Breakdown Structure (WBS)
Used as a basis for a number of processes in particular to produce the subsidiary plans of the Project Management Plan.
The WBS is a deliverable-oriented hierarchy of decomposed project components that organises and defines the total scope of the project. The WBS is a representation of the detailed project scope statement that specifies the work to be accomplished by the project.
The elements comprising the WBS assist the stakeholders in viewing the end product of the project.
The work at the lowest-level WBS component is estimated, scheduled, and tracked.

The Dictionary of the WBSThe Dictionary of the WBS
A WBS dictionary is a companion document to the WBS that describes each WBS element. For each WBS element, the WBS dictionary includes a statement of work, a list of associated activities, and a list of milestones.
Other information can include the responsible organisation, start and end dates, resources required, an estimate of cost, charge number, contract information, quality requirements, and technical references.
WBS elements should be cross-referenced as appropriate.

100 % Rule100 % Rule
The next level decomposition of a WBS element (child level) must represent 100% of the work applicable to the next higher (parent) element.
But avoid excess bureaucracy!

If you follow the 100% rule, and define the WBS elements as nouns, you have won the battle to get an effective WBS.
