Work Breakdown

Structure


Project Scope Management

• Includes the processes required to ensure

that the project includes all the work

required, and only the work required, to

complete the project successfully

– Collect Requirements

– Define Scope

– Create Work Breakdown Structure (WBS)

– Verify Scope

– Control Scope

Project Baseline


A deliverable-oriented grouping of project elements that organizes and defines the total work scope of the project. Each descending level represents an increasingly detailed definition of the project work.

PMBOK® Guide Definition

WBS Definition


The tool for breaking down a

project into its component parts

(work package).

It is the foundation of project

planning and one of the most

important techniques used in

project management.

Advantages of WBS


WBS Decomposition


WBS Organized by Product


WBS Organized by Phase


WBS must be broken down starting at the top

Work packages must add up to the summary task (100% Rule)

Each summary task and work package must be named an activity that produces a product (use SMART Technique)
