• 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

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
The tool for breaking down a
project into its component parts
(work package).
It is the foundation of project
