PK0-005 Project Life Cycle Practice Question
During project planning, the project manager decomposes the project scope into smaller, more manageable components. What is the resulting document called?
⚠ Common exam trap
PK0-005 often tests the confusion between scope-related documents, so candidates must distinguish the WBS (decomposition) from the scope statement (narrative description) and the charter (authorization).

Correct answer & explanation
✓
Work breakdown structure (WBS)
The Work Breakdown Structure (WBS) is the deliverable-oriented hierarchical decomposition of the total scope of work required to complete the project. It breaks the project into smaller, more manageable components called work packages, which can be estimated, scheduled, and assigned.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Scope statement
Why it's wrong here
The scope statement documents the project's boundaries, deliverables and acceptance criteria; it is an input to decomposition, not the output of breaking scope into smaller components. It is tempting because both concern scope, and a scope statement would be correct when the required document defines what is in and out of the project.
- ✗
Project charter
Why it's wrong here
The project charter formally authorises the project and names the project manager; it precedes planning and contains no decomposed scope components. It is tempting because it is a foundational scope-related document, and a charter would be correct when the required output is formal project authorisation rather than a work breakdown structure.
- ✓
Work breakdown structure (WBS)
Why this is correct
Decomposing project scope into smaller, manageable components produces the work breakdown structure, a hierarchical deliverable-oriented decomposition of total scope. It forms the foundation for estimating, scheduling and control, directly satisfying the planning activity described in the stem.
- ✗
Network diagram
Why it's wrong here
A network diagram depicts activity sequencing and dependencies, not the hierarchical decomposition of scope into manageable components. It is tempting because both artefacts are produced during planning and both relate to project work, but a network diagram would be correct when the required output is the schedule's logical activity flow.
