PRINCE2F PRINCE2 Practices Practice Question
In the product-based planning approach, what is the purpose of the Product Breakdown Structure (PBS)?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To identify all the products needed for the project
The PBS is a hierarchical decomposition of all products to be created. It helps identify all deliverables. The Product Flow Diagram shows dependencies, and Product Descriptions define quality criteria. The Project Plan is not a direct output of the PBS.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To define the quality criteria for each product
Why it's wrong here
Quality criteria are defined in the Product Description.
- ✗
To show the order in which products will be created
Why it's wrong here
The Product Breakdown Structure (PBS) defines the hierarchy of all products required by the project, but it does not sequence their creation; that temporal ordering is the purpose of the Product Flow Diagram (PFD). This option is tempting because a breakdown structure often implies a logical sequence to practitioners, yet the PBS only decomposes scope, not the chronological steps of product delivery.
- ✗
To provide the cost estimate for each product
Why it's wrong here
Cost estimates are part of the Project Plan, not the PBS.
- ✓
To identify all the products needed for the project
Why this is correct
The PBS provides a complete list of all deliverables in a hierarchical structure.
