PRINCE2F PRINCE2 Practices Practice Question
In product-based planning, what is the purpose of a Product Flow Diagram?
⚠ Common exam trap
In PRINCE2, the trap here is that candidates often confuse the Product Flow Diagram with the Product Breakdown Structure (PBS), mistakenly thinking the PFD shows a hierarchy rather than a sequence and dependencies.

Correct answer & explanation
✓
To show the sequence of product development and dependencies
In PRINCE2's product-based planning, the Product Flow Diagram (PFD) shows the sequence in which products are developed and the dependencies between them. This helps in planning the order of activities and identifying where products are needed as inputs for others. Option B is correct because the PFD's primary purpose is to map the logical flow and dependencies, not to define quality criteria, show hierarchy, or estimate effort.
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 documented in each product description, not the Product Flow Diagram. The diagram shows the order in which products are produced and their dependencies, so it is tempting because it does display every product, yet it carries no quality information — that content sits in the product descriptions within the Product Breakdown Structure.
- ✓
To show the sequence of product development and dependencies
Why this is correct
Product Flow Diagrams map each product to its creator and the products it depends on, establishing the sequence in which products must be developed. This dependency-driven sequencing is the diagram's defining purpose, distinguishing it from the Work Breakdown Structure's hierarchical decomposition.
- ✗
To show the hierarchical breakdown of products
Why it's wrong here
A Product Flow Diagram maps the sequence and dependencies in which products are produced, not their hierarchical decomposition; that hierarchy belongs to the Product Breakdown Structure. It is tempting because both are product-based planning techniques, yet the flow diagram shows order and links between products, not parent-child levels.
- ✗
To estimate the effort required to create each product
Why it's wrong here
Effort estimation belongs to the activity of estimating, drawing on the Product Breakdown Structure and product descriptions, not the Product Flow Diagram. The diagram's purpose is to show the sequence and dependencies between products, so it is tempting because it does map products, but it captures ordering rather than resource or effort data.
