CAPM Business Analysis Frameworks Practice Question
A business analyst needs to document the relationships between requirements, design, and test cases. Which artifact is best for this purpose?
⚠ Common exam trap
CAPM often tests confusion between documents that capture requirements (BRD) and the matrix that traces them — candidates may pick BRD thinking it covers traceability, but only the RTM provides the mapping.

Why each option matters

Correct answer & explanation
✓
Requirements Traceability Matrix
A Requirements Traceability Matrix (RTM) is specifically designed to map requirements to design elements, test cases, and other artifacts, ensuring bidirectional traceability. It documents relationships and helps verify that all requirements are covered by tests and design. This directly matches the business analyst's need.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use Case Diagram
Why it's wrong here
A Use Case Diagram is useful for illustrating functional requirements and actor interactions, but it does not explicitly document the traceability from requirements to design and test cases. It shows relationships between actors and use cases, not the complete mapping needed for coverage and impact analysis.
- ✗
Work Breakdown Structure
Why it's wrong here
The Work Breakdown Structure decomposes project scope into deliverables and work packages; it holds no requirement-to-design-to-test traceability links. It is tempting because it is a familiar CAPM planning artifact listing all project components, and would be correct for defining and estimating the work needed to deliver scope.
- ✗
Business Requirements Document
Why it's wrong here
The Business Requirements Document captures and prioritises business needs and stakeholder requirements; it does not map those requirements forward to design elements and test cases. It is tempting because it is the central requirements artifact, and would be correct for documenting and gaining agreement on what the business needs.
- ✓
Requirements Traceability Matrix
Why this is correct
A Requirements Traceability Matrix (RTM) is a formal document (often a table) that links each requirement to its source, design specification, test case, and verification status, making it the ideal artifact for tracking relationships throughout the project lifecycle.
