Correct answer & explanation
✓
Requirements Traceability Matrix
The Requirements Traceability Matrix (RTM) is the best artifact for documenting relationships between requirements, design, and test cases because it provides a structured, cross-referenced mapping that ensures each requirement is linked to corresponding design elements and test cases, enabling impact analysis, coverage validation, and change management. A Use Case Diagram describes system behavior and actor interactions but does not explicitly trace requirements to design and test cases; it is more focused on user goals and system functions. Other artifacts like the WBS (work breakdown structure) break down project deliverables, and the BRD captures high-level business needs, neither of which provide traceability across the development lifecycle.
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
A Work Breakdown Structure (WBS) decomposes project deliverables into smaller components for planning and scheduling; it does not map requirements to design or test cases.
- ✗
Business Requirements Document
Why it's wrong here
A Business Requirements Document (BRD) defines high-level business needs and objectives but lacks the detailed traceability links to design and test artifacts; it is a narrative rather than a cross-reference matrix.
- ✓
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.
