What is the primary purpose of Requirements Traceability?

• A. To ensure that all requirements are covered by at least one function and all functions are justified by a valid requirement.
• B. To track budget and expenses
• C. To document change requests
• D. To monitor schedule performance

Answer: (A)

Requirements Traceability involves mapping each requirement to its implementing function and to the tests that verify it. The primary purpose is to ensure that every requirement is covered by at least one function and that every function is justified by a valid requirement, creating a complete, auditable chain from need to solution. This makes it possible to verify that nothing essential is missing and that nothing extraneous is added, while also enabling impact analysis if requirements change and ensuring proper test coverage. It’s not primarily about tracking budget, documenting change requests, or monitoring schedule—those are separate project-management activities.
