What is the primary benefit of using a traceability matrix in requirements management?

The primary benefit of using a traceability matrix in requirements management is that it ensures requirements align with project objectives. A traceability matrix serves as a tool that links each requirement to its source, which typically includes business objectives, stakeholders’ needs, and project goals. By establishing these connections, teams can verify that every requirement is necessary and contributes to the overall mission of the project.

This alignment is crucial because it helps prevent scope creep and ensures that the development efforts focus on delivering value that meets the stakeholders' expectations. It also facilitates better tracking of requirements throughout the project lifecycle, allowing for easier assessment of changes, impacts, and contributions to the project's success.

While reducing documentation effort, simplifying user interface design, and enhancing coding standards may bring benefits in their respective areas, they are not the central purpose of a traceability matrix. The matrix's main function revolves around maintaining a clear and organized view of the relationship between requirements and the overarching goals, making choice B the most accurate answer in the context of requirements management.
