Bidirectional Traceability is best described as?

• A. The relationship between a source and something dependent in both directions
• B. A way to track the relationship in both directions between a source and a dependent
• C. A one-way link
• D. A random mapping

Answer: (B)

Bidirectional Traceability means being able to follow links in both directions between a source item (like a requirement) and the work products that depend on it (design, implementation, tests) and back again. This two-way navigation lets you see not only how a source drives downstream items but also which sources are affected by changes in a dependent item. In practice, you maintain links so you can perform impact analysis, verify coverage (each requirement has corresponding design and tests), and ensure nothing is overlooked during changes. The best choice describes this tracking in both directions between a source and a dependent, rather than a one-way link or a random mapping.
