Bidirectional Traceability is?

Bidirectional Traceability is?

• A. A one-way link from a source to its outputs
• B. A method to trace only the primary source
• C. A way to track the relationship both to and from a source and something dependent on that source
• D. A process to reverse trace results

Answer: (C)

Bidirectional traceability means you can follow a relationship both forward and backward between a source artifact and what depends on it. This lets you see, for any requirement or source item, which design elements or outputs implement or use it (forward tracing) and, conversely, when you look at a design element or output, identify exactly which requirements or sources it relates back to (backward tracing). This dual capability supports verifying coverage—ensuring every requirement is realized by the right design components—and enables impact analysis if something changes. Why this is the best fit: it explicitly describes tracking the relationship to and from a source and something dependent on that source, which is precisely what bidirectional traceability encompasses. One-way links only cover forward tracing, and options that mention only the primary source or reverse tracing results miss the full, two-way linkage that helps maintain consistency and traceability across the project.
