What does it mean when a requirement is deemed "traceable"?

When a requirement is deemed "traceable," it signifies that it is clearly defined and can be linked to other requirements or project objectives. Traceability is a critical aspect in requirements management as it ensures that each requirement can be tracked throughout the project lifecycle. This means that stakeholders can see its origin, how it relates to other requirements, and its importance in achieving the overall project goals.

For instance, traceability allows teams to understand the relationships between high-level project objectives, specific functionalities, and various requirements, helping to manage scope and track changes effectively. This interconnectedness is essential for ensuring alignment between what is being built and what is needed, thus minimizing risks of overlooking essential aspects during development and ensuring all requirements are validated and tested.

In contrast, the other options do not encapsulate the essence of traceability. Requirements that can be ignored do not contribute to the project and hence do not require traceability; those focusing solely on technical aspects may lack the broader context needed for traceability linking. Lastly, a requirement that cannot change contradicts the dynamic nature of project requirements, where adaptability is often needed based on stakeholder feedback and evolving project conditions.
