In Requirements Development and Management, what is the critical aspect of tracing requirements?

Bi-directional traceability is essential in Requirements Development and Management because it allows for comprehensive tracking of requirements throughout the entire lifecycle of a project. This involves establishing and maintaining links between the requirements and the associated design, implementation, testing, and verification artifacts.

By tracing requirements in both directions—forward from requirements to corresponding designs and implementations, and backward from products to the original requirements—stakeholders can ensure that all requirements are met and that any changes or modifications to the requirements are appropriately managed. This dual approach helps in assessing the impact of changes, ensuring completeness, and validating that all requirements are fulfilled by the final product.

Incorporating bi-directional traceability also lends itself to better communication among team members, as it clearly illustrates how each requirement contributes to the end product, enabling better decision-making throughout the project.
