Requirements Traceability is a process used in project management and software development to ensure that all requirements are tracked throughout the project lifecycle. It involves linking requirements to their origins, such as stakeholder requests or business needs, and tracking their implementation in the final product. This helps teams verify that all requirements are addressed and fulfilled. By maintaining a clear traceability matrix, teams can easily identify which requirements have been met and which are still pending. This practice enhances communication among team members, reduces the risk of scope creep, and ensures that the final product aligns with initial expectations and quality standards.
