Which statement correctly defines a verified requirement?

A verified requirement is one that has been thoroughly reviewed and confirmed to be accurate, complete, and aligned with the established standards of quality for requirements. This means that it is not only well-defined but also meets the criteria needed for clarity, consistency, and feasibility. Verification ensures that the requirements can be understood by all stakeholders and can be traced back to the needs of the business or project objectives.

Well-defined requirements provide a solid foundation for the development process and facilitate clearer communication among team members, reducing the risk of misunderstandings or errors later in the project. This stage is crucial in the requirements lifecycle, as it ensures that all requirements will lead to actionable tasks during implementation.

The other options do not align with the definition of a verified requirement. A requirement that has been successfully implemented reflects an outcome of the development process rather than its verification. A requirement in draft form indicates that it hasn’t undergone the rigorous checks necessary for verification. Similarly, a requirement that has not been approved is still awaiting confirmation and cannot yet be considered verified. Thus, being well-defined and adhering to standards is what constitutes a verified requirement.
