Which of the following represents a verification enabling system requirement?

The correct choice is a final Requirements Verification Traceability Matrix (RVTM), which plays a specific role in the verification process. The RVTM is a crucial tool in systems engineering that establishes the relationship between requirements and their corresponding verification methods. It maps requirements to tests, inspections, analysis, or demonstrations that will be used to verify that each requirement has been satisfied.

This traceability ensures that every requirement has an associated verification method, making it easier for engineers to demonstrate compliance during the verification phase. Having a well-documented RVTM allows for a systematic approach to verification, thus enabling a stronger connection between what is needed (the requirements) and how those needs will be confirmed as met in the final system.

The other alternatives, while important in the systems engineering process, do not specifically focus on verification enabling. For instance, a functional specification details the functions that a system must perform, but it does not directly enable verification processes. Similarly, a design constraints document outlines limitations within which a system must operate, and a user requirement statement captures what the users need from the system, but neither focuses on the methods by which these requirements will be verified.
