Which term describes the verification that the design complies with performance requirements in the RFP?

The term that describes the verification that the design complies with performance requirements outlined in the Request for Proposals (RFP) is substantiation. Substantiation involves providing evidence or proof that a particular design or product meets the specified criteria and performs as intended. In the context of the RFP, substantiation serves to demonstrate that the design aligns with the project's performance goals, thus building confidence in the proposed solution.

This process typically includes technical analysis, documentation, or testing results that show the design's capabilities and compliance with the expected performance standards.

While validation refers to the process of checking if the right requirements are being met, and certification often involves formal recognition by a third party that a product or system meets certain standards, substantiation is specifically focused on the proof of performance relative to the RFP's requirements. Accreditation can be a broader process that establishes the credibility of an organization or system, but it does not directly pertain to the verification of compliance with design performance requirements in the same targeted way as substantiation does.
