What practice area ensures that the solution meets requirements and functions as intended in its environment?

The practice area that specifically ensures that a solution meets its requirements and functions as intended in its environment is Verification and Validation (VV). This practice focuses on confirming that the product or system fulfills the intended use and meets the specified requirements through systematic evaluation methods.

Verification involves checking whether the product complies with regulations, requirements, and specifications. Validation, on the other hand, assesses whether the product actually fulfills its intended purpose in the real-world operational environment. This dual approach is essential for ensuring quality and functionality before a solution is delivered or fully deployed.

While Requirements Development and Management (RDM) is crucial for defining and managing requirements, it does not evaluate whether those requirements have been successfully implemented or if the solution operates correctly in its intended context. Therefore, it complements but does not replace the critical roles of verification and validation in assessing assurance of performance and operational effectiveness.
