What is primarily concerned with ensuring the correct implementation of system requirements?

The focus of verification is on ensuring that the system meets the specified requirements correctly. It involves systematically checking and testing the system to confirm that it has been built according to the documented specifications and that every requirement has been correctly implemented.

In the context of systems engineering, verification activities include reviews, inspections, analyses, and tests to determine if the system behaves as expected according to its requirements. This process provides evidence that the system is functioning as intended and that all functional, performance, and interface requirements are fulfilled. Verification helps to avoid defects and ensures compliance with the requirements before proceeding to later stages of the system lifecycle.

In contrast, other activities, such as validation, involve checking that the correct product has been built—specifically, whether the system meets the needs of the stakeholders and the intended use. Implementation refers to the actual process of building the system, while integration relates to combining different system components. Hence, verification stands out as the process explicitly aimed at confirming that system requirements have been correctly implemented.
