Which of the following statements accurately describes verification?

Verification is a critical process in systems engineering that involves assessing whether the requirements defined for a system have been fulfilled. It ensures that the system or components meet their specified requirements through various methods such as inspections, testing, and analysis. The essence of verification lies in confirming that the product is built correctly according to the specifications laid out at the beginning of the development process.

This process is distinct from validation, which checks whether the right product is being built in accordance with user needs and expectations. While user acceptance is important, it is part of validation and not the verification process itself. Similarly, confirmation of system usability or performance assessments are generally aspects of validation and evaluation rather than verification. Hence, the focus for verification remains strictly on adherence to the original requirements without delving into user experience or performance metrics.
