What process confirms that specified requirements have been fulfilled through thorough examination?

The correct answer is verification because it specifically focuses on the process of evaluating work products to determine whether they meet the requirements and specifications set forth at the beginning of a project. Verification involves checking that the product conforms to the requirements and that the development processes are applied correctly. It is typically a formal evaluation process that includes inspections, reviews, and analysis.

In this context, verification ensures that each specified requirement is tracked and checked against the actual work output, confirming that the product has been built correctly according to the established criteria. This process is crucial in software development, as it helps identify issues early and ensures that the product's development aligns with the initial requirements, thereby reducing risks and improving quality.

While options like validation, testing, and review are all important processes in software quality assurance, they serve different purposes. Validation focuses on ensuring that the right product is being built according to user needs and requirements, while testing involves executing the software to identify defects. Reviews often provide a less formal examination of work products to catch discrepancies before they progress further. However, none of these processes are dedicated solely to confirming fulfillment of specified requirements in the way that verification does.
