Which aspect of requirements analysis deals with verifying if the solutions are effective?

The aspect of requirements analysis that deals with verifying if the solutions are effective is requirements verification. This process involves assessing whether the documented requirements accurately reflect stakeholder needs and whether the implemented solutions meet those requirements. It ensures that what has been developed aligns with the intended purpose, functionality, and objectives outlined during the requirements gathering phase.

Requirements verification typically includes activities like reviews, inspections, and testing to confirm that solutions function as expected and solve the problems they were intended to address. This is crucial in ensuring quality and minimizing risks related to project outcomes.

The other options pertain to different components of the requirements analysis process. Value assessment focuses on evaluating the benefits of a solution in relation to its costs, modeling requirements involves visualizing requirements for better understanding, and contextual analysis examines the environment and constraints affecting the requirements. While these activities are important, they do not specifically concentrate on verifying the effectiveness of the solutions in meeting the established requirements.
