Who is responsible for verifying that a solution meets the business requirements?

The responsibility for verifying that a solution meets the business requirements primarily falls on the role of the tester. Testers are tasked with developing test cases and executing tests against the implemented solution to confirm that it behaves as expected and fulfills the defined requirements. They conduct various types of testing, including functional, regression, and user acceptance testing, ensuring that the system delivers the desired capabilities and meets the quality standards set forth by the business.

This verification process is critical as it involves checking the solution against the stated business requirements, it helps in identifying any discrepancies, defects, or issues before the solution is deployed to the end-users. Testers act as an important line of defense in ensuring that the solution functions as intended and that the stakeholders' needs are met effectively.

While other roles, such as business analysts, stakeholders, and project managers, play key parts in defining requirements and overseeing project execution, the actual validation against those requirements is within the specialized skill set of the testing team.
