When undertaking requirements verification, the stakeholders who will be using the requirements are best positioned to determine if they are of good quality. These stakeholders have the practical experience and understanding of their needs and the context in which the requirements will be used. Their feedback ensures that the requirements are relevant, complete, and feasible. Involving stakeholders in the verification process helps in aligning the requirements with actual business needs and ensures that the final solution will be effective and satisfactory.
