Who is primarily concerned with the requirements being correct?

The customer is primarily concerned with the requirements being correct because they are the ones who have the final say about the functionality and quality of the product being developed. Accurate requirements are critical to ensure that the final product meets the user's needs and expectations. The customer is focused on ensuring that the delivered product aligns with their vision and solves the problems they intend to address.

When the customer verifies that the requirements are correct, they can provide valuable feedback and adjustments that help shape the development process. This involvement is essential because the accuracy of requirements directly influences project success, customer satisfaction, and the overall quality of the deliverable.

While other roles such as testers, developers, and project managers play significant roles in the project, their focus is typically more aligned with implementation and execution of those requirements rather than confirming their correctness. Testers ensure that the requirements are satisfiable through testing, developers implement them according to specifications, and project managers oversee and facilitate the project's execution. However, the fundamental responsibility of verifying that the requirements are indeed correct lies with the customer.
