A customer is concerned with the quality of the product delivery, as the production deployment is approaching. What should the project manager do next to ensure acceptance of the deliverables?

Verifying the production budget is a financial control and does not directly address the customer's concerns regarding the product's quality or fitness for acceptance.

An agile quality checklist defines specific criteria and standards that the product must meet for acceptance. Evaluating this checklist directly verifies that the product adheres to the agreed-upon quality requirements, thereby addressing customer concerns and ensuring deliverable acceptance.

Reviewing approved exit criteria primarily focuses on conditions for project closure rather than verifying the ongoing quality of the product's deliverables for customer acceptance.

While testing product integration is part of ensuring quality, evaluating the comprehensive quality checklist confirms compliance against all established quality metrics for final acceptance.
