A customer is concerned about product quality as the production deployment approaches. What should the project manager do next to help ensure deliverable acceptance?

The correct answer is to evaluate the quality checklist to confirm product compliance. A quality checklist is a tool used to verify that all required quality standards and specifications have been met. By reviewing this checklist, the project manager can directly address the customer's concern about product quality and provide evidence of compliance, which is crucial for deliverable acceptance. Reviewing the approved product exit criteria is important, but the quality checklist provides a more granular, actionable step to confirm quality specifically. Testing product integration against requirements is a valid quality control activity, but the checklist is a broader verification tool that encompasses all quality aspects. Verifying the production budget before promoting the product is a financial control, not a direct action to address product quality concerns.
