A customer is reporting that the projects deliverables are not meeting the acceptance criteria. Which of the following documents MOST likely needs to be updated?

A deliverable summary provides a high-level overview of deliverables but does not detail the specific quality requirements or acceptance criteria.

A quality checklist outlines specific criteria, steps, or items that must be checked to ensure the quality of a deliverable and confirm it meets acceptance criteria. If deliverables are not meeting these criteria, reviewing and updating the quality checklist is essential to correct the discrepancies and ensure future outputs are acceptable, reflecting revised standards or improved verification processes.

The risk register tracks potential future risks and their mitigation plans, not current issues with the quality or acceptance of completed deliverables.

A resource assignment matrix defines roles and responsibilities for team members, not the quality standards or acceptance criteria for project deliverables.
