According to the PMBOK Guide, the quality management plan is a component of the project management plan that describes how the project quality will be planned, assured, controlled, and managed. It also includes the quality standards, quality metrics, quality tools, quality roles and responsibilities, and quality audits.
In this scenario, the project manager should review the quality management plan to understand the requirements and expectations for the regulatory labels, the process and criteria for inspecting and verifying them, the actions and responsibilities for resolving any nonconformities, and the documentation and reporting of the quality results.
The other options are not appropriate because:
Conducting an expert judgment evaluation (option A) is not a suitable response to the issue. Expert judgment is a technique that involves consulting subject matter experts to provide information or guidance on a specific topic. While expert judgment can be useful in many situations, it is not a substitute for following the established quality management plan and procedures.
Updating the lessons learned register (option C) is not a priority at this stage. The lessons learned register is a project document that captures the knowledge gained from the project activities, including the positive and negative experiences, the best practices, and the recommendations for improvement. While updating the lessons learned register is an important part of the project closure, it is not a relevant action to address the current quality issue.
Reviewing the risk management plan (option D) is also not a relevant action to address the current quality issue. The risk management plan is a component of the project management plan that describes how the project risks will be identified, analyzed, prioritized, responded to, monitored, and controlled. It also includes the risk categories, risk appetite, risk thresholds, risk roles and responsibilities, and risk reporting. While reviewing the risk management plan can help the project manager to identify and manage any potential or actual risks related to the quality issue, it is not a direct or immediate response to the issue.
