Explanation
According to the Project Management Professional (PMP) Reference Materials, the first thing that the project manager should do when a project deliverable requires corrective actions to meet the project quality requirements is to update the issue log, identify the involved stakeholders, and assign resources to the corrective actions. This is because the issue log is a tool that records and tracks any issues that arise during the project, such as quality deviations, and how they are resolved. By updating the issue log, the project manager can document the problem, its impact, and the actions taken to address it. The project manager can also use the issue log to communicate the issue to the relevant stakeholders, such as the project sponsor, the customer, the team members, and the quality assurance personnel, and obtain their feedback and approval. The project manager can also assign the appropriate resources, such as staff, equipment, or budget, to implement the corrective actions and ensure that the project deliverable meets the quality requirements. Updating the issue log, identifying the involved stakeholders, and assigning resources to the corrective actions can help the project manager to manage the quality deviation in a timely and effective manner, and prevent further delays or defects in the project.
