Explanation
The project manager should use the issue log to update the details and communicate to relevant stakeholders about the supplier's inability to deliver the materials due to a large-scale labor problem. An issue log is a document that records and tracks any issues that arise during the project and require resolution. The issue log can help the project manager to identify, analyze, prioritize, assign, monitor, and close the issues. The issue log can also facilitate communication and transparency among the project team and stakeholders. The projectmanager should not use a change request, a project schedule, or a risk register, as these documents are not suitable for capturing and reporting the current issues that affect the project.
