When a critical ERP system upgrade encounters a validation issue and is at risk of exceeding the allotted downtime, the project manager should begin executing the rollback plan. This action is taken to ensure that the system can be restored to its previous state without exceeding the downtime limit, thus minimizing the impact on the business operations.

If a project manager continues to receive project-related work after the project has been released into production, it suggests that the project closure phase was not completed properly. The project closure phase involves several activities, including ensuring that all project deliverables are accepted, documenting the lessons learned, releasing project resources, and formally closing the project. If these activities are not completed, the project can remain ‘open’ in a sense, leading to continued work and inquiries.

References = The answer is based on standard project management practices and the importance of the project closure phase as described in project management literature. For detailed information, please refer to the CompTIA Project+ Study Guide and other official CompTIA resources. Specific references to the closure phase can be found in the CompTIA Project+ PK0-005 Cert Guide1 and the CompTIA Project+ Certification Exam Objectives2.

An Ishikawa diagram is a tool that the project team should use to find the cause of the defects associated with project deliverables. An Ishikawa diagram, also known as a fishbone diagram or a cause-and-effect diagram, is a graphical tool that shows the possible causes of a problem or effect using a fishbone-like structure. An Ishikawa diagram can help to identify and analyze the root causes of defects or issues and find solutions to prevent or eliminate them.

A Finish-to-Start dependency implies that a subsequent activity cannot start until a previous one finishes. In this scenario, the manufacturing process (subsequent activity) cannot begin until the critical raw materials (previous activity) have been delivered. This type of dependency is the most common in project schedules and is likely being affected by the global shipping slowdown, causing delays in the start of the project's production run.
