Explanation
According to the PMBOK Guide, the project manager should manage the project resources, including the human resources, in an effective and efficient manner. The project manager shouldalso coordinate and collaborate with other project managers and stakeholders to ensure the alignment and integration of the project activities and objectives. In this scenario, the project manager faces a resource issue that may affect the performance and delivery of both projects. The best course of action is to talk with project B's leader to discuss the possible impacts to both projects, and to find a mutually agreeable solution that balances the needs and expectations of both projects. This option demonstrates proactive and respectful project communication and resource management. Ensuring project A's team member can finish the work committed to project (option A) may not be sufficient or realistic, as it may ignore or overlook the needs and expectations of project B, and may create a conflict or resentment between the projects. Allowing project B's leader to continue building relationships (option C) may also be ineffective or inappropriate, as it may not address the root cause of the issue or provide a clear guidance on how to manage the resource allocation and utilization. Telling project A's team member to ignore project B's leader (option D) may also be counterproductive or unethical, as it may damage the relationship and trust between the projects, and may violate the professional responsibility and code of conduct of the project manager.
