The project manager should update and share the guideline document dealing with team communication to ensure that there are no potential misunderstandings among the virtual team members. This is because the guideline document defines the communication requirements, methods, channels, frequency, and protocols for the project team, especially when working remotely or across different locations, cultures, and time zones. The project manager should also involve the new team members in the communication planning process and solicit their feedback and preferences. This will help establish trust, rapport, and collaboration among the team members and foster a shared understanding of the project goals, roles, and expectations. References: (Professional in Business Analysis Reference Materials source and documents)
