Correct Answer: BTo enhance project team effectiveness in a global virtual team facing communication issues, the project manager should identify the root cause of these communication issues. Understanding the root cause is essential to address the problem effectively and implement the right solutions. Simply colocating the team or increasing the frequency of communications may not resolve the underlying issues, and scheduling a communications control board meeting might not be beneficial if the root causes are unknown. Identifying the root cause allows the project manager to tailor specific strategies to improve communication and prevent missed deadlines.
