A project manager works with a global virtual team.

Identifying the root cause of communication issues is the first step to enhance project team effectiveness. The project manager should use tools and techniques such as interviews, surveys, or root cause analysis to understand the factors that are affecting the communication among the team members. These factors could include cultural differences, language barriers, time zones, technology limitations, or personal preferences. Once the root cause is identified, the project manager can implement appropriate solutions to improve the communication and collaboration within the team. Implementing team colocation to improve communication is not a feasible option for a global virtual team, as it would incur high costs and logistical challenges. Initiating daily communication of project progress is a good practice, but it does not address the underlying communication issues. Scheduling a communications control board meeting is not relevant to the question, as it is a mechanism to monitor and control the communication management plan, not to enhance the team effectiveness. References: Project Management Professional Sample Questions, page 11, question 91.
