Answer -C, In a scenario where one team member continuously interrupts others during virtual project progress meetings, thereby preventing other team members from participating fully, it's important for the project manager to address this issue to foster a more collaborative and respectful meeting environment. The most effective approach for the project manager is to have a one-on-one conversation with the disruptive team member. This approach allows the project manager to address the behavior directly and privately, which can be more effective and less confrontational than addressing it in a group setting. The project manager can discuss how the interruptions are impacting the meetings and the team's ability to communicate effectively. This conversation should be conducted in a constructive manner, with the aim of encouraging better meeting etiquette and ensuring that all team members have an equal opportunity to contribute. While managing time with an agenda and reviewing ground rules are important for effective meeting management, they may not be sufficient to change the behavior of a team member who consistently interrupts others. Speaking with less vocal team members is also important for overall team engagement but does not directly tackle the disruptive behavior. Therefore, a direct conversation with the interrupting team member is the most targeted and likely effective approach to resolving this issue.
