This answer is based on the PMBOK® Guide, which is one of the reference materials for the PMP exam1, and the PMI Guide to Business Analysis, which is one of the reference materials for the PMI-PBA exam2. According to the guides, the project manager is responsible for managing the project team, which includes developing, leading, and motivating the team members, as well as resolving any conflicts or issues that may arise among them12. The project manager should also establish and enforce the ground rules for the project team, which are the agreed-upon standards of behavior and expectations for the team members, such as communication protocols, decision-making processes, meeting guidelines, and conflict resolution methods12. When the project manager observes that two team members have been arguing with each other openly at meetings and bypassing the project manager to influence the sponsor, this indicates a serious breach of the ground rules and a potential threat to the project performance and harmony. The project manager should take the following two actions to address this situation:
Reiterate ground rules at the next meeting and ensure that all team members are clear about these rules. This action will remind the team members of their roles and responsibilities, and the expected norms of conduct for the project team. It will also reinforce the authority and accountability of the project manager, and the importance of following the agreed-upon procedures for communication and decision-making. This action will help to prevent further escalation of the conflict and restore trust and respect among the team members12.
Address the behavioral issue with each team member. This action will allow the project manager to understand the root cause of the conflict, and the perspectives and interests of each team member. It will also enable the project manager to provide constructive feedback, coaching, or counseling to each team member, and to facilitate a collaborative resolution that satisfies both parties and aligns with the project objectives. This action will help to improve the performance and morale of the team members, and to foster a positive and productive team culture12.
The other options are not appropriate because they do not address the problem effectively or ethically. Asking the team members to work it out themselves is not a responsible or proactive approach, as it may lead to further deterioration of the relationship and the project outcomes. Discussing this situation with other project managers and asking for advice is not a confidential or respectful way to handle the issue, as it may expose the team members to gossip or criticism, and undermine their trust and credibility. Discussing the behavior directly with their managers and requesting them to correct the behavior is not a fair or empowering way to deal with the issue, as it may create a perception of blame or punishment, and damage the rapport and autonomy of the team members.
