Explanation
= According to the PMBOK Guide, 7th edition, one of the project manager's roles is to facilitate collaboration among team members and stakeholders1. This includes resolving conflicts and promoting a positive team environment2. Therefore, the best option for the project manager is to encourage both team members to meet as soon as possible and resolve the problem. This way, the project manager can help them understand each other's perspectives, find common ground, and reach a mutually acceptable solution3. Reporting the disruptive team member to the HR department (option A) may escalate the conflict and damage the trust and relationship between the team members. Suggesting that the team member ignore the disruptive team member and focus only on the work (option B) may not address the root cause of the problem and may lead to further resentment and frustration. Monitoring the situation for a few weeks to determine if the disruptive team member's attitude changes (option C) may not be effective, as the conflict may worsen over time and affect the team's performance and morale.
