Two team members have been arguing openly in meetings and individually met with the sponsor to push their ideas, making decisions without informing the project manager or the rest of the team. Which two actions should the project manager take? (Choose two.)

The project manager must address disruptive behavior directly. Reinstating ground rules ensures everyone understands expected conduct, promoting a respectful and productive environment. Addressing the issue individually with each team member allows for a private discussion about their specific actions, their impact on the team, and a path forward, which is crucial for conflict resolution and behavioral correction. Telling them to resolve it themselves abdicates responsibility and is unlikely to work given their current behavior. Talking to other project managers for advice is a good general practice but doesn't directly address the immediate conflict. Speaking with their functional managers might be necessary if the behavior persists, but the project manager should first attempt to resolve the issue directly with the team members involved.
