During the second iteration, a conflict between two team members is affecting a deliverable. How should the project manager handle this to prevent project impact?

The project manager's role includes facilitating conflict resolution. Scheduling a meeting to understand the root cause and guide the team members toward a mutually acceptable solution is the most effective and proactive approach. This fosters collaboration and empowers the team to resolve their own issues, which is crucial in agile environments. Sending warnings or escalating immediately to functional managers without attempting to resolve it first can damage team morale and trust, and is an avoidance technique rather than a resolution strategy. Requesting replacements is an extreme measure that should only be considered after all other resolution attempts have failed, as it can disrupt the project and incur additional costs and delays.
