You are leading an agile project team that has just completed their first sprint.

You are leading an agile project with a newly formed team. During the first two sprints, you notice that one team member, Sarah, consistently remains quiet during daily stand-ups and retrospectives. When she does speak, her contributions are valuable, but she appears uncomfortable in group settings. Other team members have started making decisions without her input. The team's velocity is acceptable, but you sense Sarah's potential is not being fully utilized. What should you do first to address this situation?

An agile team of eight members has been working together for three months.

These disagreements sometimes delay decisions and create tension. Other team members have started avoiding technical discussions when both developers are present. Yesterday, a refinement session ended early because the disagreement escalated into a heated argument. What is the most appropriate action for addressing this conflict?
