You are the Scrum Master of a Scrum Team that has one Developer who disagrees with team decisions. Their disagreements are becoming disruptive and slowing progress. The Developer often returns to earlier team decisions and re-opens the issue.

What are two ways to go about this problem? (Choose two.)

A. You go to the Human Resources department and ask them to have a conversation with the Developer based on the issues the team has raised.
B. You organize an offsite team building activity to establish a foundation of trust. You observe whether the problem persists after the offsite activity.
C. You take the Developer aside to express your concern over their disagreements and tell them to act as a team player and to comply with the team's decision.
D. To every team member expressing this concern you suggest raising this with the full team. You offer to help initiate the conversation but not to resolve the concern yourself.
E. At the Sprint Retrospective you observe whether the topic is raised. If it does not happen, you check on how comfortable everybody is with the way team decisions are made.
