The best approach to resolving this conflict is collaborating, as it encourages open communication and active participation from all team members. In this case, the graphic designer's non-participation is causing frustration within the team. The Scrum Master should facilitate a discussion where the designer can express their concerns, and the team can share why their attendance in meetings is important. By collaborating, the Scrum Master can help find a solution that addresses both the designer's needs and the team's expectations, ensuring better teamwork and alignment moving forward. This approach encourages mutual respect and fosters a cooperative environment.
