A Scrum Master is a facilitator and servant leader in an Agile Scrum development team. Their primary role is to ensure the team is following the Scrum framework and to remove any impediments that may be blocking the team's progress. The Scrum Master also facilitates Scrum events, such as sprint planning, daily stand-up, sprint review, and sprint retrospective, and coaches the team on the principles of Agile and Scrum. The ultimate goal of a Scrum Master is to help the team deliver high-quality products in a sustainable and efficient manner.
