A Scrum Master is a key role in the Scrum framework, which is used for managing and completing complex projects, particularly in software development. The Scrum Master acts as a facilitator, helping the Scrum Team understand and implement Scrum practices effectively. They ensure that the team follows the agreed-upon processes and removes any obstacles that may hinder progress. In addition to supporting the team, the Scrum Master also serves as a liaison between the team and other stakeholders, promoting collaboration and communication. They help create a productive environment where the team can focus on delivering high-quality work in short, iterative cycles known as sprints.
