Scrum is a framework for managing complex projects and the Scrum Master is responsible for the overall success of a project. They are also responsible for creating and maintaining a safe, healthy, and productive environment in which their team members can do their best work. The Scrum Master role has evolved over the years to include more responsibilities such as planning, organizing, facilitating meetings, and coaching. Scrum Masters can be divided into three categories based on their focus: culture management (building an environment that fosters productivity), project management (planning and executing plans), or process management (ensuring compliance with company standards).
