Scrum Masters are often understood mostly as "team coaches," Yet, their role is vastly more important. The Scrum Guide emphasizes that Scrum Masters are responsible for leading and coaching organizations in the adoption of Scrum and causing change that increases the productivity of the Scrum Team.
And this makes sense; Scrum Masters are in a perfect position to see how missing skills, red tape, external dependencies, and other organizational impediments impact the ability of Scrum Teams to deliver working software every Sprint. Like car mechanics who try to fix cars by only looking at the tires while ignoring the broken engine, Scrum Masters who only focus on the team will miss the bigger, more important changes.
