Which position serves as the agile team's Scrum coach and helps improve Scrum application?

The Scrum master plays a crucial role in an agile team by serving as the Scrum coach, guiding the team in applying Scrum principles effectively. This position helps facilitate Scrum practices, ensuring that the team fully understands the framework and adheres to its rules and values. The Scrum master acts as a servant leader, supporting the team by removing obstacles, promoting collaboration, and fostering an environment where the team can thrive.

In addition to these responsibilities, the Scrum master often engages in coaching not only the team but also stakeholders and the organization about agile practices, enabling continuous improvement and a better understanding of Scrum. This enhancement of Scrum application ultimately leads to higher productivity and more successful project outcomes.

Other roles mentioned, such as a product manager, end-user, and architect, do not specifically focus on the application of Scrum as their primary function. A product manager is mainly concerned with defining product vision and prioritization of features, an end-user provides feedback from a user perspective, but is not involved in coaching or facilitating process, and an architect focuses on the technical structure of the project rather than the Scrum framework. Hence, the Scrum master is unequivocally the position responsible for serving as the Scrum coach in this context.
