The Scrum Master plays a crucial role in Scrum project management. They do not manage the team but rather act as a facilitator between the team and the client. They protect the team from external interruptions and help them to maintain focus on the tasks. They ensure that the Scrum team adheres to Scrum theory, practices, and rules. They also help the team to improve and get better with each Sprint. The Scrum Master furthermore facilitates communication and resolves conflicts to ensure smooth project execution.

User Stories are an integral part of Scrum and express requirements from an end user’s perspective. They are a simple technique for describing the desired functionality from the viewpoint of the user. User Stories focus on the value that the requirement brings to the user, rather than on system implementation. In Scrum, the Product Backlog is populated with User Stories, which are chosen, implemented, and delivered incrementally, leading to the development of usable products at the end of each Sprint.

The Scrum Team is comprised of a Product Owner, the Development Team, and a Scrum Master. Each role has unique responsibilities and they all work together to develop, deliver and sustain a product. In Scrum, teams are self-organizing, meaning they decide themselves how to best achieve their tasks, rather than being directed by others outside the team.
