Scrum is an Agile framework used for managing and completing complex projects. It is a collaborative approach that emphasizes teamwork, communication, and adaptability. In Scrum, there are two key roles: the Scrum Master and the Product Owner.

The Scrum Master is responsible for facilitating the Scrum process and ensuring that it is followed by the team. The Scrum Master acts as a coach and mentor to the team, helping them to understand the Scrum framework and guiding them in their use of it. The Scrum Master ensures that the team is focused, motivated, and that they are working together effectively. They also remove any obstacles that the team may encounter during the project, to ensure that the project progresses smoothly.

The Product Owner is responsible for managing the product backlog, prioritizing features, and making decisions about what features to include in each release. The Product Owner is the person who represents the interests of the stakeholders, and they work closely with the development team to ensure that the product is meeting the needs of the end-users. The Product Owner is responsible for ensuring that the product backlog is up-to-date, and that the features in the backlog are well-defined and understood by the development team.

Both roles are essential in the Scrum framework, and they work closely together to ensure the success of the project. The Scrum Master facilitates the process, while the Product Owner is responsible for the product backlog and ensuring that the team is building the right features. Together, they help the development team to deliver high-quality products in an Agile environment.
