Guide on Scrum Roles

'Importance:
Understanding Scrum Roles is crucial as it forms the backbone of any Scrum project. These roles divide responsibilities within a Scrum Team and ensure efficient project progress.

What it is:
Scrum Roles include the Product Owner, the Scrum Master, and the Development Team. The Product Owner manages the product backlog and is responsible for the return on investment. The Scrum Master facilitates Scrum to the organization and removes any impediments for the team. The Development Team consists of professionals who do the work of delivering a potentially shippable Increment.

How it works:
The Product Owner sets the product vision and communicates it to the Development Team. The Scrum Master ensures that the team adheres to Scrum theory, practices, and rules. The Development Team designs and delivers the product Increment in each Sprint.

3) Understand the values that drive these roles, especially the values listed in the Agile Manifesto.
