scrum methodology

The roles in scrum are quite different from the traditional software methods. Clearly defined roles and expectations help individuals perform their tasks efficiently. In Scrum, there are three roles: product owner, Development Team, and scrum master. Together these are known as the scrum .

The scrum master helps the product group learn and apply Scrum to achieve business value. The Scrum Master does whatever is in their power to help the Team, Product Owner and organization be successful. The Scrum Master is not the manager of the Team members, nor are they a project manager, team lead, or team representative. Instead, the Scrum Master serves the Team; he or she helps to remove impediments, protects the Team from outside interference, and helps the Team to adopt practices. He or she educates, coaches and guides the Product Owner, Team and the rest of the organization in the skillful use of Scrum.

The Product Owner is responsible for maximizing return on investment (ROI) by identifying product features, translating these into a prioritized list, deciding which should be at the top of the list for the next sprint, and continually re-prioritizing and refining the list.
