Scrum Roles

Scrum defines exactly three roles. Each role carries specific responsibilities, and no role overlaps with another.

Product Owner

The product owner manages the product backlog, which lists everything the product needs. This person decides what the team builds and in what order. The product owner talks regularly with customers and stakeholders to understand their needs.

Scrum Master

The Scrum Master helps the team follow Scrum rules correctly. This person removes obstacles that block the team's progress. A Scrum Master also shields the team from outside distractions during a sprint.

Development Team

The development team builds the actual product. This group includes everyone needed to turn an idea into a working result, such as designers, coders, and testers. The team organizes its own daily work without needing a separate manager.

A Simple Diagram of the Three Roles

   Product Owner          Scrum Master
   (what to build)        (removes blockers)
          \                    /
           \                  /
            Development Team
             (builds the work)

Layman's Example

Picture a film production. The producer decides which scenes matter most and controls the budget, similar to a product owner. The assistant director keeps the set running smoothly and solves problems on the spot, similar to a Scrum Master. The actors and camera crew create the actual footage, similar to the development team.

No Overlapping Authority

The product owner never tells developers exactly how to build a feature. The Scrum Master never assigns tasks to team members. Each role respects the boundaries of the other roles, which keeps the team functioning smoothly.

Key Takeaway

Scrum relies on three distinct roles working together. The product owner decides priorities, the Scrum Master removes obstacles, and the development team delivers the work.
