Scrum Team

Scrum Team

The fundamental unit of Scrum is a small team of people, a Scrum Team. The Scrum Team consists of one Scrum Master, one Product Owner, and Developers. Within a Scrum Team, there are no sub-teams or hierarchies. It is a cohesive unit of professionals focused on one objective at a time, the Product Goal.


Scrum Teams are cross-functional, meaning the members have all the skills necessary to create value for each Sprint. They are also self-managing, meaning they internally decide who does what, when, and how.

The Scrum Team is small enough to remain nimble and large enough to complete significant work within a Sprint, typically 10 or fewer people. In general, we have found that smaller teams communicate better and are more productive. If Scrum Teams become too large, they should consider reorganizing into multiple cohesive Scrum Teams, each focused on the same product. Therefore, they should share the same Product Goal, Product Backlog, and Product Owner.


The Scrum Team is responsible for all product-related activities from stakeholder collaboration, verification, maintenance, operation, experimentation, research and development, and anything else that might be required. They are structured and empowered by the organization to manage their own work. Working in Sprints at a sustainable pace improves the Scrum Team’s focus and consistency.


The entire Scrum Team is accountable for creating a valuable, useful Increment for every Sprint. Scrum defines three specific accountabilities within the Scrum Team: the Developers, the Product Owner, and the Scrum Master.

1. Developers

Developers are the people in the Scrum Team that are committed to creating any aspect of a usable Increment for each Sprint.


The specific skills needed by the Developers are often broad and will vary with the domain of work.


However, the Developers are always accountable for:
● Creating a plan for the Sprint, the Sprint Backlog;
● Instilling quality by adhering to a Definition of Done;
● Adapting their plan each day toward the Sprint Goal; and,
● Holding each other accountable as professionals

2. Product Owner

The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team. How this is done may vary widely across organizations, Scrum Teams, and individuals.

The Product Owner is also accountable for effective Product Backlog management, which includes:
● Developing and explicitly communicating the Product Goal;
● Creating and clearly communicating Product Backlog items;
● Ordering Product Backlog items; and,
● Ensuring that the Product Backlog is transparent, visible, and understood.

The Product Owner may do the above work or may delegate the responsibility to others. Regardless, the Product Owner remains accountable.


For Product Owners to succeed, the entire organization must respect their decisions. These decisions are visible in the content and ordering of the Product Backlog, and through the inspectable Increment at the Sprint Review.


The Product Owner is one person, not a committee. The Product Owner may represent the needs of many stakeholders in the Product Backlog. Those wanting to change the Product Backlog can do so by trying to convince the Product Owner.

3. Scrum Master

The Scrum Master is accountable for establishing Scrum as defined in the Scrum Guide. They do this by helping everyone understand Scrum theory and practice, both within the Scrum Team and the organization.


The Scrum Master is accountable for the Scrum Team’s effectiveness. They do this by enabling the Scrum Team to improve its practices, within the Scrum framework.


Scrum Masters are true leaders who serve the Scrum Team and the larger organization.


The Scrum Master serves the Scrum Team in several ways, including:
● Coaching the team members in self-management and cross-functionality;
● Helping the Scrum Team focus on creating high-value Increments that meet the Definition of Done;
● Causing the removal of impediments to the Scrum Team’s progress; and,
● Ensuring that all Scrum events take place and are positive, productive, and kept within the timebox.

The Scrum Master serves the Product Owner in several ways, including:

● Helping find techniques for effective Product Goal definition and Product Backlog management;
● Helping the Scrum Team understand the need for clear and concise Product Backlog items;
● Helping establish empirical product planning for a complex environment; and,
● Facilitating stakeholder collaboration as requested or needed.

The Scrum Master serves the organization in several ways, including:
● Leading, training, and coaching the organization in its Scrum adoption;
● Planning and advising Scrum implementations within the organization;
● Helping employees and stakeholders understand and enact an empirical approach for complex work; and,
● Removing barriers between stakeholders and Scrum Teams.
