The fundamental organisational unit of Scrum is the Scrum Team. They are accountable for creating a valuable, useful Increment every Sprint. Inside the Scrum Team there are 3 accountabilities:
- Product Owner
- Scrum Master
- Developers
Scrum Teams are cross-functional. They have all the skills necessary to create value each Sprint. They are self-managing and they internally decide who does what, when, and how.
The Scrum Team is small, typically 10 or fewer people to enable better communication better and increased productivity. Within a Scrum Team, there are no sub-teams or hierarchies.
The Product Owner
The Product Owner is accountable for maximising the value of the product resulting from the work of the Scrum Team. Although others may assist, they are accountable for effective Product Backlog management.
For Scrum to succeed and value to be delivered efficiently, the organisation must recognise, respect and support the Product Owner.
The Product Owner is accountable for “what” is developed.
Developers
The Developers are committed to creating any aspect of a usable Increment each Sprint. They are accountable for the Sprint Backlog and for the technical quality of the product.
The Developers include anyone who works to create the product, whatever skillset they may have.
They are accountable for “how” the product is developed.
The Scrum Master
The Scrum Master is accountable for establishing Scrum and helping everyone understand and use it, both within the Scrum Team and the organisation.
The Scrum Master is accountable for the Scrum Team’s effectiveness. They help create the conditions for effective delivery through facilitation, coaching, teaching and mentoring. They provide delivery leadership whilst at the same time acting as a servant who helps remove impediments to the Scrum Teams progress.
The Scrum Master is accountable for the “who”, for how people use Scrum and interact and collaborate to deliver value.
