Developers are self-managing, which means that they decide how much work they can do in a Sprint, and how they will do it1. They manage the Sprint Backlog, which is the plan for how the Developers will achieve the Sprint Goal, and the single source of truth for the work to be done in the Sprint2. The Developers create and update the Sprint Backlog throughout the Sprint as more is learned[3][3]. The other options are not managed by the Developers, but by the Product Owner or the Scrum Team as a whole. The Product Owner is accountable for ordering the Product Backlog, which is an ordered list of everything that is known to be needed in the product4. The Product Owner also decides when to release the product, based on the value, risk, and stakeholder feedback5. The Scrum Team collaborates on inviting the stakeholders for the Sprint Review, which is an event where the Scrum Team and the stakeholders inspect the product Increment and adapt the Product Backlog. The Scrum Team also decides the Sprint length, which is the time-box within which the Scrum Team delivers a product Increment.
