Continue ... Scrum
The first step in Scrum is for the Product Owner to articulate the product vision. Eventually,this evolves into a refined and prioritized list of features called the Product Backlog.
The subset of the Product Backlog that is intended for the current release is known as the Release Backlog, and in general, this portion is the primary focus of the Product Owner.
Scrum does not define techniques for expressing or prioritizing items in the Product Backlog and it does not define an estimation technique. A common technique is to estimate in terms of relative size (factoring in effort, complexity, and uncertainty) using a unit of “story points”
or simply “points”.
The Product Backlog items for the upcoming next several Sprints should be small and fine-grained enough that they are understood by the Team, enabling commitments made in the Sprint Planning meeting to be meaningful; this is called an “actionable” size.
