The Scrum Framework makes a clear distinction between the Product Backlog and the Sprint Backlog.
The Product Backlog is defined as:
•The requirements
•A list of all desired work on the release
•Ideally expressed such that each item has value to the users or customers of the product
•Expressed as customer-oriented features (not as technical tasks !)
•Prioritized by the product owner
•Reprioritized at the start of each sprint
The Sprint backlog is defined as:
- Top Priority features from the Product Backlog that would be developed by the end of the Sprint
- Members volunteer to work on task
