What are Scrum requirements?

Scrum does not characterize just what shape necessities are to require, but essentially says that they are accumulated into the Item Backlog, and alluded to generically as “Product Backlog Items,” or “PBIs” for short. Given the time-boxed nature of a Sprint, we will also gather that each set ought to require essentially less time to execute than the length of the Sprint. Most Scrum ventures borrow the “XP” (Extreme Programming) practice of depicting a feature request as a “User Story,” although a minority uses the more seasoned concept of a “Use Case.” We are going to go with the larger part view here, and depict three reasonably-standard requirements artefacts found in Product Backlogs.
