What two attributes are optional for a Product Backlog Item?

The correct choice highlights that Dependencies and Test descriptions are optional attributes for a Product Backlog Item (PBI), which means they are not strictly required for every PBI, even though they can enhance understanding and clarity regarding each item.

Dependencies refer to items that are reliant on others, and while recognizing them can help prioritize work, they are not necessary for defining the completeness of a PBI. Similarly, Test descriptions can aid in outlining how a PBI will be validated but are not mandatory elements of the backlog item itself.

By stating that these attributes "will prove PBI Item completeness when 'Done'," it suggests that while helpful for transparency and quality assurance, they do not impede the fundamental purpose of defining a PBI. Scrum emphasizes the ability to decompose work into manageable pieces, allowing flexibility in how these PBIs are structured.

Other options present attributes that are also beneficial for PBIs but do not capture the same nuance of being optional. For instance, Acceptance Criteria is crucial for conveying the expectations for a PBI's acceptance, making it more essential than optional in typical Scrum practice. Similarly, while Status Updates might provide context, they are generally seen as operational rather than a requirement tied to the PBI's definition itself.

Thus, understanding
