Final answer:
The definition of "Done" ensures consistency in understanding among team members, defines the scope of work for a Sprint, and sets quality standards for completed work.
Step-by-step explanation:
The purpose of a definition of "Done" in the context of a Development Team selecting Product Backlog items for a Sprint includes several phrases. Three phrases that best describe the purpose are:
- Ensures consistency: It establishes a common understanding among team members and stakeholders what it means for work to be considered "Done."
- Defines the scope of work: It clarifies what is included in a Product Backlog item, and what needs to be completed during the Sprint to satisfy the item's requirements.
- Guarantees quality: It sets a quality standard for the finished work, ensuring that all work meets this bar before being called "Done."
While "Sets realistic deadlines" is relevant to project planning, it is not typically the focus of the definition of "Done", which is more concerned with the state of the work rather than time constraints.
