How should a scrum team determine if the stories in a sprint are complete?

A scrum team should determine if the stories in a sprint are complete by having a documented and agreed-upon definition of done. This definition serves as a shared understanding among the team members about what it means for work to be considered complete. It encompasses all necessary criteria, such as coding, testing, documentation, and any other deliverables that need to be met for a story to be accepted by the product owner.

Having a clear definition of done helps ensure consistency and quality across the team's work. It reduces ambiguity and aligns expectations, enabling team members to assess whether they have truly finished their tasks before they are presented during sprint reviews. This practice fosters accountability within the team and supports continuous improvement, as the definition of done can evolve based on team experiences.

The other responses do not establish a reliable framework for determining completeness, which is essential for maintaining quality and standardization in scrum practices.
