What does the term AC refer to in the context of user stories?

The term AC in the context of user stories stands for Acceptance Criteria. Acceptance Criteria are specific conditions or requirements that must be met for a user story to be considered complete and acceptable by stakeholders. They serve as a clear guide to the development team regarding what functionality must be implemented, ensuring that everyone involved has a shared understanding of the desired outcome. Including well-defined acceptance criteria helps to prevent ambiguity and sets the expectations that clarify what success looks like for that particular user story. This is essential for effective testing and validation processes, as it allows team members to determine if the product meets the defined conditions before it is delivered.
