Quick Definition:
A User Story is a brief, informal description of a feature from the perspective of the end user. Acceptance Criteria are the specific conditions that a user story must meet to be considered complete and accepted by the stakeholder.
Writing User Stories
A typical user story follows this format: “As a [type of user], I want [some goal] so that [some reason].” This keeps the focus on the user’s needs rather than technical details.
Defining Acceptance Criteria
Acceptance criteria should be clear, measurable, and testable. They define the “boundaries” of the user story and ensure that everyone has a shared understanding of what “done” looks like.
