A user story is a concise description of a feature or functionality that a user wants to achieve in an application. A good user story has three characteristics: it can be tested, it reflects the business value the client receives, and it is easy to understand. It can be tested means that the user story has clear and measurable acceptance criteria that verify whether it meets the user’s expectations. It reflects the business value the client receives means that the user story explains why the feature or functionality is important or beneficial for the user or the business outcome. It is easy to understand means that the user story uses simple and consistent language that avoids technical jargon or ambiguity.
