A user story is basically a step in the user journey and all user stories are independent. The concept map below gives an overview of the agile tools supported by Visual Paradigm. Conversely, use cases tend to give more of an overview of a larger system functionality. A Use-Case model consists of a number of model elements. User Story Vs. Use Cases. Like user stories, a use case describes how a user might interact with a product to solve a specific problem. User Stories are focused on capturing the requirements without addressing the details that may change later. Use Cases contain equivalent elements: an actor, flow of events and post conditions respectively (a detailed Use Case template may contain many more other elements).
