Use Case

A use case is a detailed description of how a person or system interacts with a product or service to achieve a specific goal. It outlines the steps involved, the actions taken, and the outcomes expected. Use cases help clearly define functional requirements by illustrating real-world scenarios, making it easier for developers and stakeholders to understand what needs to be done. Think of a use case as a story that shows how users will use a system in practical situations, ensuring the final solution meets their needs effectively.
