Use cases

Use cases are descriptions of how people or systems will interact with a product or service to achieve specific goals. They outline scenarios in which a user engages with a product, detailing the steps taken and the expected outcomes. For example, a use case for an online shopping website might describe the process of selecting items, adding them to a cart, and completing the purchase. This helps developers understand user needs, prioritize features, and design a better user experience by focusing on real-world applications of the solution.
