Use case template: Downloadable example & how to write one

A use case is a detailed narrative detailing how users interact with a system to achieve specific goals, often used in software development, project management, and business analysis to define requirements, user needs, and system behaviors. Documented in textual, tabular, or diagrammatic formats, use cases guide development by outlining main flows and alternative scenarios, facilitating better communication across teams and stakeholders. They help in early identification of potential issues, ensuring that systems meet user needs and expectations, while also distinguishing themselves from user stories and feature lists by providing a comprehensive roadmap of user interactions. Different professionals, including product managers, developers, and business analysts, contribute to use cases, which serve as foundational documents for design processes, technical development, and testing. Advanced modeling techniques, such as UML diagrams and alternative flow scenarios, enhance the robustness of use cases, making them versatile tools for agile and waterfall environments alike.
