A use-case driven process is a software development approach that focuses on identifying and developing use-cases that describe how a user or system interacts with a software application in order to achieve specific goals or objectives. A use case is a description of a specific action or set of actions that a system or user might perform to accomplish a task or achieve a specific goal. The benefits of use-case driven development include improved communication and collaboration among team members, clearer understanding of project requirements, better alignment of software functionality with user needs, and improved testing and validation of software functionality.
