Use Case Analysis is a technique used in software development to identify and clarify the requirements of a system. It involves creating detailed descriptions of how users, referred to as actors, will interact with the system to achieve specific goals. Each use case outlines the steps taken by the actor and the system's responses, helping to visualize user interactions and system functionality. This analysis helps teams understand user needs and prioritize features effectively. By focusing on real-world scenarios, stakeholders can ensure that the final product meets user expectations and delivers value. Use Case Analysis is essential for creating user-centered designs and improving overall system usability.
