Use case development involves creating detailed scenarios that describe how users will interact with the system to achieve specific goals. These use cases serve as a blueprint for the development process, ensuring that all functional requirements are clearly defined and aligned with user needs and business objectives.
We begin by identifying the primary actors (users or other systems) that will interact with the system and defining their specific goals. Each use case outlines a sequence of actions performed by the user and the system to achieve these goals. We also include alternate flows to cover exceptional situations and edge cases.
Use cases are written in simple, understandable language, making them accessible to both technical and non-technical stakeholders. This clarity helps bridge the gap between business requirements and technical implementation, ensuring that everyone involved has a shared understanding of the desired outcomes.
