What is a benefit of using use cases in requirements gathering?

Using use cases in requirements gathering is especially beneficial because they illustrate interactions between users and systems effectively. This approach helps stakeholders understand how users will interact with the system to accomplish specific tasks, which illuminates the functional requirements needed for the system's development. By depicting these user-system interactions, use cases clarify user expectations and system behavior in a straightforward manner, making them an invaluable tool for requirements elicitation.

The focus of use cases is on capturing the essence of user objectives and outlining scenarios for how the system should respond, thereby facilitating communication and consensus among stakeholders. This makes it easier to identify gaps or misunderstandings early in the project, ensuring that the final product meets user needs more accurately.

Other options present different aspects of requirements gathering but do not provide the same depth of insight into user interactions as use cases do. For instance, while some methods may simplify data into graphs or provide specific technical details, they do not capture the dynamic interactions that use cases highlight. Furthermore, interviews are an essential component of gathering requirements, and options suggesting their elimination overlook the need for direct user input and feedback.
