Use cases and user stories are useful for identifying what?

Use cases and user stories are effective tools for identifying the relationships between objects in a system. They provide a narrative that describes how users interact with the system, highlighting the roles of different objects and their interactions. By breaking down the functionality that users expect, these tools clarify how various components or classes will work together to fulfill specific user needs.

Through this narrative approach, developers can understand the purpose and behavior of each object, leading to better-defined relationships such as associations, dependencies, or aggregation. This ultimately aids in constructing a cohesive object-oriented design that reflects the real-world interactions of the users within the software.

The other options focus on more technical aspects of programming. Methods of a class, data types of attributes, and exceptions in code pertain to specific implementation details that do not directly relate to the user-centered perspective provided by use cases and user stories. These tools help in understanding how users will navigate the system rather than detailing the internal workings of the code itself.
