    Explanation
    The correct answer outlines the structure of a typical use case in the usual order. It starts with a description of the use case, followed by pre-conditions that must be met before the use case can be executed. Then, the main flow of the use case is described, which represents the normal sequence of steps. Alternative flows are then described, which represent different paths or variations in the main flow. Exceptions are then outlined, which are unexpected events or errors that may occur during the execution of the use case. Finally, post-conditions are described, which are the outcomes or results of the use case.

    • D.

      Reusuing one use case's steps inside another use case

    Correct Answer
    D. Reusuing one use case's steps inside another use case
    Explanation
    Including a use case refers to the practice of reusing the steps from one use case in another use case. This allows for the efficient and effective representation of common functionalities or processes across different scenarios. By reusing steps, it eliminates the need to duplicate the same actions or interactions, promoting consistency and reducing redundancy in the overall system design. This approach also enhances maintainability, as any changes or updates made to the reused use case will automatically reflect in all instances where it is included.
