```python
class FallbackExecutor:
    """
    A class that implements a fallback strategy for executing tasks.
    
    If an initial execution fails due to an exception, it attempts
    to execute a backup plan defined by alternative_function.
    
    Parameters:
        function (Callable): The primary function to be executed.
        alternative_function (Callable, optional): The fallback function if the primary one fails. Defaults to None.

    Methods:
        run: Executes the provided function and handles exceptions by running the alternative function if available.

Note: The above code snippet includes a `random` import for the sake of example. In a real-world application, you might not want to include such imports in your FallbackExecutor class as they can introduce unexpected behaviors and dependencies.
