def task_func(df, groups=['A', 'B', 'C', 'D', 'E']):
    """
    Analyzes the groups in a DataFrame by plotting a scatter plot of the ordinals against the values for each group.

    Parameters:
    df (DataFrame): The DataFrame with columns 'group', 'date', and 'value'.
    groups (list, optional): List of group identifiers. Defaults to ['A', 'B', 'C', 'D', 'E'].

    Returns:
    matplotlib.axes.Axes: The Axes object with the scatter plot.
    The Axes object will have a title 'Scatterplot of Values for Each Group Over Time', 
               x-axis labeled as 'Date (ordinal)', and y-axis labeled as 'Value'.


    Raises:
    ValueError: If 'df' is not a DataFrame or lacks required columns.

    Requirements:
    - pandas
    - matplotlib.pyplot
    - itertools

    Example:
    >>> df = pd.DataFrame({
    ...     "group": ["A", "A", "A", "B", "B"],
    ...     "date": pd.to_datetime(["2022-01-02", "2022-01-13", "2022-02-01", "2022-02-23", "2022-03-05"]),
    ...     "value": [10, 20, 16, 31, 56],
    ...     })
    >>> ax = task_func(df)
    >>> ax.figure.show()  # This will display the plot
    """

instruct prompt

Analyzes the groups in a DataFrame by plotting a scatter plot of the ordinals against the values for each group.
The function should raise the exception for: ValueError: If 'df' is not a DataFrame or lacks required columns.
The function should output with:
    matplotlib.axes.Axes: The Axes object with the scatter plot.
    The Axes object will have a title 'Scatterplot of Values for Each Group Over Time',
    x-axis labeled as 'Date (ordinal)', and y-axis labeled as 'Value'.
You should write self-contained code starting with:
