    Handling

    The criticality of the System is defined and justified.

    Requirements with regard to quality characteristics from a user-level point of view have to be defined.

    The basis is /DIN ISO IEC 9126/.
    The external specifications as defined when the order was placed are the starting point of the activity.

    ---------- The following part is an extension of the original printed version of GD 250 -----------
