    This activity has to define the requirements for the technical functionality of the SW Unit/HW Unit.

    The functionality to be realized by the SW Unit/HW Unit has to be identified and to be established. The requirements with regard to the reactions of the SW Unit/HW Unit in a normal and in an exceptional case must be defined.

    Here the functionality of HW Units also includes electrical, mechanical and optical function parts.

    (1) Method ER is to be applied for information systems.

    (2) The methods have to be applied in object-oriented developments.

    (3) Method STMO is to be applied for the dynamic system modeling in object-oriented procedures.

    (4) Method SBM is to be applied for realtime applications or respectively distributed systems with a high level of criticality. Method FNET is to be applied for information systems.

    (5) Method ELH is to be applied for information systems.

    (6) Method DTAB is to be applied for the description of complex facts and circumstances.

    (7) Method STM is to be applied if complex situations have to be considered during the run of the function or the process.
