    If activity QA4.1 - Determination of Assessability results in a negative decision (assessability is not possible) then the object to be assessed is returned to SD, QA, CM or PM and has to be revised.

    The Assessment Report is the result of the product assessment with regard to the contents; it shows among other things whether the product has been given the state "accepted" or "b. proc.".

    The project management is to be informed about the assessment result.

    It is important to state at this point that the object to be assessed must not have been created by the Assessor himself.

    (1) Method SIMU is to be applied if reliability requirements are high nd the use conditions are so complex that static investigations with regard to feasibility and resource requirements are not sufficient.

    (2) Method SIMU is to be applied if the test cannot completely handle the performance and error proof since - among other things - special limitations, assumptions, and environmental conditions have to be taken into consideration.

    (3) Methode STAT is to be applied if contents of the object to be assessed are structured according to a standard formalism.

    (4) Method T is to be applied if contents of the object to be assessed are structured according to a specified formalism allowing a dynamic execution.

    (5) Method T is to be applied if automated assessment procedures are to be used.
