This is where the calculated requirements are investigated and assessed with regard to their feasibility. Based on the Software Architecture and the description of the SW Component/SW Module and Database, the required resources and the required time have to be investigated. With regard to the characteristics of the SW Unit defined in the Technical Requirements, the discovered performance characteristics should have sufficient possibilities left to realize the maintenance and modification measures without redesign at some later time. If these possibilities are not given the realization decisions have to be exactly assessed at this point.

Being defined

Notes:

(1) Method ACC must be applied according to [ITSEC].

(2) 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.
