The system design stage is a mixture of the requirements definition and design specification phases of ARIS, whereby the emphasis tends to be placed on the design specification. The neglect of the requirements definition can be explained by the fact that the bUSiness analysis is carried out so thoroughly. It is true that it is principally handled descriptively (actual analysis), however, the concepts and interdependences developed can be carried over to the planned concept. For this reason, the ''business analysis" can be regarded as equivalent to large parts of the requirements definition.
