As said above, both Business Design and Technical Design cover an evaluation of existing components from the business and technical point of view, resulting in a preselection of potentially suitable components for the system. The Specification subresult Component Test contains the results and test logs of these components with respect to the user requirements and the chosen system architecture. Note that such tests should be performed as soon as the specification of a component is available in order to avoid problems during system integration.

Some of the desired components may simply be ordered whereas other components are not available at all and must be developed. The Component Assignment subresult specifies which components are to be developed in the current project and which components are ordered from external component suppliers or in-house profit centers. If a component is to be developed outside of the current project, a new, separate result structure has to be set up. Note the close correspondence between Architecture Specification and Component Specification on the one hand, and Interaction Analysis and Responsibility Analysis on the other hand. It allows for a clear hand-over of a component specification to a component developer outside the project.
