This example shows in a simple manner how the characteristics/requirements can be made transparent based on requirements, constraints, qualities and principles. This example shows how the characteristics of the different xBB can be mapped based on ArchiMate concepts. This will soon become an important mechanism in the various xBB catalogues. In addition to this approach, the characteristics can also be elaborated via the internal characteristics of the entities in EA. Such as requirements, constraint and scenario. Finally, there is the option to use tagged values. The working group has determined that making associations between ArchiMate concepts is preferable. If an elaboration with ArchiMate concepts is insufficient and you want to rely on internal properties or tagged values, this must be short-circuited.
