NAV-1 Overview and Summary Information
NAV-1 defines the architecture (Architecture Description) contained in a HOPEX library. All items of the architecture are automatically defined in the associated library. Additional properties define the general purpose of the architecture.
At the top level of the architecture description, the designer describes the enterprise structure that supports the architecture design and performance. Each item of this structure can be linked to a capability master plan that corresponds to the enterprise vision at the appropriate level.
NAV-1 metamodel
An enterprise structure is composed of Enterprise Phase items that contain sub-items (Enterprise Phase Component). This is a whole-part model.
Note that compared with the 2009 SP4 release, the use of org-units with an Enterprise type is replaced by a dedicated notion (Enterprise Phase). For existing models, a conversion tool must be applied that creates as many enterprise phases as corresponding org-units. The previous org-units must be deleted by the user. The structure diagrams used to describe previous org-units are not converted since the enterprise phase should not introduce interactions between its sub-items like an org-unit model permits.
