The Proact Toolkit provides an extended set of models to support Target Architecture Development. Target Architectures are always linked back to their appropriate "root" capability in the associated reference model. In most cases there are specific models to support Target Architecture Development.

The Systems and Technology Views provide a number of specific target models used for creating and navigating through planned future capabilities. The Target Systems models identify the information exchanges between Target Systems, Data Stores and include the use of Integration Systems, such as Hubs, Workflow Management Systems, Business Objects, Data Warehouses and Portals. The figure below shows an example of a System Information Exchange Model.

The Proact Framework contains a corresponding Target System Technology Model comprised of standard Target Devices and associated Networks. The work on Target Architectures for the Technology View starts with identification of target technology services for the IT infrastructure as a whole. The figure below shows an example of a Systems Technology Model for a specific Target System.

It is important not to take enterprise target architecture models too deep. As the above examples illustrate, the role of enterprise system and technology architects is to create high level blueprints that focus mostly on external interfacing. Engineering these solutions is conducted by systems engineers and designers as part of the Program Design, Acquisition, and Implementation activity.
