Model-Based Systems Engineering with GENESYS

Integrated and Federated Architectures

• An integrated architecture: • Exhibits concordance across all Operational, Systems and Technical viewpoints, meaning: • the architectural objects common to more than one view are identical or linked via underlying data relationships • all objects that have relationships across views are linked via underlying data relationships • A federated architecture: • A distributed strategic information asset base ( of independent architectures ) • A framework for enterprise architecture development

• Recognizes the uniqueness and specific purpose of disparate architectures and allows for their autonomy and local governance while enabling the enterprise to benefit from their content

Terminology Confusion: DoDAF 2.0 “Model” ≠ MBSE “Model” Visualizing architectural data is accomplished through models (e.g., the products described in previous versions of DoDAF). Models (which can be documents, spreadsheets, dashboards, or other graphical representations) serve as a template for organizing and displaying data in a more easily understood format. • Models attempt to represent the entities of the engineering problem (opportunities) and their relationships to each other and connect them to the proposed solution • MBSE creates an integrated system model which brings insight into the structure, integrity and sufficiency of the ultimate solution DoDAF 2.0, Volume 1 (2009)

Graphical and textual views derived from the true (under lying) systems model are at most viewable projections of the model.
