| − | In addition to a content metamodel, SSC has established a set of specific artifacts (catalogs, matrices, diagrams) that are required. In general, these artifacts follow the recommended viewpoints established in the [https://pubs.opengroup.org/architecture/archimate3-doc/ ArchiMate 3.0.1 Specification]. However, in some instances we have chosen diagrams that better suit our particular needs, particularly in respect to project and service governance. The following are the required and recommended artifacts for architecture at SSC.

| − | | |
| − | === Strategic Architecture ===
| |
| − | This portion of enterprise architecture contains artifacts that define the scope of the enterprise, break it down into useful portions (segments), describe the strategic current/target states, drivers and motivations.
| |
| − | | |
| − | ==== Strategic Motivation Diagram ====
| |
| − | Based on ArchiMate Viewpoint: [https://pubs.opengroup.org/architecture/archimate3-doc/apdxc.html#_Toc489946175 Motivation Viewpoint]

| − | Scope/Constraints: None.
| |
| − | | |
| − | Key Stakeholders: Enterprise architects, business analysts, strategic planning, benefits realization, SSC executives.
| |
| − | | |
| − | Purpose/Value: Used to identify and related the strategic drivers, goals, outcomes of the organization, and the key strategic stakeholders. Provides links to identify what existing and planned architecture are supporting the enterprise's desired target direction. All solution architectures should link (directly or indirectly) to a strategic goal or outcome.
