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 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.
SSC Key EA Artifacts Diagram
Enterprise Architecture
Enterprise Architecture (EA) includes and is broken down into Strategic and Solution Architecture.
Video overview of EA, Strategic and Solution architecture artifacts
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
Prepared by: Benefits Management.
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.
Scope/Constraints: None beyond the constraints of the default ArchiMate 3.0 recommended viewpoint.
Key Stakeholders: Enterprise architects, business analysts, strategic planning, benefits realization, SSC executives.

Business Capability Map
Purpose/Value: A primary communication mechanism with SSC executives on the state of the architecture, activities, and progress towards desired target direction. Helps ensure alignment between current/target activities and the strategic direction/capabilities of the organization. Investment prioritization.
Prepared by: Enterprise Architecture - Business Capability Lead
Scope/Constraints: Generally limited to identifying capabilities/sub-capabilities, and their association with enterprise strategic outcomes, goals, drivers.
Key Stakeholders: Senior executives, branches, business managers, enterprise and business architects. Investment prioritization.

Segment Diagram
Prepared by: Enterprise Architect - Segment Architect/Lead
Purpose/Value: Enables EA to organize, prioritize and assign architecture work/activities. In particular, it identifies the segments that will be used to organize EA work, and distributes the key services/functions among them. Every identified SSC service should belong to a segment.
Scope/Constraints: Uses only business roles, business actors, and business functions with categories "SSC Segment", "SSC Client-facing Service", and "SSC Supporting Service". It may begin to associate key high-level roles, information, applications - but generally, it leaves details of architecture to dedicated lower-level diagrams. One diagram per defined segment.
Key Stakeholders: Enterprise architects/Enterprise Architecture management/executives.

Strategic Service Diagram
Prepared by: Enterprise Architect (in collaboration with Service Leads/Architects)
Purpose/Value: Provides a conceptual view of SSC Services, key inter-service linkages, strategic linkages, and links to enabling technologies. Answers the questions: 1) What services/functions need which services to operate?, 2) What technologies are required by a particular SSC Service?
Scope/Constraints: This diagram defines, at a high level, an SSC service. It links the SSC Service to Business Capabilities (1 or more), and to other key business functions/services, and to the key foundational/supporting technologies. The diagram may expose some of the key sub-functions/processes that are performed in that SSC service (down 1 level of conception). Detailed business, application, information and technology diagrams for a particular service are to be detailed in other (solution-level) diagrams.
Key Stakeholders: Enterprise architects/Enterprise Architecture management/executives, Service architects.

Architecture Roadmap Diagram
Prepared by: Enterprise Architect (in collaboration with Service Leads/Architects)
Purpose/Value: Defines/describes the different architectures for a particular service in defined states (n-2, n-1, n, n+1, n+2) and plateaus (current, target, target+), and what work packages (projects) will satisfy which identified architecture gaps.
Scope/constraints: Uses Implementation and Migration elements, and Motivation elements (goal/outcome).
Key Stakeholders: Enterprise Architects, Service Architects, Solution Architects, Service leads/teams.

Solution (including Service) Architecture
These diagrams are for service or solution architectures for initiatives. The solution architecture artifacts are usually captured in a Service and Solution Architecture Description deliverable (package). These solution architectures are reviewed with enterprise architecture through a governance processes (architecture assurance) to help ensure alignment with the enterprise architecture.
Conceptual Solution Architecture
The conceptual solution architecture is a subset of a complete solution architecture. It identifies the requirements, benefits and measures of success for a project, strategic goals/outcomes and business capabilities to be realized in the solution/initiative. Further, it identifies the key business functions (SSC services) that will be used, created, impacted by the effort, and begins to outline the scope of the initiative.
Requirements Diagram
Prepared by: Solution architect, service architect.
Purpose/Value: List and definitions of the requirements for a project/initiative, as well as any related/influencing standards, principles, policies and/or reference architectures.
Key Stakeholders: Project managers, project teams, business analyst, business architects, service architects, solution architects, engineers.
Based on ArchiMate Viewpoint: Motivation Viewpoint
Benefits Dependency Map
Prepared by: Benefits management (in cooperation with the project/service team and/or service/solution architect)
Purpose/Value: Identify the benefits of a projects/initiative, identifying key performance metrics (KPI's) that will be used to measure success of the effort. Helps ensure alignment with enterprise outcomes, identify and link requirements to tactical and strategic outcomes.
Scope/Constraints: Uses motivation elements of outcomes and implementation & migration element of work package and deliverable.
Key Stakeholders: Project manager/lead, project team, business analyst, benefits realization team, governance bodies, management, executives.

Context Diagram
Prepared by: Service/Solution architect
Purpose/Value: Identifies the services used and/or modified/created by the initiative. Identifies and links the initiative to a business capability to be fully or partly realized by the initiative.
Key Stakeholders: Enterprise Architect, Governance Bodies (EART, AC, SARB).
Context Diagram guidance and example video
Conceptual Diagram
Prepared by: Service/Solution architect
Purpose/Value: Identifies what, at a high/conceptual level, this project/initiative intends to do (key/main functions), for which clients (roles/actors), and what key information will be required/managed.
Scope/Constraints: Show no sequence/flow, and generally no associations. Limited to actors, roles, business functions (key high-level), business information, key application components, system software, technology services.
Key Stakeholders: Governance bodies (particularly AC and ESSARB), project teams/leads/managers, executives, enterprise architects, service architects, solution architects.
