===== Segment/Service Overview Diagram =====
+
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.

Scope/Constraints:  Uses only business functions, and business functions with categories "SSC Segment", "SSC Client-facing Service", and "SSC Supporting Service".  It does not show detailed information about roles, processes, information, technologies, applications involved in each segment.  One diagram shows all segments, and key high-level associated functions.

Key Stakeholders:  Enterprise architects/Enterprise Architecture management/executives.
  −
 
  −
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.  Segment diagrams are produced for each segment that provides a more complete definition of what belongs in each segment.

Scope/Constraints:  A template is provided to complete the diagram.  This particular diagram links the SSC Service to Business Capabilities (1 or more), and to other key business functions/services, and to the key foundational/supporting technologies.  Similar to the Conceptual Foundation Technology diagrams, except the focus here is on the business function and clients, rather than the technologies.  The diagram may expose some of the key sub-functions/processes that are performed in that SSC service.

  −
Key Stakeholders:  Enterprise architects/Enterprise Architecture management/executives.
  −
 
  −
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 an SSC Service?

Scope/ConstraintsThis 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.

     −
Scope/Constraints: Link any Business Function or Business Process to a capability.  
+
Key Stakeholders:  Enterprise architects/Enterprise Architecture management/executives, Service architects.
   −
Key StakeholdersEnterprise architects, segment architects, strategic planning.  
+
Purpose/ValueProvides 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?
   −
Purpose/Value:  To link between strategy and enterprise architecture (core elements). Used for mapping key core elements of architecture to realized capabilities.  In particular, those supporting functions/services and related applications/technology in support of particular capabilities.

===== SSC Service Catalog =====
+
Scope/constraints:  Uses Implementation and Migration elements, and Motivation elements (goal/outcome).
   −
Key Stakeholders:  SSC executives, service mangement, service inventory, enterprise architects, service leads, service teams, service architects, solution architects.
+
Key Stakeholders:  Enterprise Architects, Service Architects, Solution Architects, Service leads/teams.
   −
Purpose/Value:  Provides a list of the SSC functions designated as "SSC Services" including with key attributes used for service management and service inventory management.
+
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.
