Here are some matrices and such that portray some of my representations of various "architectures".

2. Enterprise Management Architecture - Structural Decomposition
|
Configuration Management Process
(Providing a Continuum of Enterprise Knowledge and Governance) |
Activities |
Roles
(Architects work with Types of things, Engineers work with Specifications of things) |
| Configuration Change Management |
Work from the “Enterprise as object” perspective. Enterprise Management (e.g., implementation governance and operations of functional capability) |
Business Architect |
| •Technology Insertion |
|
Enterprise Engineering can use “system engineering” techniques and tools if you remember that “people” are the primary component of the enterprise system. |
(e.g., Enterprise Architect, Management Analyst, Semantic Analyst, Intelligence Analyst) |
| •Product/Service Test and Evaluation |
|
Enterprise Architecture (i.e., endeavor ontology and knowledge base) (e.g., Continuity Communications Architecture as “CC function’s architecture” within and across larger enterprise architecture). Provides a database linking Requirements (PRM) to Resources (DRM and TRM) to Processes (SRM) to Functions (BRM) to Organization Units to Organizations to Locations. |
|
| •Governance of Implementation |
|
|
Strategic Management (Missions, Visions, Goals, Objectives (i.e., Performance Measures), and Implementation Strategies (i.e., Portfolios of Programs of Projects)) |
|
| |
|
|
|
IT Portfolio (e.g., New IT Investments, Recurring IT Operations, IT Operational Improvements) |
|

Infrastructure Engineering (e.g., Networks, Network Security) |
