Enterprise Continuum and Tools
Meaning
Continuum
:pencil2: A continuous extent of something
:pencil2: No part of which is different from any other
Based on the concept of
:fire: Most Abstract to Most Specific
:fire: Bi-Directional relationship between Architectures
Left to Right - Enterprise needs and business requirements increase in detail
Right to Left - Leverage Architectural components and building blocks
Overview
Model for structuring virtual repository
Method of classifying architecture and solution artifacts
:star:
Architecture Repository
- result of practical implementation of Enterprise Continuum
:fire: Consists of architectures and solutions assets like :
Models, patterns and architecture descriptions
Deliverable produced in phases or ADM
Show how artifacts evolve
A combination of
Architecture Continuum
Solution Continuum
Enable effective use of COTS (Commercial-Of-The-Shelf) products
Promotes reusable architecture and solution assets
Architecture
Continuum
Types
Common Systems Architectures
Example : III-RM
Industry-Specific Architectures
Example : ARTS, POSC
Organization-Specific Architectures
Foundation Architectures
Example : TRM
Information
:fire: Represents progression occurring at several levels
Logical to Physical
Horizontal (Technology focused) to Vertical (Business focused)
Generalization to Specialization
Taxonomy to Architecture Specification
Most Generic is Foundation Architectures
Most Specific is Org specific Architectures
Solutions
Continuum
Types
Foundation Solutions
Common Systems Solutions
Industry-Specific Solutions
Organization-Specific Solutions
Information
Entire transition spectrum (Foundation to Org-Specific) is important for balancing cost and value
Matches exactly at the same architecture level as in Architecture Continuum
Forms a "Solutions Inventory / Reuse Library" adding significant value to managing and implementing improvements to IT environment
Relationships
:fire: Both Continuum (s) are related by
Guidance
Direction
Support
Example : Foundation Architecture
Consists of building blocks and corresponding standards
Supports all Common systems archs and hence complete enterprise operating environment
Contains complete and WIP solutions
Is a
Framework-within-framework
Has few internal assets, at first
Grows by adding reusable building blocks
Tools
:fire: Are needed to manage/control artifacts with EC
To promote re-use
To enable sharing of arch info with org
for easier arch maintenance
to use common terminology
to provide stake holders with relevant models
