Architecture Development Method
Designed to address needs providing:
A set of architecture views
Guidelines on tools for architecture development
A set of recommended deliverables
Links to practical case studies
A method for managing requirements
An iterative process:
over the whole process
between phases
within phases
For each iteration, reconsider:
Scope
Detail
Schedules
Milestones
Consider assets from:
Previous iterations
Marketplace, according to availability, competence and value
Phases
Preliminary: prepare the organization for a successful project
A: Architecture vision
B: Business Architecture
C: Information System architecture
D: Technology Architecture
E: Implementation Planning
F: Migration Plan
G: Implementation Governance
H: Change Management
ADM Guidelines and Techniques
Architecture content framework
Deliverables
Formal Products
Contractually specified
Output from a project
A deliverable can contain many artifacts
Artifacts
Fine grained products that describe an architecture from a specific viewpoint
Classified as:
Catalogs
Matrices
Diagrams
Building Blocks
Components that can be combined with other bb to deliver architectures and solutions
Provides
A comprehensive checklist of outputs
Better integration of work products if adopted across the ent
A detailed open standard for how arch should be described
Content Metamodel
Composed of
Core
Extensions
Formalizes the definition of an Ent Arch
Formalizes the relationship between objects
Enables an EA tool mapping
Entities
Actor
Application component
Business Service
Data Entity
Function
Organization
Role
Technology Component
Enterprise Continuum
Based on architectures and solutions
Models, patterns, arch descriptions
Deliverables produced in this iteration of the ADM
Deliverables produced in other iterations of the ADM
assets from the industry at large
Showing how artifacts evolve
The Architecture Repository is a practical implementation
Stores output from the ADM
Metamodel: describes the arch fw in use within the ent
Architecture Landscape: shows the state of the operating Ent at particular points in time
Strategic Architectures
Segment Architectures
Capability Architectures
Reference Library: contains resuable arch work products
Standards information base
Business
Applications
Data
Technology
Governance Log
Arch Capability: describes roles, skills and responsibilities of the EA practice
Combination of 2 concepts
Architecture continuum
Foundation Architectures
Comon Systems architectures
Industry Architectures
Organizaiton-specific Architectures
Solutions Continuum
Foundation Solutions
Common Systems Solutions
Industry Solutions
Organization-specific Solutions
Provides a common language within the enterprise and between the ent, customers and vendors
