Basic Architecture Development Model (ADM)

Question 1

Four characteristic of Architecture Development Model

Answer 1

An iterative method, over the whole process, between phases and within
phases.
Each iteration = new decisions:
-Enterprise coverage
-Level of detail
-Time horizon
Architecture asset re‐use:
-previous ADM iterations
-other frameworks, system models,
-industry models,…
Decisions based on:
Competence / resource availability
-Value accruing to the enterprise.

Every phase is validated against and validates
the current requirements of the business.

Question 2

Answer 2

1. ## PreliminaryA. Architecture Vison
   —————————————————–
   B. Business Architecture
   C. Information Systems Architecture
   D. Technology Architectures
   ——————————————————
   E. Opportunities and Solutions
   F. Migration Planning
   ——————————————————
   G. Implementation Governance
   H. Architecture Change Management
   ——————————————————-
2. Requirements Management

Question 3

Preliminary Phase activities

Answer 3

• Instigates the ADM
• Setup the Team
• Setup Governance and oversight
• Create: REQUEST FOR ARCHITECTURE WORK

Question 4

Architecture Vision activities

Answer 4

Initiates a ADM cycle
- Takes the REQUEST FOR ARCHITECTURE WORK and identifies HOW this will be accomplished (ARCHITECTURE VISION)
- PLANS the work cycle
- Performs STAKEHOLDER ENGAGEMENT
- Assess CAPABILITY of the Enterprise to do the work and accept the change

• Create: STATEMENT OF ARCHITECTURE WORK

Question 5

B, C, & D: Detailed Architectures activities

Answer 5

B. Business Architecture
C. Information Systems Architecture
D. Technology Architecture

The ARCHITECTURE VISION (the high level
description of the GAP that needs to be
addressed) is LOOKED AT in more detail across
the four domains
– B: Business
– C: Application & Data
– D: Technology

Question 6

E & F: Planning the change activities

Answer 6

E. Opportunities and Solutions
F. Migration Planning

E & F concern themselves with HOW the
GAPS identified in B, C & D are to be
addressed
1. Identifies SOLUTIONS and creates the
ROADMAP and the IMPLEMENTATON AND MIGRATION PLAN
2. Liaises with PROGRAM MANAGEMENT TEAM
who will perform the implementation

Question 7

G & H: Controlling the work activities

Answer 7

G. Implementation Governance
H. Architecture Change Management

The delivery projects are underway but the
EA still needs to keep an eye on them (MONITORING)
1. Issue ARCHITECTURE CONTRACTS (to define
and start the projects)
2. Audit the projects
3. Manage CHANGE REQUESTS and other issues

Question 8

Requirements Management activities

Answer 8

Requirements central to the ADM
Requirements Management:
– stores REQUIREMENTS
– Feeds them into the other phases as
necessary (where they can be modified,
added to or removed)
– Collects them up at the end of the phase
