1. Adap%ng the ADM:
Itera%on and Architecture Landscape
Module 5

2. Module Objec%ves
The objec)ves of this module are to describe:
• How to adapt the ADM using the itera%on and
different levels of architecture engagement

3. Itera%on and the ADM
Architecture Capability
iterations support the creation
and evolution of the required
Architecture Capability.
Architecture Development iterations
allow the creation of architecture
content by cycling through Phases B, C
and D
Transition Planning
iterations support the creation
of formal change roadmaps
Architecture Governance
iterations support governance
of change activity

4. Approaches to Architecture Development
• Baseline First
• An assessment of the baseline landscape is used to
iden)fy problem areas and opportuni)es for
improvement
• A suitable approach for when baseline is complex or not
clearly understood
• Target First
• The target solu)on is elaborated in detail and then
mapped back to the baseline
• A suitable approach for when the target state is agreed at
a high level and where the enterprise wishes to effec)vely
transi)on to the target model

5. Baseline First
• Itera)on 1
• Define the Baseline
Architecture
• Itera)on 2
• Define the Target
Architecture and gaps
• Itera)on n
• Refine the Baseline
Architecture, Target
Architecture and gaps

6. Target First
• Itera)on 1
• Define the Target
Architecture
• Itera)on 2
• Define the Baseline
Architecture and gaps
• Itera)on n
• Refine the Baseline
Architecture, Target
Architecture and gaps

7. Transi%on Planning
• Itera)on 1
• Define and agree a set of
improvement opportuni%es,
aligned against a provisional
Transi)on Architecture
• Itera)on n
• Agree the Transi%on
Architecture, refining the
iden)fied improvement
opportuni)es to fit

8. Applying the ADM Across the Architecture Landscape
Strategic Architecture provides an organizing
framework for operational and change activity
and allows for direction setting at an executive
level
Segment Architecture provides an organizing
framework for operational and change activity
and allows for direction setting and the
development of effective architecture roadmaps
at a program or portfolio level
Capability Architecture provides a framework
for operational and change activity and the
development of effective architecture roadmaps
realizing capability increments project level
