Design & Delivery Strategy
Build strong foundations: Agility
depends on strong foundations; we can
never be agile, if we keep spending time
in fixing the core or Architectural
building blocks.
Establish Implementation
strategy: Implementation strategy to
be aligned to the Architecture vision and
communicated to the Agile team to
ensure alignment to the vision.
Adopt a layered
structure: Create layered views from
business capabilities, process,
application through to data.
Design to scale: Separate the core
capabilities from the business services
loosely couple components and apply
abstraction for growth and scalability
with minimal technical debt

The Architecture Roadmap is Key
• Must be adaptable and high level
• Determine the scope of upfront design by
through crawl-walk-run approach :-
• Identifying foundational building
blocks
• Assess business benefit and
criticality
• Just enough anticipation by :-
• Dependency Assessment
• Minimising the technical debt

Agile architects need to work in a different way

How to go about delivering an agile architecture
1. Design emerges. Architecture is a collaboration.
2. The bigger the system, the longer the runway.
3. Build the simplest architecture that can possibly work.
4. When in doubt, code or model it out.
5. They build it. They test it.
6. There is no monopoly on innovation.
7. Implement architectural flow.

Follow the principles of Agile Architecture

• Capgemini globally is beginning to consolidate frameworks and tools to help architects
work in agile environments
Key elements of framework
Capgemini Agile Architecture Framework
What does your architecture
need to deliver
How will you go about delivering
your architecture

Architecture Roadmap

Planning Toolkit
When do you need to produce
architecture deliverables

• Outlines a framework of content needed to define
and deliver the minimum viable architecture
• Allows the architecture to support the production of
the MVP
• Keep Simple at First and delay major design
decisions
• Supports Evolutionary architecture
• Build for Day 1 Non Functional Requirements, but
understand
• Looks to embrace industry wide approaches such as
domain driven design

An aspirational statement of
where the organization or
business unit would like to be
in near-term or long-term
A method, approach or plan of
action to achieve desired goal
of a common information
system.
Defines “What” a business
does”. Technology capability
road mapping is structuring
the functional scope of
capabilities w.r.t business
expectations and maturity
Translation of sub-capabilities
to features to provide service-
level context to validate
strategic technical capabilities
requirements and articulation
of dependency
Traceability of requirements to
articulate desired level of

• Outlined by Eric Evans in the book, Domain-
Driven Design: Tackling Complexity in the Heart
of Software
• An an approach to software development that
looks to connect the implementation to an
evolving domain model
• Focuses on collaboration between technical and
domain experts to refine a model to address
domain problems
• Introduces ubiquitous language and can improve
communications between business and technical
stakeholders
• Can increase flexibility of solution and supports
agility
Key elements of Agile Architecture Toolkit
Domain Driven Design

• The TOGAF ADM can be tailored and adapted
to support an agile delivery
• The ADM lends itself to iterative delivery in
line with agile delivery
Tailored TOGAF’s ADM framework
• Capgemini has been exploring alignment of
TOGAF ADM with Scaled Agile Framework
(SAFE) – aligning PI with TOGAF ADM

• Understanding the appetite for the
organization to be responsive can aid
planning and governance
• Enables an architect to identify key
stakeholders and their behaviors to help
shape the architecture roadmap
accordingly
• Allows the architect to assess their
context against a number of criteria to
understand the degree of agility of an
organization

Agile Spectrum Assessment – Planning Tool

Architecture is more relevant than ever in
an agile environment but the role needs
to evolve to remain relevant
Agile architecture represents a shift in
thinking and a different mindset
It’s about leading people, facilitating
collaboration and driving emergent
solutions
