Agility is not just the ability to change. It is a cultivated capability that enables an organization to respond in a timely, effective, and sustainable way when changing circumstances require it.
The aim of an EA must be to define, implement and refine the
overall architecture on a continuous basis. However, most of today’s EA is
static and theoretic. The biggest problem with EA is not the tools, nor the frameworks
(although they certainly contribute), but
with the concept itself, and the means used to express the needs, desires, and
requirements of the organizations' thoughts, direction, goals, and
objectives. While emerging technology trend such as SMAC (Social/Mobile/Analytics/Cloud)
brings both unprecedented opportunities and potential risks in shaping business today, Agile
business needs Agile Architecture, static enterprise architecture frameworks have to give way to continuous business transformation best practices. And EA plays a critical role in orchestrating such transformation. But, what’re the new
characteristics of Agile EA?
1. Agile EA
What Is Agility?
According to industry experts: Agility is not just the ability to change. It is
a cultivated capability that enables an organization to respond in a timely,
effective, and sustainable way when changing circumstances require it. The
management literature increasingly refers to this ability as a “dynamic
capability”: the potential to sense opportunities and threats, solve problems,
and change the firm’s resource base. That said, your environment 'will' change, so anything that
you do too far "upfront" is likely to be wrong in the future. The
agile practices address this using a short feedback loop (plan, try, test,
learn); so that you never get too far away out on a tangent on the manifold of
reality. From the EA perspective, it’s about how to keep the modular design,
continue planning and improving, and then fulfill EA's purpose--to bridge
strategy and execution, transcend business into the next level.
The Ten Characteristics of Agile EA
EA practice should guide enterprise change according to a business strategy, and that great
organizations develop a strategy based on a vision of the future, and that
today’s world is very complex due to the rate of change and its disruptive force,
agility in how organizations execute their strategy is necessary.
- Agile Enterprise Architecture is not a blueprint.
- Agile EA is a highlight which changes to focus on, which one can be ignored
- Agile EA is about impactful choices upfront that will make later choices easy.
- Agile EA is about the stable ground, but not frozen (static) ground.
- Agile EA emerges over time, incrementally think about the future, but doesn't overbuild the architecture.
- Agile EA is to be open about your architecture — encourage criticism, allow requirements to drive your architecture updates.
- Agile EA embraces Business ecosystem (as both functional and organizational borders are blurred)
- Agile EA weaves Various Factors: Both hard factors (organizational structure, technology., etc) and soft elements (culture, leadership) seamlessly
- Agile EA supports many Agile Wings such as Agile strategy, agile culture, agile PM methodology, agile budgeting, agile governance. etc.
- Agile EA Fits for Purpose and Mind the Gaps.
EA is a planning
function: Spelling it out a little more, the first step would give enterprise
architects cause to describe and agree on the current purpose of doing EA, and to
explore the changes in the marketplace which might demand that architects do EA
differently. From there, EA could explore which capabilities remain "fit
for purpose" and where there might be gaps or inadequacies in EA methodology/toolkit for the future -
thereby, enabling architects to take a "structured" approach.
For example, Agile EA manifests Agile Adoption Challenges:
For example, Agile EA manifests Agile Adoption Challenges:
- Agile adoption requires a major shift in the mindset and culture of an organization.
- Agile adoption is not restricted to only IT projects.
- Agile approach originated in the context of IT projects can be scaled to suit the enterprise architecture discipline.
- Agile in only the IT project area and not Agile in other areas such as enterprise architecture could be problematic and risky.
- Agile adoption would require balancing agility across the board.
2. What Agile Methodology Brings to EA
How many enterprise architects consider architecture a
well-structured problem? Those that do may tend to apply traditional thinking
in search of the “right” solutions. Perhaps it is an ill-structured problem
with social implications within an organization and lends itself to more
creative thinking in search of a “better” solution. After all, with today’s
rate of change, how long will the “right” solution remain “right”? If agile were applied in EA, what would the
agile methodology bring to EA? Agile
is very good at transparency, and, if done right, it helps elicit requirements
that the original planners do not anticipate.
Is Agile methodology
good for architecture development? Does it make sense to adopt agile while developing architecture or iterative model still makes sense? Agile and Scrum methodology is gaining
grown these days. Agile shouldn't be inherently restricted to software
development. In a great many instances, businesses are very poor at defining
their ideal target state, or can only do so in very generalized ways. In these
instances, agile techniques are very
beneficial as methodologies which focus on evolution and adaptation, and are
responsive to change, can provide the best outcomes. The essential of Agile methodology is iterative communication,
cross-functional collaboration and improving customer satisfaction, such a mindset shift is indeed essential in Agile EA Artifacts:
The circular vision, goals, and objectives of the leadership;
The dynamic structure required to execute that vision and strategy;
The distinct core capabilities needed, either in the present organization, or those that must be created or secured from other sources;
The major agile processes to be executed using those capabilities;
The kinds of the latest technology and other resources needed to bind the capabilities into executable processes.

Agile Principles:
If apply the agile mindset to architecture development, whether it’s EA or one
of the architectural domains, the principles include:
- Bottom Up Approach need well balance out with Top-down Architecture Foundation;
- People over Process, high mature team is the key Success factor for Agile
- Agile is not lack of discipline, but need stronger architecture and management discipline;
- Agile is both methodology and mindset, it means better communication, adaptability and customer satisfaction.
- Agile is not just about speed, also means high quality
Scaled Agile Framework (SAF): It’s a good way to deploy agile and opportunistic architecture planning that informs the
work/stories for the Agile development teams. Climb to the desired level of
maturity with SAF in keeping the enterprise focused on the desired future state
through "Architecture Epic Planning" and developing sequenced
"Architecture Runways" across the enterprise portfolio, EA will be
able to guide executives towards fact-based decisions around managing
investments and/or risk.
Agile philosophy warns organizations to not attempt “big
design up front” because doing so may result in teams scrapping a major chunk
of hard work if the business decides to change its approach. And Agile is
transforming from a software development methodology into an overarching
philosophy to include agile mindset, agile consensus, agile architecture, and
even Agile movement, to balance agility and discipline, to embrace hyper-connectivity
and hyper-digitalization.

You've described the what, not the how.
Nice thoughts. I believe the EA frameworks like TOGAF and Zachman model, like any other well built frameworks, are inherently adaptive and flexible enough to align with the Agile approach chosen by an enterprise.
Here is a small write-up on how one could align EA with the agile processes.
Align Agile SDLC with Zachman Model.

I hope this help.
AgileEA is already taken, google it.
