Enterprise architecture Definition
Enterprise architecture is the process of translating
business vision and strategy into effective enterprise
change by creating, communicating and improving the
key principles and models that describe the
enterprise's future state and enable its evolution.
The scope of the enterprise architecture includes the
people, processes, information and technology of the
enterprise, and their relationships to one another and
to the external environment.
Enterprise architects compose holistic solutions that
address the business challenges of the enterprise and
support the governance needed to implement them.

4. The Need of Architecture
The Winchester House, San Jose, California
• 38 years of construction – 147
builders 0 architects
• 160 rooms – 40 bedrooms, 6
kitchens, 2 basements, 950 doors
• 65 doors to blank walls, 13
staircases abandoned, 24 skylights
in floors
• No architectural blueprint exists
5. • Use helicopter to see the “problem” mountain that needs to be climbed
• Use the helicopter to land on the mountain that needs climbing
• Lead the team that trek through the jungle of confusion to the mountain and climb it because this is
a guided journey not an expedition
Role of an Architect – Climbing The Right Mountain
Not all problem mountains are easy to pick
out of their surroundings

8. Enterprise Architecture Analogy: The OODA Loop
The OODA Loop was originated by U.S. Air Force Colonel John Boyd, who developed it to define a way to understand how
fighter pilots, often in inferior aircraft, consistently won air combat engagements against enemy pilots. What Boyd observed was
that winning pilots acted more quickly than their less successful opponents by cycling rapidly through four states:
•Observe — See the situation and adversary.
•Orient — Size up the vulnerabilities and opportunities.
•Decide — Determine which combat maneuver to take.
•Act — Execute the maneuver.
9. Although modern vision talk
about governance models,
iterative approaches and
focus on value and business
case, however …
There is only one way and
that is the top-down
approach
• Observe : business contect
• Orient : define future state
• Decide : create the plan
• Act : Execute the plan
EA : The Multi Year Plan
10. Link to Business Strategic Planning and
Budget Process
“In a well-architected enterprise, EA is the
coordinating process that helps guide the
strategic and management processes of the
enterprise to be in sync with respect to
evolving toward a future state vision.”
“EA efforts must continually be revisited and
updated to reflect the current business.”

12. Alice stands at a crossroads and asks the cat
which path she should take.
He asks “Where are you going?”
She says she doesn’t know.
“Well then, it doesn’t really matter which path
you take.”
The meaning of the painting is indicated by the
title La Clairvoyance (perspicacity). The egg will
become a bird. The artist sees what it will
become. Through understanding the artist
knows that the egg will become a bird.
