Making Enterprise Architecture (EA)
Strategic with Business and Information
Sohel Aziz, Infosys Technologies
Today, enterprises need to handle a variety of internal
and external drivers...
Enterprises are driven by ...and they react in many
macro-trends like... ways, for example...
Globalization of the market place Reduced vertical integration and
– Emerging economies are global distribution of workforce
attractice markets, but they – Decomposition of the value chain
require operations in a variety of also in services industries, e.g.
geographies, cultures and financial services
legislations – Networked value creation
Increasing competition Restructurings, Mergers &
– Markets become more Acquisitions
transparent through information – Leverage synergies
availability – Get access to markets
Demand for Responsibility Faster innovation cycles
– Increasing regulation and – Agility is a given to maintain margins
sensitivities of both capital
markets and public opinion Standardization, automation and
require better control decomposition of the value chain
...to help organizations in this environment, EA has to
expand its scope

The Enterprise Architecture is the organizing logic for business
processes and IT infrastructure, reflecting the integration and
standardization requirements of the company‘s operating model.

of top and bottom line can be addressed

Technology standards are still main deliverables – but
information and business are becoming more important
Business Architecture is increasing in importance –
although the technical focus is still strong.
Integration and information integrity are core objectives,
driven by focus on SOA and Data Architecture
EA is becoming strategic at the corporate level...

Furthermore, EA needs to be able to drive multiple,
interrelated streams of change across multiple domains

EA, as a discipline, will need to face a broader set
• What is the scope of "Architecture" in "Enterprise Architecture" really mean? 3
of 4 architectures in most EA activities are IT related the one or the other way.
• What does the term “Business Architecture" mean? Three sets of models for
IT, one for the whole rest of the organization? Is that right?
• Creating organizational capabilities involves many integration of people,
process information and technology. Can that be driven by IT?
• The structured, architectural approach has worked well within the realm of IT.
How can it be applied to other areas or the whole of the enterprise? Can we
"architect" an organization?
• Can Enterprise Architecture become a tool for transforming the organization?
And should it be?
• What will the role of IT be in the future?
This implies changes to how we deliver EA
• It is not possible to enumerate all domains required to describe the various
parts of architecture
– The framework must be flexible and extensible, while organizing the
interfaces between the architectures
• Manage change of multiple architectures simultaneously
– No linear order of activities leading to need for effective transformation
• Issue driven approach of business consulting will need to be married with
structure, top-down approach of Enterprise Architecture
– The link between strategy and execution will be key
• Focus on business process and information instead of application packages
and technology, that will drive
– Service Oriented Composite Application Architecture
– Dynamic, Pervasive Infrastructure
Going forward, Enterprise Architects need to build
business capabilities and increase architectural maturity
• Enterprise Architects’ responsibilities are growing:
– More to do! Maintaining the technology architecture must be made easy
on resources to be able to expand EA’s scope
• Architects need to build credibility throughout the organization
– This needs to manifest in their impact and acceptance within the
organization (especially the business)
– Measuring architectural maturity through a metrics program is best
• As Enterprise Architecture starts rearranging the elements of business,
architecture teams need to understand the dynamics of a business
– by building skills among existing architecture teams
– by attracting strategic thinkers from non-IT and corporate level
