ENTERPRISE
• "Enterprise" is an entity defined and organized
to create value
• The value creation is structured to be
composed of product, services, people,
location, performance, function, process,
data, application, technology, infrastructure
and providers.

ARCHITECTURE
• Speaks of drawn model to describe
the holistic and particular view of the
system in actualizing the “value”
defined for the organization.
• Blueprint which define the baseline of
common and differentiated
information on how the system is
organized and expected to behave to
actualize the mandate, mission,
principles, vision, goals, objectives
and performance.

Need for Enterprise Architecture

VALUE OF ENTERPRISE ARCHITECTURE
“You are going to do
architecture, because without
architecture, you cannot do
any of these things:
• Alignment
• Integration
• Change
• Reduced Time-to-Market
-John Zachman
Enterprise Architecture Framework

ALIGNMENT
• Enterprise architecture provides the
framework to enable better alignment of
business and information technology
objectives. The architecture used can also
serve as a communication tool.

INTEGRATION
• Enterprise architecture establishes the
infrastructure that enables business rules to
be consistently applied across the
organization, documents data flows, uses and
interfaces.

VALUE CREATION
• Enterprise architecture provides better
measurement of information technology
economic value in an environment
where there is a higher potential for
reusable hardware and software assets

CHANGE MANAGEMENT
• Enterprise architecture establishes consistent
infrastructure and formalizing the
management of the infrastructure and
information assets better enables an
organization-wide change management
process to be established to handle
information technology changes

COMPLIANCE
• Enterprise architecture provides the artifacts
necessary to ensure legal and regulatory
compliance for the technical infrastructure
and environment.

What it means
to secure information…
1. Establish the governance and
management organization of
information security that
comply to best practice
standards.

What it means
2. Identify the information
assets, and perform the
assessment of vulnerabilities
and threats that surround
the creation, storage, use
and sharing of information.

What it means
3. Develop, document and
implement policies, standards,
procedures, and guidelines that
ensure confidentiality, integrity,
and availability in the person,
process, data, application and
infrastructure of information.

What it means
4. Evaluate, acquire and use
security management tools to
classify data and risk, to audit
information system, to assess
and analyze risks in the solution
development and infrastructure,
to monitor and control areas of
vulnerabilities. and implement
security controls and appropriate
reactive responses to threats.

CHANGE…
1. We can only evaluate that which
is measurable
2. We can only test that which is
agreed.
3. We can only improve that which
is actualized.
4. We can only change that which
is established.
