The document discusses enterprise architecture frameworks. It provides an overview of John Zachman's enterprise architecture framework, which structures architecture representations across six rows representing different stakeholder perspectives and six columns representing different aspects of the enterprise. The framework helps organizations design, select, and build architectures by providing a tool for evaluating different architecture options and ensuring they are aligned with business goals. It also briefly mentions The Open Group Architecture Framework (TOGAF) as another example of an enterprise architecture framework.

5. WHAT IS ENTERPRISE
ARCHITECTURE ?
• The concept of enterprise architecture was discovered in 1978
by IT and Business Consultant John Zachman, who published
his popular article in “IBM journal”, Its title was "A framework
for Information Technology Architecture "(Hermans, 2015).
• Systems Development Life Cycle (SDLC).

7. ENTERPRISE ARCHITECTURE DEFINITIONS
• Enterprise Architecture (EA) defines the current and desirable
future states of an organization's processes, capabilities,
application systems, data, and IT infrastructure and provides a
roadmap for achieving this target from the current state (Ross
et al., 2006; Tamm et al., 2011; Zachman, 1987).
• EA has been traditionally conceptualized as a collection of
artefacts that represent an organization's business systems and
IT systems, together with a planning process for documenting
these systems (Ross et al., 2006).
• EA includes details about an organization's processes,
capabilities, data, application systems and IT infrastructure
using a variety of standardized representation techniques
(Kaisler et al., 2005; Lankhorst, 2013).

8. ENTERPRISE ARCHITECTURE DEFINITIONS
• The Open Group definition : Enterprise Architecture is about
understanding all of the different components that go to make
up the enterprise and how those components inter-relate.
• Wikipedia :Enterprise Architecture is the practice of applying a
comprehensive and rigorous method for describing a current
and/or future structure and behavior for an organization's
processes, (information) systems, personnel and organizational
sub-units, so that they align with the organization's core goals
and strategic direction. Although often associated strictly with
information technology, it relates more broadly to the practice
of business optimization in that it addresses business
architecture, performance management, organizational
structure and process architecture as well.

9. Enterprise architecture is a complete expression
of the enterprise; a master plan which “acts as a
collaboration force” between aspects of business
planning such as goals, visions, strategies and
governance principles; aspects of business
operations such as business terms, organization
structures, processes and data; aspects of
automation such as information systems and
databases; and the enabling technological
infrastructure of the business such as computers,

11. ENTERPRISE ARCHITECTURE TYPES
• Business architecture: business process,
organization, people.
• Information system architectures
• Data or information architecture: data and Information
• Application architecture: Services
• Technology architecture: hardware, software,
network.

13. When we use Enterprise
architecture.
System complexity—Organizations were
spending more and more money building IT
systems.
Poor business alignment—Organizations
were finding it more and more difficult to
keep those increasingly expensive IT
systems aligned with business need.

17. ENTERPRISE ARCHITECTURE
Business architecture that
defines the organisation
Infrastructure that supports the IS
What to do, Where to do it, and
How to do it?
Applications and information
Business
Technology
Information
Systems
Strategy
The Enterprise Architecture discipline defines and
maintains the architecture models, governance, and
transition initiatives needed to effectively co-ordinate
semi-autonomous groups towards common
business and IT goals

18. ENTERPRISE ARCHITECTURE
Business
Technology
Information
Systems
Strategy
Documentation of organisation capabilities,
resources, product portfolio, external interfaces,
high-level business process blueprint that
supports the strategy
Infrastructure that supports the IS:
- Technical components: servers, networks, etc.
- Technology: platforms, etc.
Applications and information that support the
business and implement the business functions in
the IT systems
Assets that define the enterprise
strategy, goals and objectives.
What to do, and how to do it?

21. ENTERPRISE ARCHITECTURE FRAMEWORKS
• An architectural framework is a tool for:
• Designing a broad range of a architectures.
• Assisting the evaluation of different architectures.
• Selecting and building the right architecture for an
organization.
