and to the environment, and the principles guiding its design and evolution. (IEEE 1471-2000)
● Solution Architecture
It is an overall Technical Architecture that can be reflecting different elements of technology within the
enterprise. Its scope can be data, software, application or any IT Infrastructure technical components
● Architecture Framework
A resource that guides the development or description of an architecture
● Business Architecture
A perspective of the overall architecture reflecting enterprise mission, strategies, goals, business drivers,

Architecture Vs. Design
Example: System Architecture & System Design
! Design: How each component should be built
! Many different designs may address the same need
! Different Architectures imply different needs
! Analogy:
! House:
! Architecture:Number of rooms, main
structure, character, guiding lines.
! Design: Interior Design, rooms structure,
electricity, ..etc.

Enterprise Challenges
The Need of 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.
● Organizations Grew Organically, some Enterprises had a well
defined Architecture, some just emerged/just happened!
Some
are
Designed
Some
just
happened

The Enterprise Architecture (EA)
Making Sense Of Organization Messes
● EA is a way of understanding and managing complex behaviors
of different Enterprise Systems Interactions.
● EA Connects Strategy and Goals to Execution
● EA provides a common basis for understanding and
communicating how systems are structured to meet strategic
objectives
● EA enables flexibility and adaptability, so that business
capabilities can keep pace with changes in strategy.

The Open Group Architectural Framework
TOGAF s View Of Enterprise Architecture
● TOGAF describes itself as a “Framework”
● The most important part of TOGAF is the Architecture
Development Method (ADM). It is a recipe for creating
architecture. A recipe can be categorized as a “Process”.
● However you want to consider TOGAF: “Framework, Process, or
Methodology”, it enables the movement from generic to specific.

Technology Architecture
Technology Architecture includes the core components and technologies in the infrastructure on which
the other layers of the architecture are built. A collection of Technology Roadmap presentations and
Reference Architecture documents provide guidance and a high level strategy for these core technology
investments.
